🌱 What to Sow in February for Autumn Harvests

February sowing isn’t just about early spring crops — it’s also about setting up vegetables that will be harvested in autumn and even winter. Crops that need a long growing season benefit hugely from an early, slow start now.

The key is choosing vegetables that establish roots early and grow steadily over many months.
