🍈 Can I Plant Cantaloupe in Houston, TX?
Temperature conditions are suitable for Cantaloupe.
Growing Cantaloupe in Houston
Houston's Zone 9a climate offers an extraordinarily long growing season — over 300 days. Summers are hot and humid, which suits tropical crops but can stress cool-season greens. Many Houston gardeners grow two full seasons: spring (Feb–June) and fall (Sept–Dec), skipping the most brutal summer heat for sensitive crops.
In Houston (last frost around February 10), aim to direct sow or transplant cantaloupe outside around February — approximately 2 weeks after your last expected frost. Starting seeds indoors 4 weeks before the last frost date gives you a significant head start.
Cantaloupe thrives between 70°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 70–90 days from transplant to first harvest. Needs long warm season.
