Growing Tomatillo in Columbus
Columbus sits in Zone 6a with a frost-free window of about 185 days. Cold winters keep gardeners waiting until late April for warm-season crops, but the summers are warm and productive. Starting tomatoes and peppers indoors 6–8 weeks before the last frost date is essential to get a full harvest before fall.
In Columbus (last frost around April 18), aim to direct sow or transplant tomatillo outside around May — 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.
