Gardening in the UK in July: A Comprehensive Guide
July is one of the UK garden’s most vibrant and productive months. The warmth of summer brings gardens into full bloom, with an array of colours, scents, and activities. However, with the heat and long days come challenges that every gardener must be prepared for. Whether tending to your lawn, pruning roses, or keeping an eye on your vegetables, there’s always something to do. This comprehensive guide will walk you through everything you need to know to keep your garden looking its best in July, from managing the typical UK weather to specific tasks for each part of your garden.
Weather in July
July in the UK often brings warm, sunny days and blooming gardens, making it one of the most enjoyable months for gardeners. As summer peaks, understanding the weather conditions in July can help you make the most of your garden. Here’s what to expect and how it relates to your gardening activities.
Warm Temperatures
July typically sees average temperatures ranging from 14°C to 22°C. These warm days create an ideal environment for many plants to thrive. Annuals and perennials flourish, providing vibrant colour throughout the garden. This is also the time for fruiting plants to produce their bounty, including strawberries, raspberries, and courgettes. Keep an eye on your vegetable patch, as regular watering is essential during these hotter months to prevent any moisture stress on your plants.
Sunshine and Daylight
The UK enjoys extended daylight hours in July, with approximately 15 to 16 hours of sunshine daily. This abundance of light promotes vigorous growth and aids in photosynthesis, allowing plants to produce energy efficiently. Position your garden plants to maximise sunlight exposure; this is crucial for heat-loving varieties, such as tomatoes and peppers, that thrive in full sun.
Rainfall Variability
Although July can bring beautiful sunny days, it’s important to note that rain showers can also occur, sometimes unexpectedly. Average rainfall during this month is around 60-80 mm, often coming in quick bursts. While this may provide much-needed moisture, excessively heavy rainfall can lead to waterlogged soil conditions. Ensure your beds have adequate drainage, and consider using mulch around your plants to retain moisture while preventing weed growth.
Pest Vigilance
Summer weather creates a conducive environment for pests and diseases. High temperatures and lush growth can attract aphids, slugs, snails, and other garden nuisances. Regularly inspect your plants for signs of infestation. Employ organic methods to manage these pests, such as natural repellents or encouraging beneficial insects like ladybirds that feast on aphids.
Planning Future Crops
July is also an excellent time for gardeners to plan for autumn crops. Many vegetables, such as kohl rabi, radicchio, and spring cabbage, can be started from seed for harvesting later in the year. This proactive approach ensures you maximise your garden space and yield throughout the changing seasons.
Stay Hydrated
Lastly, during July’s heat, keep yourself hydrated while working in the garden. Ensure your plants receive enough water, especially those newly planted or potted. Water either early morning or late evening to minimise evaporation and help your plants flourish.
In summary, July presents an excellent opportunity for UK gardeners to enjoy their outdoor spaces while tending to the needs of their plants. By understanding the weather patterns and making informed choices, you can create a thriving, colourful garden that flourishes in the warmth of summer.
General Considerations for Gardening in July
Embrace the Warm Weather
July provides an ideal climate for many plants, with temperatures typically ranging from 14°C to 22°C. However, heat can be stressful for some crops. Keep an eye on new plantings or those that are sensitive to heat. Provide shade with netting or cloches during particularly hot days to protect them from sunburn and moisture loss.
Watering Wisely
Watering becomes crucial in July as the soil can dry out quickly. Early mornings or late evenings are the best times to water, as this reduces evaporation and ensures that plants receive the moisture they need. Consider using drip irrigation or soaker hoses to provide consistent moisture to your plants, especially vegetables like tomatoes and cucumbers that thrive in well-watered conditions. Remember to check containers regularly, as they can dry out more quickly than in-ground plants.
Monitor for Pests and Diseases
As summer temperatures rise, so does the risk of pests and diseases. Regularly inspect your plants for signs of aphids, slugs, and fungal issues. Act quickly by introducing beneficial insects or using organic remedies to manage these problems. Spacing plants appropriately to maintain good air circulation can also help prevent fungal diseases.
Deadheading and Pruning
July is the perfect time for deadheading flowers, as this practice encourages more blooms and keeps your garden looking tidy. Remove spent flowers from plants like roses and geraniums to promote further flowering. Additionally, consider lightly pruning shrubs that have finished their initial bloom to encourage new growth and maintain their shape.
Plan for Autumn
While July is all about enjoying the fruits of your labour, it’s also a great time to plan for the upcoming autumn. Start thinking about sowing seeds for winter crops; this proactive approach ensures a continuous harvest throughout the year and makes the most of your gardening space.
