Strawberries are the quintessential taste of British summer, and growing your own sweet, juicy berries is one of gardening's greatest pleasures. Their vibrant red colour and irresistible flavour make them a must-have for any fruit patch or container garden.
Achieving a continuous and abundant harvest of strawberries in the UK largely depends on understanding the optimal planting times and the different types of plants available. Whether you dream of a single, massive crop for jams or a steady trickle of berries for desserts, timing is everything.
In this comprehensive guide, we'll walk you through the best times to plant strawberries in the UK, covering bare-root runners, plug plants, and the nuances of different varieties, ensuring your efforts yield a truly sweet reward.
Quick Answer: When Can You Grow Strawberries?
In the UK, the best time to plant bare-root strawberry runners is from late July to September for a full harvest the following summer. Plug plants can be planted from spring (March-April) onwards, while alpine and everbearing varieties offer more flexibility for spring and summer planting.
Strategic planting ensures a continuous supply of delicious, home-grown strawberries.
Strawberry Growing Timeline in the UK
Late July – September: The Best Time for Bare-Root Runners
This autumn window is widely considered the best time to plant bare-root strawberry runners in the UK. Planting now allows the plants to establish a strong root system before winter sets in.
- Conditions: Soil is still warm from summer, but moisture is usually more consistent.
- Benefits: Plants establish well and grow vigorously the following spring, producing a full crop of fruit in their first year.
- Method: Plant into well-prepared soil, ensuring the 'crown' (the central growing point) is level with the soil surface. Space plants 30-45cm apart.
Bare-root runners are often available from garden centres or online nurseries during this period.
March – April: Spring Planting
Spring is another popular time to plant strawberries, particularly for plug plants or cold-stored bare-root runners. While spring-planted strawberries may yield a small crop in their first year, their main harvest will be from their second year onwards.
- Conditions: Plant once the soil is workable and the risk of severe frost has passed.
- Benefits: Good for filling gaps or starting a new bed if autumn planting wasn't possible.
- Method: Plant as with autumn planting, ensuring consistent watering as they establish.
Plug plants (small plants already growing in compost) are readily available in spring and establish quickly.
May – June: Perpetual & Alpine Strawberries
While not ideal for traditional June-bearing varieties, May and June are suitable months for planting perpetual (everbearing) strawberries or alpine strawberries.
- Everbearing/Perpetual: These varieties produce smaller crops continuously from late spring until the first frosts. Planting now allows them to establish for summer and autumn fruiting.
- Alpine Strawberries: These charming, small-fruited plants are less demanding and can be planted or sown from seed throughout spring and early summer for continuous tiny, flavourful berries.
Ensure good watering during hot weather for new plantings.
Harvesting Your Strawberries
- June-Bearing: Typically provide one main, heavy crop over 2-3 weeks in June or early July, depending on the variety and location.
- Everbearing/Perpetual: Produce smaller flushes of fruit from May/June right through to the first autumn frosts.
- Alpine: Yield tiny, intensely flavoured berries continuously from late spring until autumn.
Harvest regularly when the berries are fully red, firm, and sweet. Pick in the morning after dew has dried but before the heat of the day.

Key Factors for Successful UK Strawberry Growing
Choosing the Right Variety
- June-bearing (Summer-Fruiting): Produce one large crop. Best for processing (jam, freezing). E.g., 'Cambridge Favourite', 'Elsanta', 'Symphony'.
- Everbearing / Perpetual: Produce smaller, continuous crops. Best for fresh eating. E.g., 'Finesse', 'Mara des Bois', 'Flamenco'.
- Alpine Strawberries: Small, intensely flavoured, great for pots/borders. E.g., 'Mignonette', 'Reine des Vallées'.
Site and Soil Preparation
- Sunny Location: Strawberries need at least 6-8 hours of direct sun daily for the sweetest, most abundant fruit.
- Well-Drained, Fertile Soil: They thrive in rich, slightly acidic to neutral soil (pH 6.0-6.5). Amend heavy clay with compost and grit. Avoid recently manured ground to prevent excessive leaf growth and 'dirty' tasting fruit.
