When to Plant in Kansas City, KS

Kansas City experiences a median last spring frost on April 9 and a median first fall frost on October 27, offering approximately 201 frost-free days for gardening enthusiasts. This window of opportunity is significant for selecting appropriate crops and planning your seasonal gardening calendar effectively.

The humid continental Great Plains microclimate of Kansas City supports a diverse array of crops, particularly those that thrive in warm, humid summers. Crops like tomatoes, peppers, and corn excel due to the extended growing season and plenty of sunshine. Conversely, crops such as lettuce and spinach often struggle with the heat, as they tend to bolt quickly under high temperatures, resulting in bitter and tough flavors.

What to plant now in Kansas City

Spring: Start planting warm-season crops such as tomatoes, peppers, and cucumbers after April 9 to ensure they are safe from the last frost. Aim for seedlings to be ready by mid-April.
Summer: This is the peak season for planting heat-loving crops like beans and squash. Make sure to sow directly into the soil after the last frost date has passed, generally by mid-May.
Fall: As the summer crops start to wane, begin planting rapid-growing fall crops, such as radishes and kale, by early September. This will ensure a good harvest before the frost on October 27.
Winter: While winter gardening is limited, consider planting cover crops in late fall to improve soil health. Consider cold-hardy plants like garlic, which can be planted in late October, shortly after the first fall frost.