Enjoy Your Garden
Finally, don’t forget to take time to enjoy your garden! July’s lively atmosphere makes it perfect for relaxation and outdoor activities. Create seating areas where you can unwind and appreciate the beauty of your hard work. Share your bounty with friends and family, celebrating the fruits of your labour.
In summary, July presents many opportunities and responsibilities for UK gardeners. By embracing the warm weather, watering wisely, monitoring for pests, deadheading regularly, planning for autumn, and enjoying your outdoor space, you can ensure a flourishing and colourful garden throughout the summer.
Lawns
Caring for your lawn in July requires special attention, as the hot, dry weather can stress the grass. One of the most critical tasks is watering. Water deeply and frequently, ideally in the early morning or late evening, to reduce evaporation. Aim for around 2.5 cm (1 inch) of water weekly, ensuring it soaks into the roots for a stronger, healthier lawn.
Mowing
Mow regularly, but keep the mower blades set higher than usual. Taller grass helps shade the soil, retain moisture, and reduce stress on the grass. To prevent lawn weakening, avoid cutting more than one-third of the grass height in a single mow.
Feeding
Apply a summer lawn feed high in potassium to strengthen the grass and improve its drought tolerance. Avoid high-nitrogen fertilisers in the heat, as they encourage rapid, lush growth that can become stressed by dry conditions. If you haven’t already, consider mulching your lawn clippings instead of collecting them. The clippings act as a natural fertiliser, returning nutrients to the soil and helping retain moisture.
Weeds and Pests
Watch for pests and weeds, which can thrive in the summer heat. Remove weeds by hand or use a selective weed killer if necessary. Common weeds like dandelions and clover can compete with your grass for nutrients, so addressing them early will help keep your lawn in top condition.
Stepping Stones
Finally, could you avoid heavy foot traffic on the lawn during dry periods? Compacted soil makes it harder for water and nutrients to reach the roots, weakening the grass. Consider using stepping stones or creating paths to reduce wear and tear on key areas.
Roses
Deadheading & Pruning Roses
Regularly remove spent flowers to encourage more blooms and to prevent the plant from putting energy into seed production. Cut just above the first leaf with five leaflets. While major pruning is done in winter, light pruning can be carried out in July to shape the plants and remove any diseased or damaged growth.
Feeding and Mulching
Roses are heavy feeders; a liquid feed every couple of weeks will help them produce more flowers. Use a fertiliser high in potassium, which is essential for flower development.
Pest and Disease Control
Watch out for common rose pests such as aphids and spider mites. If necessary, use an appropriate pesticide, or try natural methods like introducing beneficial insects. Fungal diseases like black spot and powdery mildew can be controlled with fungicides or by removing affected leaves.
Herbaceous Plants
Watering and Mulching
Herbaceous plants rely on consistent moisture, especially during the hot and dry conditions that July often brings. Water deeply and regularly to keep the soil consistently moist without becoming waterlogged. Early morning or late evening is the best time to water, as this reduces evaporation and allows the plants to absorb the moisture they need to stay healthy.
Consider mulching around your herbaceous plants to help retain moisture and regulate soil temperature. A thick layer of organic mulch, such as compost, straw, or wood chips, can prevent the soil from drying out too quickly and suppresses weed growth. Mulching also improves soil structure as it breaks down, adding valuable organic matter.
Deadheading and Pruning
July is the time to deadhead spent flowers on your herbaceous plants. Removing faded blooms encourages the plant to produce more flowers, extending the blooming period. Regular deadheading also keeps the garden tidy and prevents the plants from wasting energy on seed production.
Pruning is another important task in July. If herbaceous plants have become leggy or overgrown, cut them back to promote fresh, bushy growth. This keeps the plants in shape and improves air circulation, reducing the risk of fungal diseases. Some herbaceous perennials, like geraniums and nepeta, benefit from a mid-season prune to encourage a second flush of flowers later in the summer.
Feeding
July is a good time to feed your herbaceous plants, giving them the necessary nutrients to continue blooming and growing vigorously. Use a balanced liquid fertiliser or a slow-release granular feed, applying it according to the manufacturer’s instructions. Feeding in July helps replenish the nutrients that may have been depleted earlier in the season, especially if your plants are heavy feeders.
Please be aware of overfeeding, as too much fertiliser can lead to excessive foliage growth at the expense of flowers. A balanced approach ensures your plants stay healthy and produce abundant blooms without becoming too leafy.
Pest and Disease Management
July’s warm weather can increase pests and diseases, so keep a close eye on your herbaceous plants. Common pests like aphids, slugs, and snails can cause significant damage if left unchecked. Inspect your plants regularly and take action at the first sign of trouble. Organic pest control methods, such as introducing natural predators like ladybirds or using neem oil, can effectively manage pest populations without harming beneficial insects.
