Understanding Colorado’s Planting Zones
Colorado’s diverse landscape means different areas experience varying growing seasons. Knowing your specific planting zone, which ranges from 3 to 7, is essential for determining when to plant lettuce. Lower zone numbers indicate colder climates with shorter growing seasons, while higher zone numbers signify milder winters and longer growing seasons. You can determine your planting zone by consulting online resources or contacting your local extension office. This information is vital for successful gardening in the Centennial State.
When to Plant Lettuce in Spring
Spring is a popular time to plant lettuce in Colorado, as the cool temperatures are ideal for its growth. Ideally, you should sow lettuce seeds directly into the garden 2-4 weeks before the last expected spring frost. This typically falls between April and May, depending on your specific location and elevation.

When to Plant Lettuce in Summer
While lettuce prefers cooler temperatures, you can still enjoy a summer harvest with proper planning. Choose heat-tolerant lettuce varieties, such as romaine or butterhead, and provide afternoon shade to prevent bolting. Successive planting, where you sow seeds every few weeks, can also extend your harvest throughout the summer months.
When to Plant Lettuce in Fall
Fall is another excellent time for growing lettuce in Colorado. The cooler temperatures and shorter days create favorable conditions for a healthy harvest. Sow seeds 6-8 weeks before the first expected fall frost, which usually occurs between September and October. Consider using cold frames or row covers to extend the growing season and protect your lettuce from early frosts.
Extending the Lettuce Growing Season
Several techniques can help you extend your lettuce growing season in Colorado. Using cold frames or row covers can provide protection from frost and extend the harvest into the colder months. Raised garden beds can also help warm the soil earlier in spring, allowing for earlier planting. Additionally, consider planting lettuce in containers, which can be easily moved to protect them from extreme weather conditions.
