Gardening in the UK in February: A Comprehensive Guide
February marks the tail end of winter in the UK, a month where the days start to lengthen, and the first signs of spring begin to appear. While the weather remains cold, with frosty mornings and the occasional snowfall, there is a sense of anticipation in the garden as plants prepare to burst into life. For gardeners, February is a month of preparation and planning, with tasks focused on readying the garden for the upcoming growing season.
Weather in February
February bridges winter and spring in UK gardens, with temperatures typically ranging from 1°C to 8°C. Understanding these conditions helps gardeners prepare effectively for the growing season ahead.
Increasing daylight hours mark a significant change from January, stimulating early growth in bulbs and perennials. However, frost remains a risk, particularly early in the month. Protect tender plants with horticultural fleece or cloches when needed.
Rainfall often leads to waterlogged soil, making garden access challenging. Assess ground conditions before working to avoid soil compaction. If weather permits, focus on improving drainage systems or creating raised beds for better resilience.
February presents excellent opportunities for indoor seed sowing, especially for chillies, peppers, and early tomatoes. Use greenhouses or sunny windowsills to give seedlings a strong start before outdoor transplanting after the last frost.
This month also suits pruning deciduous shrubs and trees, encouraging healthy spring growth. Choose dry days for these tasks to ensure optimal results.
By understanding and working with February’s weather patterns, gardeners can maximise this crucial preparation time, setting their gardens up for success in the coming growing season.
General Considerations for Gardening in February
February is a crucial month for gardeners in the UK, marking the transition from the depths of winter to the beginnings of spring. Understanding the general considerations for gardening during this time can set the stage for a thriving garden in the warmer months ahead.
Weather Awareness
February often brings unpredictable weather patterns. Gardeners must stay alert to fluctuations in temperature and rainfall. While daytime temperatures can range from 1°C to 8°C, unexpected cold spells can still occur, leading to frost. It’s essential to monitor weather forecasts and be prepared to cover tender plants with horticultural fleece or cloches to protect them from potential frostbite.
Soil Management
The winter months often leave soil in a wetter state, and February can be no exception. Waterlogged soil can hinder growth and lead to compaction problems. Before working the soil, ensure it’s not too wet. A simple test involves squeezing a handful of soil; if it crumbles, it’s ready to be worked, but if it forms a ball, wait until it dries out a bit. Consider adding organic matter, such as compost, to improve soil structure and drainage.
Sowing and Planting
February serves as a fantastic time for planning your planting strategies. For vegetable gardeners, now is the moment to start sowing seeds indoors. Consider varieties like chillies, peppers, and early tomatoes. A greenhouse or a sunny windowsill provides the perfect environment for these young plants. Mark your calendars for when to transplant them outdoors, taking care to avoid late frosts.
Pruning Duties
Many deciduous shrubs and trees benefit from pruning during February. Focus on removing dead or damaged wood, which helps encourage fresh growth in spring. This practice not only maintains the shape of the plants but also improves airflow, significantly reducing the chances of disease. Always use clean, sharp tools for the best results.
Lawn Care
If your garden includes a lawn, February is an ideal time for maintenance. As temperatures warm slightly, you may find the grass begins to awaken from winter dormancy. Raking up any debris like leaves or twigs allows sunlight to reach the grass and encourages healthy growth. You can also use this time to aerate your lawn, promoting better drainage.
Planning for Colour
Finally, February serves as an excellent month for planning your ornamental garden. Consider adding spring-flowering bulbs like daffodils and tulips, which can provide beautiful bursts of colour. Preparing your flowerbeds now will ensure a vibrant display as winter fades away.
In conclusion, February is a vital month for UK gardeners. By staying aware of weather conditions, managing your soil, planning planting schedules, completing necessary pruning, caring for your lawn, and thinking about colour, you can set the groundwork for a flourishing garden once the warmer months arrive. Embrace February as a time for preparation, and watch your garden thrive!
Lawns
Lawn care in February is focused on protecting the grass from the lingering winter conditions and preparing it for the growing season ahead. By taking the right steps now, you can ensure your lawn remains healthy and ready to thrive when the warmer weather returns.
Avoiding Lawn Damage
Avoiding lawn damage from frost and snow is crucial in February. The grass may still be dormant or just beginning to wake up, so it’s important to minimise foot traffic on the lawn, especially when it’s frosty or wet. Walking on frozen grass can cause compaction and damage the grass blades, leading to bare patches and poor growth in the spring. If you need to access certain areas of the garden, try to use stepping stones or temporary paths to minimise damage.
