How to grow strawberry
Overview
Strawberry (Fragaria x ananassa) is a hybrid perennial grown for its sweet, aromatic fruit. It is a favourite in home gardens for its superior flavour compared to store-bought berries, but requires regular renewal of plants and careful soil management to avoid disease.
Varieties
- Albion — A day-neutral variety producing firm, sweet fruit from spring to autumn, popular in temperate and subtropical zones.
- Camarosa — A short-day variety with large, glossy berries, ideal for cool and temperate climates.
- Fragaria x ananassa 'Hokowase' — A New Zealand-bred variety with excellent flavour and good disease resistance.
Soil Preparation
Strawberries prefer slightly acidic soil (pH 6.0–6.5) with good drainage. Improve heavy clay with compost or raised beds. Add a balanced fertiliser before planting, and top-dress with compost annually.
Growing Guide
Plant strawberries in a sunny, well-drained position with plenty of organic matter worked into the soil. Space plants 30–40 cm apart in rows or mounds, with crowns at soil level. Water at the base to keep leaves dry and reduce fungal issues. Mulch with straw or pine needles to suppress weeds and keep fruit clean. Replace plants every 2–3 years to maintain vigour.
Care
Feed strawberries with a balanced fertiliser (e.g., 10-10-10) every 4–6 weeks during growth, switching to a high-potash feed as fruit sets. Remove runners to focus energy on fruiting, unless you want to propagate new plants. Replace plants every 2–3 years to prevent decline.
Companion Planting
Grow strawberries with borage, which attracts pollinators and may improve flavour, and with lettuce or thyme, which share similar moisture needs. Avoid planting near brassicas or potatoes, which can compete or harbour shared pests.
Common Pests & Risks
Slugs and snails are the main pest; use iron-based baits or traps. Aphids and mites can be hosed off or controlled with insecticidal soap. Birds are a problem in some areas; netting is the most reliable solution. Fruit rot (Botrytis) is reduced by good air flow and avoiding wet foliage.
Harvesting
Harvest strawberries when the fruit is fully red, including the tip, and still firm. Pick with the stalk attached to keep fruit fresh longer. Check plants daily during peak ripening, as berries spoil quickly on the ground.
In the Kitchen
Strawberries are best eaten fresh, but also suit jams, desserts, and freezing. Store unwashed in the fridge for 2–3 days. Wash just before use.
Troubleshooting
Yellow leaves: often due to nitrogen deficiency; feed with a balanced fertiliser. Brown leaf edges: may be salt burn from over-fertilising; flush soil with water. Small fruit: caused by lack of water or poor pollination; water consistently and plant near flowers. Grey mould on fruit: Botrytis; improve air flow and remove affected berries. Stunted growth: check for root rot in wet soil; improve drainage.
