Soil Preparation
For the best spinach, incorporate generous amounts of garden compost into the bed the previous autumn. Spinach needs a rich, moisture-retentive soil to grow quickly and avoid bolting.Sowing
Sow thinly, direct in the ground. Spring sowings will produce through early summer; late summer and autumn sowings crop through winter and early spring when the hungry gap is approaching.Preventing Bolting
Spinach runs to seed quickly in heat. Choose bolt-resistant varieties for spring sowing, and keep well watered in dry spells. Summer sowings in partial shade can extend the season.Soil: Rich, moisture-retentive loam with plenty of added compost. Avoid sandy, dry soils.