Managing Moss
Clearing debris and managing moss are important tasks in February. Fallen leaves, twigs, and other debris can smother the grass, blocking out light and air, which can lead to the development of moss and other problems. Regularly rake up leaves and either compost them or use them as mulch in other areas of the garden. If moss has taken hold over the winter, consider applying a moss killer towards the end of the month. Once the moss has turned black, rake it out to allow the grass to breathe and prepare for the first mow.
Aeration
Aerating and preparing for spring growth are essential for lawns in February, particularly in areas prone to water-logging. Aerating the lawn by spiking it with a garden fork or using a mechanical aerator can help improve drainage and reduce compaction. This allows air, water, and nutrients to penetrate the soil, promoting healthier grass growth. If the soil is compacted, consider applying a top dressing of sand and loam to improve soil structure and drainage.
The First Mow of the Season
The first mow of the season can be done in late February if the weather conditions allow. Choose a dry day when the grass is not too wet or frosty, and set the mower blades higher than usual to avoid scalping the lawn. Mowing the lawn helps to remove dead grass and encourages new growth. However, if the weather remains cold and wet, it’s better to wait until March for the first mow.
Roses
Roses require special attention in February as they begin to wake up from their winter dormancy. Proper care now will help protect them from late winter frosts and prepare them for a strong start to the growing season.
Winter Protection
Winter protection and mulching are still important for roses in February, especially in colder regions. If you haven’t already done so, ensure that the roots are well insulated by applying a thick layer of mulch, such as compost or well-rotted manure, around the base of the plants. This mulch helps retain moisture, suppress weeds, and provide insulation against temperature fluctuations. In areas prone to late frosts, consider providing additional protection, such as wrapping the stems with horticultural fleece or burlap.
Pruning Roses
Pruning roses in late February is one of the key tasks for this month. Pruning encourages healthy growth and improves the structure of the plant. Start by removing any dead, diseased, or damaged wood. Then, cut back the remaining healthy stems to just above an outward-facing bud, which encourages the plant to grow outward and improves air circulation. For hybrid tea and floribunda roses, prune back to about 15-30 cm (6-12 inches) above ground level. Climbing roses can also be pruned, focusing on removing any weak or crossing stems and tying in new growth to the support.
Preparing for the Growing Season
Preparing roses for the growing season involves ensuring they have the right nutrients and conditions to thrive. Once you’ve completed pruning, consider applying a balanced fertiliser around the base of the plants to give them a boost of nutrients as they start to grow. Water the roses well after fertilising, and keep an eye on the weather forecast to protect new growth from late frosts.
Herbaceous Plants
Herbaceous plants are the backbone of the garden, providing colour, texture, and variety throughout the growing season. April is the time to give these plants the care they need to thrive.
Tidying Up
Cutting back old growth and tidying borders are key tasks in February. Many herbaceous perennials will have died back completely over the winter, leaving behind dead stems and foliage. Cut back any remaining dead growth to ground level and remove it from the garden. This not only improves the appearance of the garden but also helps to prevent pests and diseases from taking hold in the dead plant material. Tidying up the borders will also make room for new growth as the plants begin to emerge.
Dividing and Replanting
Dividing and replanting perennials can be done in February, particularly for early-blooming plants that benefit from being divided before they start growing vigorously. Dividing helps to rejuvenate the plant, encouraging more vigorous growth and better flowering later in the season. It also provides an opportunity to create new plants for other areas of the garden or to share with friends. When replanting, ensure the plants are well-watered and mulched to help them establish before the growing season kicks in.
Mulching
Mulching and protecting new shoots is crucial in February, especially in regions prone to late frosts. Apply a thick layer of organic mulch, such as compost, leaf mould, or well-rotted manure, around the base of your perennials. This mulch helps to retain moisture, suppress weeds, and provide insulation against temperature fluctuations. As new shoots begin to emerge, consider covering them with horticultural fleece or cloches to protect them from frost damage.
Pest and Disease
Pest and disease management remains important in February, as cool, damp conditions can lead to problems such as slugs, snails, and mildew. Regularly inspect your herbaceous plants for signs of pests or disease, and take action promptly to prevent any issues from becoming severe. Removing any diseased foliage and applying organic pest controls, such as slug pellets or barriers, can help keep your plants healthy as they begin to grow.
