Spinach Succession Planting & Season Extension

Johnny’s Planting Programs are designed to take the guesswork out of succession planting, allowing you to easily extend your harvest throughout the growing season. Slow-growing spinach varieties mature best under warm conditions, whereas faster-growing varieties mature best under cooler conditions.

Tech Tip

In the North, spinach can be grown in a hoophouse right through December. The key is to have the spinach established before the day length drops below 10 hours, after which growth rate slows to a standstill but tolerance to cold temperatures remains in effect, allowing for winter harvest and overwintering for early spring harvest.
