How to Grow Strawberries at Home: From Planting to Harvest

Choosing the right type

Strawberry varieties fall into three main groups, and choosing the right one shapes your harvest:

• June-bearing (summer-fruiting): one large crop over two to three weeks in early summer; best flavor and highest single yield
• Everbearing: two or three smaller crops through summer and early autumn
• Day-neutral: fruit continuously from early summer to the first frosts as long as temperatures are mild
• Alpine strawberries: tiny, intensely flavored berries; tolerate partial shade and grow well from seed

Where to plant

Strawberries need at least six to eight hours of direct sun a day to produce sweet fruit. They like rich, well-drained soil that is slightly acidic (pH around 5.5–6.5). Heavy clay soils can cause root rot, so improve them with plenty of compost or grow in raised beds.

Avoid planting where tomatoes, potatoes, peppers or eggplants grew in the last few years, as these crops can share soil diseases such as verticillium wilt.

Planting step by step

Most home gardeners start with bare-root plants or young potted plants rather than seed:

• Plant in early spring, or in late summer for a crop the following year
• Dig in a bucket of compost per square meter
• Space plants 30–45 cm apart in rows 75 cm apart, or closer in raised beds
• Set the crown — where the leaves meet the roots — exactly at soil level; too deep causes rot, too shallow dries the roots
• Water well after planting and keep the soil moist for the first few weeks

Growing in containers

Strawberries are ideal for pots, troughs, grow bags and hanging baskets, which also keep fruit away from slugs. Use a container at least 20 cm deep with drainage holes, and fill it with good-quality peat-free potting compost. A 30 cm pot holds about three plants.

Containers dry out quickly, especially in summer, so check daily and water whenever the top few centimeters of compost feel dry. Feed every 10–14 days with a high-potash liquid fertilizer, such as tomato feed, once flowers appear.

Watering, feeding and mulching

Consistent moisture is the key to plump berries. Water at the base of the plant in the morning rather than over the leaves, which helps prevent fungal disease. Around 2.5 cm of water a week is a good guide in open ground, more during hot spells.

Once small fruits begin to form, tuck straw, or a strawberry mat, under the plants. This mulch keeps berries clean, off damp soil and less prone to rot — and is how the plant is thought to have got its name.

Protecting your crop

Everyone loves strawberries, including wildlife. Common problems and solutions:

• Birds: cover plants with fine netting supported on hoops once fruits start to color
• Slugs and snails: use wildlife-friendly traps, copper tape on pots, or hand-pick in the evening
• Gray mold (botrytis): improve air flow, remove damaged fruit, and avoid wetting the berries
• Frost: cover early flowers with horticultural fleece on cold nights — frost turns the flower center black and it will not fruit

Harvesting

Pick strawberries when they are fully red all over, ideally in the morning when they are cool. Hold the stem rather than the fruit and snap it just above the berry, leaving the green cap on — this keeps them fresh longer. Check plants every day or two during the season; ripe berries left on the plant quickly attract pests and rot.

Do not wash berries until you are ready to eat them. Homegrown strawberries are best eaten within a day or two, and any surplus can be frozen.

Runners and renewing plants

After fruiting, plants send out long stems called runners, which root to form new plants. Peg a few healthy runners into small pots of compost and cut them from the parent once rooted to create free replacement plants. Remove other runners so the main plant puts its energy into next year's crop.

Strawberry plants are most productive for about three years. Replacing a third of your plants each year with rooted runners keeps your patch vigorous and productive.