Fungal diseases, such as powdery mildew, can also become a problem in the summer heat, especially in crowded or poorly ventilated areas. Ensure good air circulation by spacing plants appropriately and avoiding overhead watering. If you notice signs of disease, remove and destroy the affected leaves and consider applying a fungicide to prevent the spread.
Supporting and Staking
Many herbaceous plants grow tall and heavy in July and may need extra support to prevent them from flopping over. Stake tall plants early in the month, using garden twine or soft ties to secure them to stakes or supports. This keeps them upright and looking tidy, preventing damage to stems and flowers during windy or rainy weather.
Dahlias and Bulbs
Watering and Feeding
July’s warm weather can dry out the soil quickly, so keeping your dahlias and other bulbs well-watered is essential. Water deeply and consistently to soak the soil down to the roots. Early morning or late evening is the best time to water, reducing evaporation and ensuring the plants can absorb moisture effectively. Avoid watering the foliage directly, as this can promote fungal diseases—focus on the base of the plants instead.
Dahlias and summer-flowering bulbs are hungry plants, especially in full bloom. Feed them every two weeks with a high-potassium fertiliser, such as tomato feed, to encourage healthy flower production. Potassium promotes strong, vibrant blooms, ensuring your plants dazzle throughout the summer. Avoid high-nitrogen fertilisers during this time, as they encourage leafy growth at the expense of flowers.
Deadheading and Pruning
Regular deadheading is crucial in July to keep dahlias and other bulbs flowering. Remove spent blooms as soon as they start to fade. This keeps the plants looking neat and tidy and encourages the production of more flowers. Cut the stem down to a leaf pair for dahlias rather than just removing the flower head—this will promote stronger growth and more blooms.
Pruning isn’t usually necessary for most summer bulbs, but dahlias may benefit from some light pruning if they become leggy or overgrown. Pinch out the tips of the plants early in the month to encourage bushier growth and more flower buds. This technique benefits tall dahlia varieties, helping them maintain a more compact, attractive shape.
Supporting and Staking
Dahlias, especially the taller varieties, often need support to prevent them from flopping over as they grow and bloom. In July, check that all your plants are securely staked. Use sturdy stakes and soft ties to support the stems without damaging them. Insert the stakes early in the growing season to avoid disturbing the roots later on. As the plants grow, tie the stems loosely to the stakes, allowing them some movement while keeping them upright.
For other summer bulbs, like gladioli, staking may also be necessary if they grow tall and top-heavy with flowers. Please ensure that any supports are in place before the stems start bending under the weight of their blooms.
Pest and Disease Management
July’s warm, humid conditions can lead to an increase in pests and diseases. Dahlias are particularly susceptible to aphids, slugs, and snails, which can cause significant damage if left unchecked. Inspect your plants regularly, and remove pests by hand or with an organic pesticide. For slugs and snails, consider using barriers like copper tape or organic slug pellets to protect your plants.
Fungal diseases like powdery mildew can also become a problem in July. Space your plants properly and avoid overhead watering to ensure good air circulation around them. If you notice signs of disease, such as white powdery spots on the leaves, treat them promptly with an appropriate fungicide.
Lifting and Dividing
While lifting and dividing are tasks usually reserved for later in the season, July is a good time to start planning. Suppose you have overcrowded bulbs or have stopped flowering as well as they used to. Consider marking them now to remember which ones need attention in autumn.
Flowers from Seed
Watering
July’s warm temperatures can dry out the soil quickly, making regular watering essential for flowers grown from seed. Water deeply and consistently to keep the soil moist but not waterlogged. Early morning or late evening watering helps reduce evaporation and ensures that your plants absorb the moisture they need. Focus on watering at the base of the plants to avoid wetting the foliage, which can encourage fungal diseases.
Feeding
In July, flowers grown from seed require regular feeding to support their rapid growth and blooming. Apply a balanced liquid fertiliser every two weeks to provide essential nutrients that encourage strong, healthy plants. Choose a fertiliser high in potassium to promote flowering and help your plants produce vibrant, long-lasting blooms.
Deadheading and Pruning
Deadheading is a crucial task in July to keep your flowers blooming continuously. Regularly remove spent flowers by pinching them off just above a set of leaves or buds. This prevents the plant from directing energy into seed production and encourages it to produce more flowers.
Pest and Disease Management
The warm weather in July can increase pests and diseases, quickly damaging flowers grown from seed. Common pests include aphids, slugs, and snails, which can chew through tender young plants. Inspect your flowers regularly, and take action at the first sign of trouble. Remove pests by hand, use organic insecticidal soap, or introduce natural predators like ladybirds to keep pest populations under control.