- Crop Rotation: Avoid planting in a spot where strawberries (or other members of the rose family) have grown in the last 3-4 years to prevent soil-borne diseases.
Planting Material: Runners, Plugs, or Bare-Roots
- Bare-Root Runners: Dormant plants, usually supplied in autumn. Cost-effective for large plantings. Soak roots before planting.
- Plug Plants: Small plants already growing in compost, supplied in spring. Establish quickly.
- Container-Grown: Available year-round, but spring/autumn planting is still best for establishment.
Watering and Feeding
- Consistent Moisture: Crucial during establishment, flowering, and fruit development. Inconsistent watering can lead to small, hard berries.
- Feeding: Feed with a balanced fertiliser in spring, then switch to a potash-rich feed once flowers appear to encourage fruiting.
Mulching for Cleanliness & Pest Control
- Straw: Apply a layer of straw around plants as flowers begin to form. This keeps berries clean, suppresses weeds, and deters slugs/snails. This is where 'straw'berry gets its name!
Runner Management
Strawberry plants send out 'runners' – new plants on long stems. While these can be used to propagate new plants, allowing too many to grow saps energy from the main plant, reducing fruit production. Snip off unwanted runners as they appear.
Pest and Disease Prevention
- Slugs and Snails: Attracted to ripening fruit. Mulching with straw, using copper tape, or organic pellets can help.
- Birds: Love strawberries! Netting is the most effective deterrent once fruits begin to ripen.
- Grey Mould (Botrytis): A fungal disease in damp conditions. Ensure good air circulation, remove diseased leaves/fruit promptly.
Common Strawberry Growing Mistakes in the UK
Planting Too Deep or Too Shallow
The crown must be at soil level. Too deep buries the crown and causes rot; too shallow exposes roots and dries out the plant.
Not Mulching with Straw
Leaving berries to touch the soil makes them vulnerable to slugs, mould, and dirt. Straw is a simple, effective solution.
Forgetting Pest and Bird Protection
The moment your berries show colour, they become a target. Neglecting protection can mean losing your entire crop.
Allowing Too Many Runners to Grow
While good for propagation, excessive runners divert energy from fruit production. Snip them off regularly unless you actively want new plants.
Over-fertilising with Nitrogen
Too much nitrogen encourages lush leafy growth but at the expense of flowers and fruit. Opt for balanced feed in spring, then potash-rich feed for fruiting.

Frequently Asked Questions
What is the best time to plant strawberries in the UK?
Late summer to early autumn (July-September) is ideal for planting bare-root strawberry runners. This allows them to establish strong roots over winter for a fantastic crop the following June. Spring (March-April) is also suitable, especially for plug plants, though their first-year yield will be smaller.
Should I plant June-bearing or everbearing strawberries?
It depends on your goals! June-bearing (also called summer-fruiting) varieties produce one large crop in early summer, perfect if you want a lot of berries for jams, freezing, or a big family feast. Everbearing (or perpetual) varieties produce smaller, continuous crops from late spring right through to autumn, ideal for having fresh berries for daily eating.
How often do strawberry plants need replacing?
Strawberry plants are most productive for about 3-4 years. After this, their yields typically start to decline, and they become more susceptible to diseases. It's a good practice to start new plants from healthy runners or purchase fresh stock every few years to maintain productivity.
Why are my strawberries being eaten by slugs and birds?
Slugs and snails are attracted to ripe berries, especially those lying directly on the soil. Mulching with straw around your plants helps lift the berries off the ground and creates a drier surface, deterring slugs. For birds, netting placed over the plants as soon as the fruits begin to colour is the most effective deterrent.
Can I grow strawberries in containers?
Yes, absolutely! Strawberries are excellent candidates for containers, hanging baskets, and dedicated strawberry planters. Growing them in pots allows for easier management of pests like slugs, extends your growing space, and keeps the berries wonderfully clean. Everbearing varieties are particularly well-suited to container life.
Final Thoughts
Growing your own strawberries in the UK is a delightful and rewarding experience, offering the unmatched taste of truly fresh fruit. The success of your strawberry patch hinges on choosing the right varieties and, crucially, understanding the optimal times for planting.
