What Are Strawberry Marshmello Plants?
Strawberry Marshmello plants are a main-season variety bred for their exceptional sweetness and large fruit. First developed at East Malling Research in Kent, they are ideal for gardeners looking for strong, disease-resistant plants. The large, crowned plants produce abundant fruit with a soft texture, making them a standout in any strawberry patch.

The flavour alone is reason enough to choose Strawberry Marshmello. These are some of the sweetest strawberries you will ever taste, making them ideal for fresh eating, desserts, and jams. Beyond flavour, Marshmello strawberry plants are strong and vigorous, with excellent disease resistance.
If you’re short on space, this variety thrives in containers and hanging baskets. The plants also boast a long shelf life, ensuring your freshly picked fruits stay in perfect condition. Their mid-season fruiting period offers a reliable and productive addition to your gardening schedule.
What Is the Best Time to Plant Marshmello Strawberries?
Strawberry Marshmello is best planted in late autumn or early spring when the soil is moist and workable. This timing ensures strong root development and new growth when the weather warms up for bare-root plants.
Ensure the soil is well-drained and enriched with organic matter, such as well-rotted manure or compost. Avoid planting during frosty conditions, as young roots need to establish without stress.
How Do You Plant Strawberry Marshmello?
Begin by preparing a sunny, sheltered spot in your garden or selecting containers with free-draining soil. If planting in rows, space each strawberry plant 45cm apart, leaving 75cm between rows. This spacing allows ample airflow and prevents diseases like rot or grey mould.
For bare-root plants, place them in the soil at a level where the crown is just above the surface. Gently firm the soil around the roots and water thoroughly. For container gardening, choose a specially designed planter with good drainage.
What Are the Ideal Growing Conditions?
Strawberry Marshmello thrives in a sunny position with free-draining, well-manured soil. Keeping the soil moist but not waterlogged is key to healthy plants. Avoid planting in areas prone to waterlogging, leading to root diseases.
Consider growing your Marshmello plants in a greenhouse or polytunnel in colder climates to extend the growing season. With proper care, the plants will reward you with heavy yields of large, juicy fruits.
How to Care for Marshmello Strawberry Plants
Caring for Marshmello strawberry plants is simple, but attention to detail makes all the difference. Regularly remove any weeds around each plant to reduce competition for nutrients. Applying mulch around the base of the plants helps retain moisture and keeps the soil temperature consistent.
Feed your plants with a liquid fertiliser every 14 days during the growing season. For runners, trim them back to focus the plant’s energy on fruit production. In late autumn, prune the foliage to encourage healthy new growth the following spring.
Dealing with Pests and Diseases in Marshmello Plants
Strawberry Marshmello is a robust variety with strong resistance to many common diseases, including verticillium wilt and powdery mildew. However, it’s still important to remain vigilant against pests such as slugs, snails, and aphids, which can damage foliage and reduce yields.
To protect your plants, use organic slug pellets to deter slugs and snails, especially in damp conditions. These are safe for wildlife and effective when applied around the base of the plants. For aphids, which tend to gather on new growth, insecticidal soap controls infestations without harming beneficial insects.
Good garden hygiene also plays a key role—space your plants well to allow air circulation, and avoid overhead watering to reduce the risk of grey mould (Botrytis). Regularly check your plants for early signs of pests or disease and act quickly to keep your Marshmello strawberries healthy and productive.
When and How to Harvest Marshmello Strawberries
Marshmello strawberries are typically ready to pick in the main season, with fruiting beginning in late spring or early summer. The fruits are dark red, sweet, and juicy, making them a treat to harvest.
Pick the strawberries when fully ripe and detach easily from the stem. Handle them gently to avoid bruising and place them in a shallow container to maintain their freshness. With proper care, your plants will produce heavy yields throughout the season.
How to Enjoy the Superb Flavour of Marshmello Strawberries
The exquisite flavour of Marshmello strawberries makes them perfect for eating fresh or creating delicious desserts. Add them to a fruit salad, blend them into smoothies, or make your own jam. Their soft texture and sweetness also make them ideal for freezing, so you can enjoy the taste of summer all year round.
For the ultimate indulgence, serve your Marshmello strawberries with a dollop of cream or melted chocolate. The possibilities are endless, and each bite reminds you why this variety is so highly prized.
