How to grow your own strawberries

Strawberries are one of the easiest fruits to grow at home, whatever the space available to you. Whether you have a greenhouse, vegetable patch, hanging basket, pots on the patio or even a simple window box, strawberries are incredibly versatile and rewarding to grow. Experience the quintessential taste of summer in your own garden with our step-by-step guide.

• When to plant: March / April / October
• When to harvest: June /July / August
• Ready in: up to 12 weeks
• Challenge level: a doddle

For a great yield of the best-tasting strawberries, plant in the spring or autumn. Strawberries can be grown in a wide range of soils, from light sand to heavy clay but ideally in well-drained, fertile soil. Strawberries love the sun and prefer to be sheltered from the wind. Avoid areas susceptible to frost and soil that is prone to the disease verticillium wilt (where potatoes, chrysanthemums or tomatoes have previously grown).

Once you have identified the perfect spot for growing strawberries, prepare the soil by digging over, removing any perennial weeds and adding organic matter such as compost or well-rotted manure. If your soil is poor then try a slow-release organic fertiliser in the spring.

Traditionally, strawberries are grown directly in the garden soil, planted in rows. Place the strawberry plants every 35cm/13 inches in rows that are 75cm/30 inches apart. Plant with the crown at soil level and cover with a net to prevent birds and squirrels eating the fruit. For an earlier crop, grow strawberries under a tunnel cloche which should be removed when the plants start flowering.

As the fruits develop, place dry straw or mulching fabric underneath to prevent them blemishing or rotting.

During the growing season, give strawberry plants a boost with tomato feed every 10 days or so and water frequently while new plants are establishing and during hot, dry weather. In a heated greenhouse or conservatory, strawberries will flower much earlier provided the temperature does not exceed 16°C (61°F). You should be able to enjoy crops for three years before needing to replace your strawberry plants.

If you would like to try growing strawberries from seed, this gives you many more options to grow unusual varieties that look beautiful as hanging baskets. Strawberry seeds will take up to a month to germinate with the first fruit appearing the following year.

Once strawberry cropping has finished, remove old leaves and straw mulch. We recommend you rotate strawberry beds every three years to minimise the risk of disease and damage from pests. Continue to feed and water your strawberry plants well and leave nets off to allow the birds to pick off pests.

As the summer progresses, keep on top of weeding and continue to remove runners and dead foliage. Spread a general purpose fertiliser around your plants every spring along with a mulch of well-rotted manure or compost.

To propagate your strawberries, peg down the runners (trailing stems) in June or July while attached to the mother plant. Eventually they will form a new plant (no more than five per mother plant). By August, runners should be well established and can be cut away from the parent ready for transplanting.

Pick any ripe strawberries straight away to prevent rotting (plants will need to be checked every other day during this period). The fruit is ready when it has turned red, although different varieties may have slightly different shades. Pick gently to avoid bruising and make sure the green stalk remains with the fruit.

• Birds: Protect plants from birds with netting or a horticultural fleece.
• Powdery Mildew (a white powdery deposit over the leaf surface): keep soil moist.
• Grey Mould (a fuzzy grey mould on buds, leaves, flowers or fruit that causes collapsed seedlings and shrivelling): Remove infected parts immediately and plant further apart.
• Fungal Leaf Spot (purple or brown spots with a yellow ring): Remove affected leaves and ventilate covered crops.

• Vine Weevil (notches on the edge of leaves and damage to roots caused by white larvae with brown heads): Apply chemical control as a liquid drench applied to the compost or the biological control, nematode Steinernema Kraussei.
