Spinach Planting Program

Seeding for spinach for winter production occurs during the warmest weeks of the year, which is often the most challenging time to sow and grow spinach.

Keep the soil moist and cool. Keeping the soil moist and cool will help prevent early bolting and is often best sown in the cooler areas of the allotment or garden and avoid greenhouse sowings at all costs.