Fungal diseases such as powdery mildew and botrytis can also affect your plants, especially in humid conditions. To ensure good air circulation, space plants appropriately and avoid overhead watering to keep foliage dry. If you notice signs of disease, remove affected leaves and consider applying a suitable fungicide to prevent further spread.
Supporting and Staking
As your flowers grow in July, they may need extra support to stay upright. Tall plants, such as cosmos or sunflowers, can benefit from staking to prevent them from flopping over in strong winds or heavy rain. Use stakes or bamboo canes to support the plants, tying the stems loosely with garden twine or soft ties to avoid damage.

Vegetable Garden
As July unfolds in the UK, your vegetable garden should be full swing, bursting with colour and life. This vibrant month offers plenty of opportunities to nurture your crops while reaping some of the rewards of your hard work. With the long, warm days ahead, here’s how to make the most of your garden in July.
Harvesting Your Crops
July is a fantastic time to start harvesting a variety of vegetables. Depending on what you’ve planted, you might enjoy the delightful taste of lettuce, radishes, runner beans, and courgettes. Regular harvesting encourages more growth; for instance, the more you pick your courgettes, the better your yield will be. Ensure you harvest in the morning when temperatures are cooler, as this helps maintain the freshness of the vegetables.
Sowing Successive Crops
This month also marks an excellent time for succession sowing to extend your harvest. Directly plant quick-growing crops such as salad leaves, radishes, and spring onions. Sowing these varieties now allows you to enjoy fresh produce all summer long. Space sowings every few weeks to ensure a continuous supply of veggies.
Watering Essentials
With July often bringing warmer weather, consistent watering becomes crucial for your garden’s health. Aim to water your plants early in the morning or late in the afternoon to prevent evaporation. Focus on soaking the soil deeply, especially for thirsty crops like tomatoes and sweetcorn. If you have a rainwater collection system, now’s the perfect time to use it.
Pest Control
As your garden flourishes, so do the pests. Watch out for common villains like aphids, caterpillars, and slugs. Please regularly look over your plants and remove any pests by hand. Consider using organic solutions, such as insecticidal soap or natural predators like ladybirds, to manage infestations without harming beneficial insects.
Supporting Growth
This month, you may need to support some of your taller crops, such as tomatoes and runner beans. Secure them with stakes or bamboo canes, promoting good airflow and reducing the risk of disease. Ensure sufficient space between plants to allow sunlight to penetrate and air to circulate, fostering healthy growth.
Preparing for Autumn Crops
Finally, as you enjoy the bounty of your summer garden, consider preparing for autumn. Later in the month, start sowing winter brassicas, such as cabbages and kales. They will thrive when planted now, ensuring a productive harvest as the season transitions.
Check out the vegetable seeds that can be sown in July here.
Alpines
Watering and Mulching
Alpines typically prefer well-drained soil and can be quite drought-tolerant, but they may require some extra watering in July’s hot weather. Water your alpines early or late in the evening to minimise evaporation. Focus on watering the soil around the plants rather than the foliage, as wet leaves can lead to fungal issues. Ensure the water reaches the roots but avoid waterlogging, as alpines dislike sitting in damp soil.
Mulching around your alpines can help retain moisture and cool the soil, particularly during July’s hot days. Use a light, free-draining mulch like gravel or grit, which complements the natural look of an alpine garden while helping to prevent the soil from drying out too quickly. Avoid using organic mulches like bark, which can hold too much moisture and encourage rot.
Feeding
Your alpines might benefit from light feeding in July to support their growth and flowering. Use a balanced, low-nitrogen fertiliser, as alpines typically don’t need much feeding. A slow-release fertiliser is ideal, providing nutrients gradually over time without overwhelming the plants. If you prefer, you can use a liquid feed diluted to half strength and apply it every few weeks. Be cautious not to overfeed, as too much fertiliser can lead to lush, leggy growth that’s not typical of alpines.
Pruning and Deadheading
July is the perfect time to deadhead your alpines. By removing spent flowers, you encourage more blooms and prevent the plants from putting energy into seed production. Regular deadheading keeps your alpine plants tidy and promotes a longer flowering period.
Some alpines, especially those that spread or grow vigorously, may benefit from a light prune in July. Trim back any excessive growth to maintain the plant’s compact shape and prevent overcrowding. Pruning also improves air circulation, which reduces the risk of fungal diseases, particularly in humid conditions.