Dahlias and Bulbs
February is a time to start preparing dahlias and other summer bulbs for planting, as well as checking on stored bulbs to ensure they are ready to grow when the weather warms up.
Preparing Dahlia Tubers for Planting
Preparing dahlia tubers for planting is an important task in February. If you’ve stored dahlia tubers over the winter, now is the time to check them for any signs of rot or damage. Remove any soft, discoloured, or mouldy tubers to prevent the problem from spreading. In warmer regions, you can start to pot up the tubers indoors to give them a head start before planting them outside in the spring. Plant the tubers in pots filled with fresh compost, water lightly, and place them in a bright, frost-free location. Keep an eye on the weather and only plant them outdoors once the risk of frost has passed.
Early Planting of Summer Bulbs
Checking stored bulbs and early planting can be done in February, especially for bulbs such as lilies and begonias that benefit from an early start. Inspect stored bulbs for any signs of rot or pests, and discard any that are damaged. If the conditions are right, you can start planting these bulbs in pots indoors or in a greenhouse to give them a head start before transferring them to the garden later in the spring. Make sure the pots have good drainage, and water the bulbs sparingly until they start to grow.
Late Planting of Spring Flowering Bulbs
Planting spring-flowering bulbs is still possible in early February, particularly in milder regions where the ground is workable. The flowering time will be later but the bulbs will be established for next year. Bulbs such as tulips, daffodils, and crocuses can still be planted if you haven’t already done so. Plant the bulbs at a depth of about three times their height, with the pointed end facing upwards. Water the bulbs well after planting, and consider applying a layer of mulch to help retain moisture and protect them from frost.
Pest and Disease Control
Preventing bulb rot and pests is crucial for ensuring healthy growth. Slugs, snails, and other pests can be a problem for newly emerging shoots, so use organic pest controls, such as slug pellets or barriers, to protect your bulbs. Make sure to water the bulbs sparingly, as overwatering can lead to rot. If you’re planting bulbs in containers, ensure they are raised off the ground to prevent water-logging and frost damage.
Flowers from Seed
February is an ideal time to start sowing flowers from seed, giving you a head start on the growing season and allowing you to enjoy a wide variety of blooms throughout the year.
Sowing Hardy Annuals and Perennials
Sowing hardy annuals and perennials indoors is a popular task in February. Flowers such as sweet peas, larkspur, and delphiniums can be sown in pots or trays filled with good-quality compost and placed in a cold frame, unheated greenhouse, or a sheltered spot indoors. These plants benefit from being sown early, as they will establish strong roots over the winter, leading to more vigorous growth and earlier blooms in the spring. Once the seedlings have developed a few sets of leaves, pinch out the tips to encourage bushier growth.
Starting sweet peas and other early bloomers indoors is a great way to get a jump on the growing season. Sweet peas, in particular, benefit from being sown in February, as they will establish strong roots and be ready to plant out as soon as the weather warms up. Sow the seeds in deep pots or root trainers to give the roots plenty of room to grow. Keep the pots in a cold frame or unheated greenhouse, and water sparingly until the seedlings are established. Other early bloomers, such as cosmos and marigolds, can also be started indoors in February for an early start to the growing season.
Caring for Seedlings
Once your seeds have germinated and the seedlings have grown large enough to handle, it’s important to thin them out to prevent overcrowding. Thin them to the recommended spacing on the seed packet, usually when the seedlings have two sets of true leaves. Use the thinned-out seedlings to fill gaps in other parts of the garden or give them to friends and neighbours.
Preparing Beds
Preparing beds for outdoor sowing is another important task in February. Clear any remaining plant debris and weeds from the beds, and add a layer of compost or well-rotted manure to improve the soil structure and fertility. If you plan to sow seeds directly into the ground in the spring, consider covering the beds with black plastic or horticultural fleece to keep the soil warm and prevent weeds from taking hold. This will help create the ideal conditions for your seeds to germinate when you’re ready to sow them outdoors.
Vegetable Garden
As February sets in across the UK, gardeners can feel the anticipation of spring. This month serves as a bridge between winter’s chill and the vibrant growing season ahead. While the garden may still appear dormant, there are plenty of tasks to engage in that lay the groundwork for a fruitful vegetable garden. Here’s how you can make the most of your garden in February.
