Growing Corn in Kansas City

Kansas City straddles the Missouri–Kansas border in Zone 6a, with about 185 frost-free days. Spring weather can be unpredictable, but once warm-season crops go in after mid-April, the summer growing season is productive and warm. Fall arrives moderately, giving time for cool-season crops planted in August. The region's rich prairie soils are naturally fertile and well-suited for vegetables.

In Kansas City (last frost around April 15), aim to direct sow or transplant corn outside around April — approximately 2 weeks after your last expected frost.

Corn thrives between 65°F and 95°F. It is frost-sensitive, meaning a single freeze at 32°F will damage or kill it — always wait until frost danger has fully passed. Expect 60–100 days from transplant to first harvest. Needs warm soil. Plant in blocks.