Pest and Disease Management
Although alpines are generally resilient, July’s warm weather can bring about some common pests and diseases. Look for aphids, slugs, and snails, which can damage tender new growth. Regularly inspect your alpines and remove pests by hand or use organic treatments like neem oil or insecticidal soap to control infestations.
Fungal diseases such as powdery mildew can also affect alpines in July, especially in areas with poor air circulation. To prevent this, ensure your plants have plenty of space to breathe, and avoid overhead watering. If you notice any signs of disease, please remove the affected parts as soon as possible and dispose of them to prevent the spread of infection.
Weeding and General Maintenance
Weeds can compete with alpines for nutrients and water, so keep your alpine garden weed-free. Hand-pull weeds regularly, being careful not to disturb the shallow roots of your alpine plants. Maintaining a clean, weed-free area around your alpines ensures they have the best conditions to thrive.
Finally, check your rockeries, troughs, or containers to ensure they remain well-drained and in good condition. Remove any debris and reposition any rocks or gravel that may have shifted.
Greenhouses
July is peak growing season in the UK, and your greenhouse is likely buzzing with life. With abundant warmth and extended daylight, it’s the ideal time to keep everything thriving. Whether you’re nurturing tomatoes, propagating new plants, or simply enjoying the shelter of your greenhouse, a few key tasks can make a big difference this month.
Keep It Cool and Well-Ventilated
The July sun can turn your greenhouse into an oven. Open vents and doors early each morning to let hot air escape. Use shade netting or whitewash on the glass to filter intense sunlight. Good airflow reduces humidity and helps prevent fungal diseases. If you can, install an automatic vent opener — it saves time and protects your plants on hot days.
Water Smartly and Regularly
Watering becomes a daily job in July. Aim to water early in the morning or late afternoon to reduce evaporation. Focus on the base of each plant rather than soaking foliage. Tomatoes, cucumbers, and peppers thrive with consistent watering. Group thirsty plants together and consider adding capillary matting or self-watering trays to make your routine easier.
Feed for Growth and Harvest
Fruit-bearing crops need regular feeding now. Use a high-potassium liquid fertiliser, like tomato feed, once or twice weekly. This encourages flowering and better yields. Remove any yellowing leaves and side shoots from tomatoes to direct energy into fruiting. You’ll notice the rewards in both taste and appearance.
Watch for Pests and Disease
Pests love greenhouses in July. Check under leaves and around stems for whiteflies, aphids, and red spider mites. Use sticky traps or introduce natural predators like ladybirds. Keep plants spaced out to avoid overcrowding—good air circulation helps reduce the risk of mould and mildew.
Sow for Late Summer and Autumn
Use the warmth of the greenhouse to start crops for later in the year. Sow winter lettuce, pak choi, and spring cabbage in trays or modules. They’ll establish quickly and be ready to plant out when space becomes available.
Shrubs
July brings warmth, long days, and a garden full of colour and life. While much attention often goes to flowers and veg, your shrubs deserve a little TLC this month. With the proper care, shrubs can stay healthy, vibrant, and beautifully shaped into autumn and beyond.
Prune Early-Flowering Shrubs
Now is the perfect time to prune spring and early summer-flowering shrubs. Plants like philadelphus, deutzia, and weigela benefit from a light prune once their blooms fade. Trim back old flowering stems to encourage fresh growth and a better shape. Use clean, sharp secateurs and cut just above a healthy bud.
Avoid pruning later-flowering shrubs like buddleia or hydrangea, as they’re still gearing up for their big summer show.
Water and Mulch for Summer Health
July can bring hot, dry spells, especially in the southern parts of the UK. Keep your shrubs well watered, particularly those planted last year—water deeply at the base of the plant rather than with a light sprinkle.
After watering, apply a mulch of bark, compost, or well-rotted manure around the base. Mulch helps retain moisture, suppress weeds, and enrich the soil — all great for long-term shrub health.
Feed for Foliage and Flowers
Shrubs growing in containers need regular feeding now. Use a balanced liquid fertiliser every couple of weeks. In borders, a slow-release fertiliser applied earlier in the season should still be doing the job, but if growth looks sluggish, give them a mid-summer boost.
Rhododendrons, camellias, and azaleas will thank you for an acid-loving plant feed as they form next year’s flower buds.
Keep an Eye on Pests and Problems
Shrubs can be prey to pests like aphids or fungal issues like powdery mildew. Check leaves regularly for signs of damage or discolouration. Remove any diseased growth and dispose of it—don’t compost it. Use organic or biological controls where possible to protect pollinators.
Trees
July brings sunshine, warmth, and plenty of growth in the garden. While your trees might look settled and healthy, this month is the perfect time to give them extra care. Trees can thrive with longer days and warmer nights — but only with attention. Here’s how to keep them strong and vibrant through midsummer.