Finish Winter Pruning
February is your last chance to finish winter pruning of fruit trees and bushes. Prune apple and pear trees to encourage healthy growth and maximise fruit yields later in the year. For berry bushes like autumn-fruiting raspberries, now’s the time to keep them in shape and promote strong new growth. Remove any dead or overcrowded branches, ensuring good air circulation.
Sowing Indoor Seeds
If you’re itching to start your gardening journey, get indoors and sow seeds for early crops. This is the ideal time to plant chillies, peppers, tomatoes, and aubergines in seed trays or pots. Place them on a sunny windowsill or under grow lights. Use quality seed compost and keep the soil moist. Soon, you’ll see small sprouts, providing a thrilling start to your gardening season.
Prepare Outdoor Seedbeds
Once the ground is workable—meaning it’s not frozen or waterlogged—you can prepare outdoor seedbeds. Clear away any weeds and debris, then loosen the soil with a fork to improve drainage. You can start sowing hardy varieties directly, such as broad beans and early carrots, particularly if you live in a milder area. For those growing in heavier soils, wait until mid-March for better conditions.
Planting Garlic and Shallots
February is a great month to plant garlic and shallots. If you haven’t already, plant them in well-drained soil where they can receive plenty of sunshine. Space them apart to allow for healthy growth. Garlic loves to thrive in fertile soil, so consider adding compost to enhance nutrient levels.
Protecting Against Frost
As the weather can still be unpredictable, protect your young plants from late frosts. Cover outdoor seeds with horticultural fleece or cloches on particularly cold nights. This simple measure keeps your plants cosy and can make a significant difference in their survival.
Maintenance and Weeding
Use this month to get ahead on weeding and garden maintenance. Clear away any last season’s plant debris to reduce pests and diseases. Also, check stored crops like potatoes and carrots, removing any that show signs of rot.
Alpines
Alpines are resilient plants that can withstand cold temperatures, but they do require some specific care in February to ensure they survive the winter in good health. Proper attention now will help your alpines return strong and healthy in the spring.
Winter Care of Alpines
Protecting alpines from winter wet is crucial in February, particularly in areas with heavy rainfall. Alpines are adapted to thrive in well-drained conditions, and too much moisture can lead to root rot, particularly as the days become shorter and the soil stays damp for longer periods. Ensure that your alpines are planted in well-drained soil, and consider adding grit or sand to improve drainage if necessary. In areas prone to heavy rainfall, you might want to cover the plants with a cloche or an open-ended cold frame to keep the worst of the weather off.
Mulching
Mulching and insulating crowns is another important task for alpines in February. While many alpines are hardy and can tolerate cold temperatures, they can be vulnerable to frost heave, where repeated freezing and thawing of the soil can push the plants out of the ground. Apply a layer of grit, gravel, or sand around the base of the plants to help prevent this. This mulch also helps to protect the crowns of the plants from frost and reduces the risk of rot.
Managing Pests and Diseases
Managing winter pests is generally straightforward with alpines, as their tough nature makes them less susceptible to problems. However, it’s still important to keep an eye out for common issues such as aphids or fungal diseases, particularly during wet weather. Regularly inspect your plants, and remove any affected parts promptly to prevent the spread of disease.
Water Plants and Ponds
February is a critical month for maintaining water plants and ponds as you prepare for the remainder of the winter. Proper care now will ensure that your pond remains healthy and attractive, providing a haven for wildlife throughout the year.
Prevent Freezing
Preventing pond freezing and maintaining water quality are key tasks in February. As temperatures drop, ponds can freeze over, preventing oxygen from entering the water and endangering fish and aquatic plants. If your pond freezes, carefully pour warm (not hot) water onto a small area to create an opening. Avoid smashing the ice with a hammer or heavy object, as this can shock and harm the fish. To prevent the pond from freezing over completely, consider installing a pond heater or floating device to keep a small area ice-free.
Protecting fish and aquatic plants from freezing is crucial during the winter months. Ensure that the pond is deep enough to prevent it from freezing solid. Move tender aquatic plants, such as water lilies, to deeper parts of the pond or bring them indoors to a frost-free location, such as a greenhouse. For more delicate fish, consider adding a pond cover or netting to protect them from predators and falling debris. If the pond is in an exposed area, installing windbreaks can help reduce the wind chill and prevent the water from freezing as quickly.
