Growing Strawberries in Containers: A Complete How-To Guide

You don’t need a garden bed, an allotment, or even much space to grow brilliant strawberries. In fact, growing strawberries in containers can actually give you better results than growing them in the ground — fewer slugs, no soil-borne diseases, and you can move them to catch the sun.

I started growing container strawberries because I had more patio than garden, and within a couple of seasons I was picking enough to keep the family in strawberries through June and July. Here’s everything I’ve learned about getting the best harvest from pots, planters, and hanging baskets.

Why Containers Are Actually Better for Strawberries

This might sound counterintuitive, but strawberries genuinely thrive in containers. Here’s why:

• Slug and snail control — raised containers are much harder for slugs to reach than ground-level plants. This alone can double your harvest in a damp UK garden.
• Better drainage — strawberries hate sitting in waterlogged soil. Containers with drainage holes let excess water escape freely.
• Warmer roots — containers warm up faster in spring than garden soil, giving your plants a head start.
• No soil diseases — strawberries are prone to verticillium wilt and red core disease in garden soil. Fresh compost in a container eliminates this risk.
• Mobility — you can move containers to follow the sun, bring them under cover during heavy rain, or shift them to a sheltered spot over winter.
• Space efficiency — a tiered strawberry planter on a patio takes up less than half a square metre and can hold 15-20 plants.

Choosing the Right Container

Almost anything that holds compost and has drainage holes will grow strawberries, but some containers work noticeably better than others.

Traditional Pots

Standard terracotta or plastic pots work perfectly well. Use pots at least 25-30cm in diameter and 20cm deep. You can fit 3-4 plants per 30cm pot. Terracotta looks better but dries out faster — you’ll need to water more frequently. Plastic retains moisture longer, which is an advantage in summer.

Tip: Put a layer of crocks (broken pot pieces) or gravel in the bottom of each pot to prevent the drainage holes clogging with compost.

Strawberry Planters (Tiered)

Tiered or tower planters are specifically designed for strawberries, with planting pockets at different heights. They’re space-efficient and look attractive on a patio. A three-tier planter can hold 12-15 plants in a 40cm footprint.

The downside is watering — the top tier gets water first, and the lower pockets can dry out if you’re not thorough. Water slowly and check the bottom tiers are getting enough moisture.

Hanging Baskets

Strawberries are excellent in hanging baskets. The fruit hangs down over the edge, keeping it clean and away from slugs entirely. Use a 35cm basket lined with sphagnum moss or a coir liner, and plant 4-5 plants per basket.

The challenge with hanging baskets is watering — they dry out incredibly quickly in summer. You may need to water twice a day during hot spells. A self-watering basket or adding water-retaining gel to the compost helps enormously.

Grow Bags

Standard tomato grow bags work for strawberries, and they’re cheap. Cut three or four planting holes in the top, and you’re ready to go. They’re not the prettiest option, but they’re practical for a first season while you work out how many plants you want to commit to.

Fabric grow bags (the felt-type ones) are a step up — they breathe better, prevent root circling, and look more presentable. A 40-litre fabric bag holds 6-8 plants comfortably.

Best Strawberry Varieties for Containers

Not all strawberry varieties perform equally well in containers. You want compact growth habits, good disease resistance, and ideally varieties bred for pot culture. Here are the best types for UK container growing:

My recommendation: Grow a mix of June-bearing and everbearing varieties. The June-bearers give you a heavy glut for a few weeks (perfect for jam-making), while the everbearers keep producing smaller quantities through the whole summer. A combination of Cambridge Favourite and Flamenco covers both bases nicely.

Planting and Positioning

Getting the planting right sets you up for the whole season.

Compost: Use a good-quality multi-purpose compost mixed with about 20% perlite for drainage. Strawberries want well-drained but moisture-retentive soil — soggy roots rot quickly. Avoid using garden soil in containers; it compacts and drains poorly.

Planting depth: This is critical. The crown of the plant (where the stems emerge from the roots) must sit at soil level — not buried, not exposed. Bury the crown and it rots. Leave it too high and the roots dry out. Look for the point where the roots start and plant to exactly that depth.

Spacing: In containers, plant strawberries 20-25cm apart. This is tighter than ground planting because you’ll be removing runners (more on that below) rather than letting them spread.

Position: Strawberries want at least 6 hours of direct sunlight daily. A south or west-facing position is ideal in the UK. They’ll tolerate some shade but you’ll get fewer, less sweet fruit. The beauty of containers is you can experiment — move them around until you find the sunniest spot.

When to plant: Bare-root strawberry plants go in during March–April. Potted plants can be planted any time from spring through early summer. Avoid planting in the heat of mid-summer unless you can water very frequently.

Watering and Feeding Schedule

Watering is the single most important factor for container strawberries. Unlike ground-planted strawberries, they can’t send roots deep to find moisture — they’re entirely dependent on you.

Watering guidelines:

• Spring (March–May): Water when the top 2cm of compost feels dry. Usually every 2-3 days.
• Flowering and fruiting (May–August): Water daily. In hot spells, you may need to water morning and evening, especially hanging baskets and small pots.
• Autumn (September–November): Reduce to every 3-4 days. The plants are winding down.
• Winter: Only water if the compost is completely dry. Overly wet compost in winter causes root rot.