Prune Lightly and Mindfully
July isn’t the time for heavy pruning, but light shaping and removing dead or diseased wood help keep trees healthy. Focus on fruit trees like cherries and plums, as they prefer summer pruning to reduce the risk of silver leaf disease. Use sharp tools and cut above a healthy bud or branch.
Watch for Pests and Disease
Warm weather brings out more than just butterflies. Watch for aphids, scale insects, and caterpillars. Check leaves for curling, discolouration, or sticky residue. Remove pests by hand or use a gentle insecticidal soap if needed. Spotting issues early makes all the difference.
Water Deeply and Mulch Well
If July turns dry, newly planted trees need a weekly soak. Mature trees may cope better, but a long spell without rain can stress even the hardiest. Water slowly close to the base to reach the roots. A generous layer of mulch (such as composted bark or straw) around the base will help retain moisture, suppress weeds, and feed the soil.
Feed for Strength
Apply a slow-release, balanced fertiliser if your trees look tired or show signs of nutrient deficiency. Yellowing leaves or poor growth may suggest they need a boost. Avoid high-nitrogen feeds unless you’re after more leafy growth—a balanced feed is better for fruiting and flowering trees.
Support Young Trees
Stakes and ties can shift as trees grow. Check them now to avoid damage. Ensure the ties aren’t rubbing against the bark, and adjust or loosen as necessary. Strong summer winds can shake younger trees, so ensure they’re well anchored but not constricted.
Climbers
Climbing plants add vertical interest, colour, and a sense of movement to any garden. Whether they’re softening fences or framing doorways, July is the perfect time to give climbers some attention. With the proper care this month, they’ll continue to thrive and bring beauty to your garden throughout the summer.
Tie in and Train New Growth
Climbers grow fast in July; if left unchecked, they can become a tangled mess. Gently tie in new shoots using soft twine or plant ties. Guide them along trellises, wires, or pergolas to keep things neat and encourage a balanced shape. Try to spread growth evenly — this helps light and air reach all parts of the plant.
Secure shoots regularly to stop wind damage and avoid stems flopping or breaking.
Prune After Flowering
Once summer-flowering climbers like clematis montana and climbing roses fade, now’s the time to prune them. Remove spent flowers and cut back long, unruly shoots to encourage fresh growth. This keeps your plants under control and looking their best.
For repeat-flowering roses, deadhead regularly and feed with a high-potash fertiliser to support the next flush of blooms.
Feed and Water Consistently
July climbing plants need consistent moisture, especially those growing in containers or against walls. Water deeply a few times a week rather than little and often. Early morning or evening watering works best.
Apply a balanced liquid feed every fortnight to support flowering and leafy growth. Use mulch around the base to help lock in moisture and suppress weeds.
Check for Pests and Disease
Watch out for aphids, blackspot on roses, and mildew, especially during warm, dry spells. Inspect leaves and stems every few days. Remove any affected parts and use organic controls to protect beneficial insects.
Encourage garden wildlife like ladybirds and birds — they’re natural allies in pest control.
Rhododendrons and Azaleas
Rhododendrons and azaleas are among the most rewarding shrubs, offering a stunning display of colour in spring and early summer. By July, their flowering has usually finished — but this is when your care makes a real difference. With some attention now, you’ll encourage vigorous growth, prepare for next year’s blooms, and keep your plants lush.
Deadhead Spent Blooms
Once flowers fade, gently twist off the dead heads to stop seed production and redirect energy into next season’s buds. Take care not to damage the new shoots forming just below the flower trusses — they’ll carry next year’s display.
Deadheading also keeps plants tidy and prevents mould from building around spent flowers.
Feed and Water Well
Rhododendrons and azaleas need consistent moisture, especially during dry spells in July. Water deeply two to three times a week, ideally with rainwater, as they prefer slightly acidic conditions.
After watering, apply an ericaceous (acid-loving) liquid feed to support strong leaf and bud development. Feeding now helps your shrubs build reserves for next year’s flowering.
Mulch to Conserve Moisture
Using leaf mould, bark chippings, or pine needles, top up the mulch around your plants. This helps conserve moisture, suppress weeds, and maintain soil acidity. Keep the mulch a few centimetres away from the main stem to prevent rot.
Prune Lightly, If Needed
While heavy pruning isn’t ideal in July, you can lightly shape the plant if needed. Trim away leggy or crossing branches and remove any dead or damaged wood. This keeps the plant compact and encourages airflow through the centre.
