Growing Tomato in Dallas

Dallas Zone 8a gardens enjoy a long season of around 245 days. Spring arrives fast and hot, which is great for warm-season crops but can cut the cool-season window short. Fall is often the better season for lettuce, broccoli, and greens — plant them in September after the worst summer heat breaks.

In Dallas (last frost around March 15), aim to direct sow or transplant tomato outside around March — approximately 2 weeks after your last expected frost. Starting seeds indoors 6 weeks before the last frost date gives you a significant head start.

Tomato thrives between 60°F and 85°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 60–85 days from transplant to first harvest. Very frost-sensitive. Needs warm nights.
