When to Plant in Colorado Springs, CO

In Colorado Springs, gardeners face a median last spring frost date of May 22 and a median first fall frost date of September 24, which gives the area approximately 125 frost-free days. This limited window necessitates careful planning, particularly for frost-sensitive crops. With these dates in mind, understanding local growing conditions will prove critical in maximizing yield and ensuring success in your garden.

The continental mountain microclimate in Colorado Springs is characterized by cold nights and intense sunlight. These conditions are ideal for growing hardy crops like potatoes and carrots, which benefit from the cooler nighttime temperatures, helping to maintain moisture and prevent bolting. However, crops such as lettuce and basil may struggle, as the extreme temperature fluctuations can lead to poor growth and flavor. Understanding these dynamics will help enhance your gardening efforts in this unique environment.

What to plant now in Colorado Springs

In early spring, consider planting cool-season crops such as peas and spinach, ideally between May 22 and May 22, to take advantage of the frost-free period that begins after May 22.
As spring transitions to summer, start sowing warm-season crops like tomatoes and peppers. Aim for planting from May 22 to May 22, allowing these heat-loving plants to thrive through the frost-free days.
In late summer, plant fall crops, such as kale and Swiss chard, between September 24 and September 24. This will ensure they have enough time to mature before the first frost on September 24.
As autumn begins, focus on winter preparations. Planting cover crops or garlic in early October can enhance soil health and provide a head start for next year’s growing season before the frost settles in.