Prepare for Spring
Planning for spring pond care involves taking steps now to ensure your pond is ready for the warmer months. Regularly check the water clarity and use a pond vacuum or net to remove any debris, such as fallen leaves, that may have accumulated. If necessary, consider adding a barley straw extract or a commercial pond treatment to help control algae and maintain clear water. Reducing the feeding of fish as the water temperature drops is also important, as fish become less active and require less food in colder weather.
Greenhouses
The greenhouse remains a vital part of the garden in February, offering a controlled environment where you can protect tender plants from frost and continue growing throughout the winter. As the weather cools, the focus shifts to ensuring the greenhouse is well-insulated and prepared for the remaining winter months.
Insulation and Temperature Control
Insulating and managing temperature in the greenhouse is one of the main tasks in February. As temperatures drop, it’s important to keep the greenhouse warm enough to protect your plants from frost. Consider adding insulation, such as bubble wrap, to the inside of the greenhouse to help retain heat. If your greenhouse is heated, check the heating system to ensure it’s working correctly before the cold weather sets in. Set the thermostat to maintain a minimum temperature that suits the plants you’re growing, typically around 5-10°C (41-50°F) for most tender plants.
Sowing
Sowing early vegetables and flowers is a great way to make the most of your greenhouse in February. Hardy vegetables, such as winter lettuce, spinach, and radishes, can be sown in pots or directly into the greenhouse borders. These crops will grow slowly through the winter, providing fresh produce when outdoor gardening is limited. Use fresh compost and ensure the pots have good drainage to prevent water-logging. You can also plant flowers, such as sweet peas and early spring bulbs, in pots to force them for an early display.
Light, Humidity and Ventilation
Sowing early vegetables and flowers is a great way to make the most of your greenhouse in February. Hardy vegetables, such as winter lettuce, spinach, and radishes, can be sown in pots or directly into the greenhouse borders. These crops will grow slowly through the winter, providing fresh produce when outdoor gardening is limited. Use fresh compost and ensure the pots have good drainage to prevent water-logging. You can also plant flowers, such as sweet peas and early spring bulbs, in pots to force them for an early display.
Ventilation is important to prevent the buildup of excess humidity, which can lead to fungal diseases. On milder days, open the vents or doors of the greenhouse to allow fresh air to circulate. This helps to reduce humidity and prevent problems such as grey mould (Botrytis) or powdery mildew. If your greenhouse is equipped with an automatic ventilation system, check that it is functioning correctly and adjust the settings as needed.
Pests and Diseases
Pest and disease management remains important in the greenhouse, even as the growing season winds down. Warm, humid conditions can lead to problems such as whitefly, aphids, or spider mites. Regularly inspect your plants for signs of pests or disease, and take action promptly if you notice any issues. Organic treatments, such as insecticidal soap or neem oil, can be effective in controlling pests without harming beneficial insects. Ensure good air circulation in the greenhouse by opening vents on warmer days to reduce humidity and prevent fungal problems.
Shrubs
Shrubs provide structure and form to the garden, offering year-round interest with their foliage, flowers, and berries. April is an important month for pruning, feeding, and planting shrubs.
Pruning Early-Flowering Shrubs
Many shrubs that flower in early spring, such as forsythia and flowering currant, should be pruned immediately after they finish blooming. Pruning at this time encourages strong new growth and ensures a good display of flowers the following year. Cut back any flowering shoots to a healthy pair of buds, and remove any dead or diseased wood. If the shrub has become too large or congested, you can also thin it out by removing some of the older stems at the base.
Feeding and Mulching
April is the time to feed your shrubs to support their growth throughout the growing season. Apply a balanced fertiliser around the base of each shrub, and then mulch with organic material such as compost, leaf mould, or well-rotted manure. Mulching helps retain moisture, suppress weeds, and improve soil structure. Be sure to keep the mulch away from the base of the shrub to prevent rot.
Planting New Shrubs
If you’re adding new shrubs to your garden, April is a great time to plant them. The soil is warming up, and the plants will have plenty of time to establish before the heat of summer. Choose a suitable spot for your shrub, considering its mature size and light requirements. Dig a hole that is twice as wide and the same depth as the root ball, and mix in some compost or organic matter. Place the shrub in the hole, backfill with soil, and water well.
Trees
Trees are a long-term investment in your garden, providing shade, structure, and beauty. April is a crucial month for tree care, from pruning to planting new specimens.