Check for Pests and Leaf Problems
Keep an eye out for vine weevils, lace bugs, or yellowing leaves — signs of poor drainage or nutrient deficiency. Use organic pest controls and check the soil pH to see if your plant looks unwell or has signs of poor drainage or nutrient deficiency.
Healthy leaves should stay deep green — if they’re pale or curling, your plant may need a bit more care.
Hedges
July brings lush growth to UK gardens; your hedges are no exception. Whether formal or informal, evergreen or deciduous, hedges shape your garden’s structure and privacy. This month is ideal for trimming, feeding, and checking the health of your hedge so it stays neat, thick, and thriving.
Time to Trim and Shape
July is perfect for giving your hedge its summer haircut. Most hedges, including box, privet, beech, hornbeam, and yew, will have completed their main flush of growth by now. Use clean, sharp shears or a hedge trimmer to shape and tidy up the sides and top. Keep the base slightly wider than the top to allow even light distribution.
For formal hedges, aim for a crisp line. Step back regularly to check your symmetry. Informal hedges need less precision but still benefit from a tidy-up to encourage bushiness and remove straggly growth.
Look Out for Birds Before Cutting
Before you begin trimming, always check for nesting birds. The nesting season can extend into July. If you see active nests, delay cutting until later in the month or once fledglings have left.
Feed for Strength and Colour
After trimming, boost your hedge with a slow-release fertiliser or a general-purpose feed. Feeding now supports recovery after cutting and encourages healthy new growth. If your hedge looks pale, liquid seaweed or high-nitrogen feed will help green it up.
Watering During Dry Spells
If July brings long dry periods, water your hedges thoroughly once or twice a week. This is especially important for newly planted or shallow-rooted hedges like laurel or privet. You can use mulch around the base to keep moisture and suppress weeds.
Watch for Pests and Problems
Look for pests like aphids or signs of leaf spot, especially in dense hedges. Trim out infected sections and use organic sprays where needed.
Fruit
July is a rewarding month for fruit growers in the UK. Berries ripen, apples swell, and stone fruits blush with colour. Now’s the time to enjoy the fruits of your labour while giving your plants a little mid-season attention to keep them healthy and productive.
Pick Ripe Fruit Regularly
Harvest soft fruits like raspberries, gooseberries, blackcurrants, and strawberries every few days. Regular picking encourages more fruiting and helps prevent waste. Pick in the cool morning for the best flavour and eat or freeze soon after.
Blueberries and cherries also reach their peak this month. Protect ripening fruit from birds using netting, but check it daily to ensure no wildlife gets tangled.
Water Deeply and Mulch Well
Fruit trees and plants need consistent moisture through July, especially during hot, dry spells. Deep watering twice a week is better than a light daily sprinkle. To retain moisture and suppress weeds, Mulch around the base with compost or well-rotted manure.
Pay close attention to container-grown fruits, which dry out faster. Keep them well-watered and feed them with a high-potash liquid fertiliser every fortnight.
Prune and Train Where Needed
Now is a great time to summer prune espalier, cordon, or fan-trained apple and pear trees. Trim back side shoots to encourage fruiting spurs and keep the framework tidy. Remove crossing branches and those growing inwards.
Tie in new growth on grapevines, blackberries, and trained trees to help shape their structure and improve airflow.
Support Heavily Laden Branches
Some branches will sag under the weight of growing fruit. Use soft ties and canes to support apples, pears, and plums. Thinning fruit on trees helps improve quality and reduces the risk of branches snapping.
Feed for Continued Growth
If established fruit trees and bushes’ growth appears pale or slow, feed them with a balanced fertiliser. This helps maintain energy levels through fruiting and strengthens plants ahead of autumn.
Houseplants
July brings sunshine and warmth, and your houseplants love it, in moderation. Houseplants enter their peak growing season with longer daylight hours and higher temperatures. This is the perfect time to give them some extra care, keep them thriving, and even encourage new growthextra care, keep them thriving, and.
Watch Out for Heat and Light Stress
Sunlight streams through windows for more extended periods in July. While most houseplants enjoy extra light, direct sunlight can scorch leaves. Move sensitive plants like ferns, calatheas, and peace lilies away from south-facing windows. Use sheer curtains to soften strong sunlight if needed.
Rotate your pots every few days to promote even growth and prevent plants from leaning towards the light. Look for dry, crispy leaf edges—a sign that they’re getting too much heat.
Watering Needs Change with the Weather
Most houseplants need more water during summer. Check the soil frequently and water when the top couple of centimetres feel dry. Avoid overwatering—soggy soil can lead to root rot. Always empty saucers to prevent roots from sitting in water.
Plants in terracotta pots dry out faster and may need watering more often. Grouping plants can help increase humidity, which many tropical species appreciate.
