Soil & site
Rich, nitrogen-heavy soil, pH 6.5–7.5 — spinach sulks in acidic beds.
Seedling care
Seed germinates poorly above 75°F soil. For late-summer sowing, pre-chill seed in the fridge for a week and sow in evening shade.
Growing notes
The hardiest green here. Rows 12 in apart.
Harvest
Take outer leaves from 6 weeks on. Under a low tunnel it overwinters and explodes with growth in February.