Inspecting for Damage and Disease
As trees come out of dormancy, it’s important to inspect them for any signs of damage or disease that may have occurred over the winter. Look for dead or damaged branches, signs of fungal infections, and any evidence of pests such as aphids or caterpillars. Remove any affected areas and dispose of them carefully. If you notice any serious issues, it may be necessary to consult a professional arboriculturist.
Pruning and Shaping
Most deciduous trees should be pruned while they are still dormant or just as they begin to leaf out in spring. Pruning helps to shape the tree, remove dead or crossing branches, and improve air circulation. Use sharp, clean tools to make clean cuts, and avoid removing more than a third of the tree’s growth in a single year. For trees that bleed sap, such as birch and maple, it’s better to wait until later in the year to prune.
Planting and Staking Young Trees
If you’re planting a new tree in your garden, April is a good time to do it. Choose a suitable spot with enough space for the tree to grow to its full size. Dig a hole that is at least twice the width of the root ball and the same depth. Loosen the soil at the bottom of the hole to help the roots establish. Place the tree in the hole, backfill with soil, and water well. If the tree is tall or in a windy spot, stake it to prevent it from being damaged by strong winds.
Climbers
Climbers add vertical interest to the garden, covering walls, fences, and trellises with lush foliage and beautiful blooms. April is the time to train, prune, and plant climbers.
Supporting and Training Climbers
As climbers begin their vigorous spring growth, it’s important to provide them with the support they need. Check that trellises, wires, and other supports are secure and strong enough to hold the weight of the growing plant. Gently tie in new shoots using soft garden twine, ensuring that the plant is evenly distributed across the support. This will help to create a balanced and attractive display.
Pruning and Feeding
April is the time to prune early-flowering climbers such as Clematis montana and Wisteria. For Clematis, remove any dead or damaged stems, and trim back the flowering shoots to a pair of strong buds. Wisteria should be pruned back to three buds from the base of the flowering shoots. After pruning, apply a balanced fertiliser to encourage healthy growth and abundant flowering.
Planting New Climbers
Apply a balanced fertiliser around the base of your climbers to give them a nutrient boost as they come into active growth. Mulch with organic matter to retain moisture and suppress weeds.
Planting New Climbers
If you’re planting new climbers, April is an excellent time to do so. Choose a suitable spot with good drainage and plenty of sunlight. Dig a hole that is twice the width of the root ball and mix in some compost or organic matter. Plant the climber at the same depth it was in the pot, and angle it slightly towards the support. Water well and mulch around the base to help retain moisture.
Rhododendrons and Azaleas
Rhododendrons and azaleas are a favourite in UK gardens, known for their vibrant blooms and attractive foliage. April is a key month for their care.
Feeding and Mulching
Rhododendrons and Azaleas thrive in acidic soil, so it’s important to feed them with an ericaceous fertiliser in April. This will provide the nutrients they need to produce their stunning flowers. After feeding, apply a layer of mulch around the base of the plants to help retain moisture and suppress weeds. Use organic material such as leaf mould, pine needles, or composted bark, which will also help to maintain the soil’s acidity.
Deadheading Spent Blooms
Once your Rhododendrons and Azaleas have finished flowering, it’s a good idea to deadhead the spent blooms. This prevents the plant from wasting energy on seed production and encourages it to put its energy into producing new growth. Gently snap off the dead flowers just above the first set of leaves, being careful not to damage the new buds that may be forming underneath.
Managing Soil Acidity
Rhododendrons and azaleas require acidic soil to thrive, so it’s important to monitor the pH level of your soil. If your soil is not naturally acidic, you can lower the pH by adding sulphur or using an ericaceous compost. Mulching with acidic materials such as pine needles can also help to maintain the right soil conditions. If you’re planting new Rhododendrons or Azaleas, consider creating a raised bed filled with ericaceous compost to provide the ideal environment for them.

Hedges
Hedges are an essential feature of many gardens, providing privacy, shelter, and a habitat for wildlife. April is the time to give them the care they need to look their best.
Trimming and Shaping
If your hedges have grown untidy over the winter, April is the time to trim and shape them. Use sharp hedge shears or a hedge trimmer to cut back any overgrown sections, creating a neat, even shape. For formal hedges, use a string line or stakes to guide your trimming and ensure a straight edge. If you’re trimming a flowering hedge, such as hawthorn or forsythia, wait until after it has finished flowering to avoid cutting off the blooms.
