Growing strawberries through a mild Spanish winter

Strawberries are one of the few soft fruits that genuinely suit a Costa Blanca garden, provided the planting is timed for the local climate rather than a northern European one. The plant sold as a strawberry is Fragaria × ananassa, a hybrid of two American species, and modern low-chill cultivars have been bred for exactly the mild winters found along this coast.

Huelva is the centre of Spain's commercial strawberry crop. Local gardens are not Huelva, but the commercial method points the way: plants go in during autumn, not spring, so the roots establish through the cool months and crop before the summer heat checks growth.

Choosing plants

Buy certified virus-free plants from a garden centre or nursery. Strawberry yields often decline after two or three years as plants age and viruses accumulate, so use runners only from healthy young stock. Two broad types are worth knowing. June-bearing cultivars fruit heavily over a few weeks in late spring. Perpetual or day-neutral cultivars produce smaller flushes over a longer season, pausing in the hottest weeks. Ask a local supplier for low-chill cultivars suited to mild winters rather than relying on a variety list written for another climate.

When and where to plant

Plant in autumn, usually during October or November once the fiercest heat has passed. Aim for a raised bed or large container with free-draining soil enriched with compost, because heavy or permanently wet ground causes crown rot. On limestone soil a container filled with a loam-based mix is often more reliable than fighting the native pH.

Set plants so the crown sits exactly at soil level, neither buried nor lifted clear. Space them around 30 centimetres apart. A position with morning sun and shade from the fiercest afternoon light in July and August will keep the plants cropping longer than an open south-facing spot.

Watering and feeding

Strawberries are shallow rooted and need steady moisture, which makes drip irrigation with a timer the sensible approach. Mulch with straw or a woven mat to keep fruit off the soil, conserve water and keep the root zone cooler. Feed with a high-potassium liquid feed every couple of weeks once flowering starts and ease off once the main crop is picked.

Runners and replacement

Plants send out runners through summer. Remove most of them to keep the parent cropping, or peg a few down into small pots to raise replacements. Productivity falls after the second or third year, so replace a third of the bed each autumn from healthy runners or fresh certified stock and the patch stays young.

Common problems

Birds are the main threat to ripening fruit and netting is the only dependable answer. Snails and slugs climb into the crop after rain or irrigation. Red spider mite appears in hot dry air and shows as fine pale speckling on the leaves; raising humidity around the plants and avoiding drought stress reduces it. Grey mould rots fruit in still, humid conditions, so space plants for airflow and pick regularly.
