Growing Tomatillo in Arlington

Arlington, between Dallas and Fort Worth in Zone 8a, enjoys a long growing season of about 245 days. The clay-heavy North Texas soil benefits from annual organic matter additions, but once amended it supports excellent vegetable production. Fall gardening from September is outstanding, and the spring window from March through June before summer heat peaks is highly productive for warm-season crops.

In Arlington (last frost around March 15), aim to direct sow or transplant tomatillo 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.

Tomatillo thrives between 65°F and 90°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 75–100 days from transplant to first harvest. Plant at least 2 for cross-pollination. Papery husks split when ready to harvest. Very vigorous grower.