Water at the base of the plant, not over the leaves and fruit. Wet fruit rots faster, and wet leaves encourage fungal diseases like grey mould (botrytis).

Feeding:

• Start feeding when the first flowers appear, usually late April or May.
• Use a high-potash liquid feed (a tomato feed works perfectly — strawberries and tomatoes have similar nutritional needs) every 10-14 days.
• Stop feeding once the main harvest is over for June-bearing varieties. Continue feeding everbearing varieties until September.

Managing Runners

Strawberry plants send out long stems called runners, which produce baby plants at their tips. In a garden bed, this is how strawberries spread. In containers, runners divert energy away from fruit production.

The rule: During the fruiting season, remove runners as soon as they appear. Snip them off close to the parent plant with scissors or secateurs. This directs all the plant’s energy into producing fruit rather than babies.

Exception: In late summer (August–September), let a few runners develop if you want free new plants for next year. Peg the runner tip into a small pot of compost next to the parent plant. Once it’s rooted (2-3 weeks — give it a gentle tug to check), cut it from the parent. You now have a new strawberry plant at zero cost.

Strawberry plants are productive for about 3-4 years. After that, yields decline noticeably. Using runners to propagate new plants keeps your supply going indefinitely without buying new stock.

Protecting from Pests (Especially Birds and Slugs)

You’re not the only one who wants your strawberries. Birds and slugs are the two biggest threats, and if you don’t protect your crop, they’ll eat the lot before you pick a single berry.

Birds: Blackbirds in particular are strawberry specialists. They’ll wait until the fruit is perfectly ripe and strip a plant overnight. The only reliable solution is netting. Drape fine-mesh bird netting over your containers, supporting it on canes or a small frame so it doesn’t rest on the fruit. Make sure the edges are secured — birds are persistent and will find gaps.

Slugs and snails: Containers already reduce slug damage dramatically, but they’re not immune. Copper tape around the rim of pots creates a barrier slugs dislike crossing — the copper gives them a mild electric-like sensation. Wool pellets or sharp grit around the base of plants also helps. Organic slug pellets (ferric phosphate-based) are safe for wildlife and effective as a backup.

Grey mould (botrytis): This fungal disease turns fruit soft and grey, especially in wet weather. Prevent it by ensuring good air circulation between plants, removing any rotting fruit immediately, and watering at the base rather than overhead.

Aphids: Check under leaves regularly. A strong jet of water from a hose knocks most aphids off. For persistent infestations, an organic insecticidal soap spray works well without harming pollinators.

Overwintering Your Container Strawberries

Strawberries are perennial — they come back year after year. But container plants are more vulnerable to winter cold than ground-planted ones because the roots are exposed above ground level and can freeze solid.

In most of the UK (zones 8-9):

• Move containers against a house wall or into a sheltered spot. The house radiates warmth and provides some frost protection.
• In severe frosts (below -5°C for extended periods), wrap pots in bubble wrap or hessian to insulate the roots.
• Remove any dead or yellowing leaves, but don’t cut back the crown — the plant needs its growing point intact.
• Reduce watering to occasional — just enough to prevent the compost from going bone dry.
• Don’t feed over winter. The plants are dormant and don’t need nutrients until spring.

Replacing compost: Every spring, scrape off the top 5cm of old compost and replace it with fresh, mixed with a handful of slow-release fertiliser granules. Every 2-3 years, repot completely with fresh compost. This prevents nutrient depletion and disease buildup.

Yield Expectations — How Many Plants Do You Need?

Realistic yields depend on variety, care, and weather, but here are some ballpark figures:

For a family of four who enjoy fresh strawberries through the summer, I’d suggest 20-25 plants total — a mix of about 10 June-bearing for the main glut and 12-15 everbearing for the long season. That sounds like a lot, but they fit comfortably in a couple of tiered planters and a few hanging baskets.

If you want enough for jam-making, double the June-bearing plants. You need roughly 1kg of strawberries per jar of jam, so a dozen plants will give you 3-5 jars depending on the season.

Recommended Products for Container Strawberries

Here’s what I’d put together as a complete container strawberry growing kit:

Containers:

• A three-tier strawberry planter for the main crop (holds 12-15 plants in minimal space)
• A couple of 35cm hanging baskets for additional plants and a decorative display
• Coir basket liners and water-retaining gel crystals for the hanging baskets

Growing supplies:

• Multi-purpose compost (a 70-litre bag fills a tiered planter and several pots)
• Perlite for drainage (mix about 20% into your compost)
• Slow-release fertiliser granules for spring top-dressing
• Liquid tomato feed for the growing season

Protection:

• Fine-mesh bird netting and support hoops
• Copper tape for slug deterrence
• Organic slug pellets as a backup

Plants:

Order bare-root plants in early spring for the best value (usually half the price of potted plants). A mix of 10 Cambridge Favourite and 10 Flamenco will give you a solid June glut and summer-long picking for a family.

Growing strawberries in containers is one of the most rewarding things you can do with a small outdoor space. There’s genuinely nothing like picking warm, ripe strawberries from your own patio in June. Start with a few plants this year and you’ll be expanding your collection by next season — I guarantee it.