Feeding and Mulching
After trimming, it’s important to feed your hedge to promote healthy growth. Apply a balanced fertiliser along the base of the hedge, and then mulch with organic material such as compost or well-rotted manure. Mulching helps to retain moisture, suppress weeds, and improve the soil structure. Be sure to keep the mulch away from the stems of the hedge to prevent rot.
Planting New Hedges
If you’re planting a new hedge, April is a great time to do it. Choose a suitable spot with enough space for the hedge to grow to its full size. Dig a trench rather than individual holes, as this will encourage the hedge to grow as a continuous row. Mix in some compost or organic matter, and plant the hedge plants at the same depth they were in the pot. Water well after planting, and mulch around the base to help retain moisture.
Fruit
Growing your own fruit is one of the most rewarding aspects of gardening. April is a busy month for fruit growers, with plenty of tasks to ensure a bountiful harvest later in the year.
Pruning and Training Fruit Trees
If you didn’t get around to pruning your fruit trees in winter, April is your last chance before the trees come into full leaf. Focus on removing any dead, damaged, or crossing branches to improve air circulation and light penetration. For trained forms such as espaliers or cordons, continue to tie in new growth to their supports and maintain their shape.
Feeding and Mulching
Fruit trees and bushes are hungry plants, so it’s important to feed them in April to support their growth and fruit production. Apply a balanced fertiliser or a specific fruit fertiliser around the base of each plant. After feeding, mulch with organic material such as compost or well-rotted manure. Mulching helps retain moisture, suppress weeds, and improve soil structure. Be sure to keep the mulch away from the base of the plants to prevent rot.
Protecting Blossoms from Frost
April can still bring frosty nights, which can damage the delicate blossoms of fruit trees and bushes. To protect your blossoms, cover the plants with horticultural fleece or old sheets on nights when frost is forecast. This is especially important for tender fruits like peaches and apricots, which are more susceptible to frost damage. If you have fruit trees in pots, consider moving them to a more sheltered spot during cold spells.
Houseplants
Houseplants bring greenery and life into the home, and April is a great time to give them some extra care and attention.
Repotting and Feeding
April is the ideal time to repot any houseplants that have outgrown their pots. Choose a pot that is one size larger than the current one, and use a good quality potting mix appropriate for the plant. Gently remove the plant from its old pot, loosen the roots, and place it in the new pot with fresh compost. Water well after repotting, and apply a balanced liquid fertiliser to encourage healthy growth.
Managing Light and Watering
As the days get longer and brighter, your houseplants will need more light to thrive. Move them to a spot where they can get plenty of indirect sunlight, but be careful not to place them in direct sunlight, which can scorch their leaves. Watering needs will also increase as the weather warms up, so check the soil regularly and water when the top inch is dry. Be sure to avoid overwatering, as this can lead to root rot.
Pest Control
Houseplants can be susceptible to pests such as aphids, spider mites, and mealybugs, especially as the weather warms up. Check your plants regularly for any signs of pests, and deal with them promptly using insecticidal soap or neem oil. For larger infestations, you may need to quarantine the affected plant to prevent the pests from spreading to your other plants.
Patios
A well-maintained patio can be an extension of your living space, providing a place to relax, entertain, and enjoy the garden. April is the time to get your patio ready for the summer months.
Cleaning and Repairing Patios
Winter can leave your patio looking dirty and neglected, so start by giving it a good clean. Sweep away any leaves and debris, and then use a pressure washer or stiff brush to remove any dirt, algae, or moss from the surface. If your patio has cracks or loose paving stones, now is the time to repair them. Use a suitable filler for cracks, and re-lay any loose stones with fresh mortar or sand.
Container Gardening
April is the perfect time to start planting up containers for your patio. Choose a mix of flowering plants, herbs, and small shrubs to create a colourful and fragrant display. Use good quality compost and ensure that your containers have adequate drainage. Water your containers regularly, especially in warm weather, and feed them with a liquid fertiliser every couple of weeks to keep the plants healthy and blooming.
Conclusion
April is a month of renewal and growth in the UK garden. With the right care and attention, your garden will burst into life, providing a beautiful and bountiful space for you to enjoy throughout the year. From lawns and roses to vegetables and houseplants, there’s plenty to keep you busy in the garden this month.