Feed for Healthier Growth
July is the perfect time to feed your houseplants. Use a general liquid houseplant fertiliser every two to four weeks. For flowering types like orchids or African violets, switch to a bloom-boosting feed high in potassium.
Fertilise after watering, not when the soil is dry, to prevent root burn. Stop feeding if a plant looks unwell—check for pests or root problems first.
Time to Repot or Propagate
If your houseplants have outgrown their pots, now is a great time to repot. Choose a pot just a little larger and use fresh compost. Trim back long roots and remove old soil where possible.
Many houseplants, like pothos, spider plants, and succulents, can be propagated from cuttings in summer. It’s a fun and easy way to grow your collection or share with friends.
Patios
July is the height of summer in the UK, and there’s no better time to make the most of your patio. Whether hosting family barbecues, enjoying a peaceful morning coffee, or just soaking up the sun, your patio becomes an outdoor hub this month. With a few easy updates, you can turn it into a vibrant and inviting space that works beautifully through the rest of summer.
Give Your Patio a Good Clean
Start by clearing any debris or fallen petals. Use a broom or leaf blower to sweep off dirt and dust. A pressure washer quickly refreshes paving stones, removing algae and stains built up over spring. Keep on top of regular cleaning to stop weeds from growing between cracks. For stubborn weeds, use a patio knife or natural weed killer.
Add Colour with Pots and Containers
Now is the perfect time to bring your patio to life with bold, colourful containers. Choose a mix of bedding plants, trailing varieties, and scented herbs to create an inviting atmosphere. Geraniums, petunias, and lavender thrive in sunny spots. Water daily during hot spells and feed weekly to keep displays at their best.
Rearrange pots to change the layout and experiment with height using plant stands, crates, or even steps.
Check Your Furniture and Accessories
Inspect your patio furniture for wear. Wipe everything down, tighten screws, and touch up paint if needed. Add cushions and throws for comfort and a pop of colour. Solar lights, lanterns, and string lights help extend patio enjoyment well into the evening.
If you don’t have shade, consider adding a parasol, awning, or pergola with climbing plants for natural cover.
Create a Relaxing Green Space
Introduce structure with small trees in pots like bay, olive, or dwarf Acer. Place them at the corners to frame your seating area. Add interest with ornamental grasses and evergreen shrubs in containers. A water feature, bird bath, or garden sculpture can create a peaceful focal point.
From Darren’s Patch
July is when the garden truly hits its stride — full, fragrant, and buzzing with life. I love this time of year. There’s something deeply satisfying about picking fresh courgettes or plump raspberries straight from the plant, still warm from the sun. One habit I swear by is checking the garden each evening, with secateurs in one hand and a watering can in the other — a quick deadhead here, a slug picked off there. It keeps me connected and on top of things without ever feeling like a chore. I also like to sneak in a bit of sowing for autumn — kohl rabi and spring cabbage go in now, filling the gaps where early crops have finished. And when the sun starts to dip, there’s nothing better than sitting out with a cup of coffee, surrounded by all that colour and life. July in the garden is pure joy — don’t miss a moment.
Conclusion
July in the UK garden is about energy, colour, and growth. With longer days and warmer temperatures, this is the time to enjoy your outdoor space truly. Whether nurturing vegetables, pruning shrubs, or relaxing on the patio, your garden offers endless ways to stay connected with nature.
Keep the Momentum Going
By now, many plants are in full bloom, and fruits are ripening. It’s rewarding to see your hard work paying off. Keep feeding and watering regularly, especially during hot, dry spells. Check for pests and diseases often to act quickly if anything looks out of place. Deadhead flowering plants and harvest crops like courgettes, beans, and tomatoes to keep production going.
This is also the ideal month to take notes and photos. Document what’s thriving and where improvements could be made. These will help when planning next season’s layout or planting schemes.
Take Time to Enjoy It
Gardening isn’t just about the jobs—it’s about relaxing and appreciating your creation. Sit back in your favourite spot with a cuppa or enjoy the scent of blooming flowers. Invite friends or family to share a meal outside and show off your garden at its best.
Use this month to observe how the sun moves across your space and think about longer-term changes you might want to make. Maybe it’s time for a new border, raised beds, or a wildlife-friendly corner.
Looking Ahead
Consider late summer and early autumn crops as July draws to a close. You can now sow fast-maturing salads, beetroot, and radishes for harvest in early autumn. It’s also a great time to prepare your garden for planting hardy biennials or perennials in August.
Keep your gardening tools clean and organised, ready for the next wave of activity. Every small task you complete now helps build a better garden for the months to come.
