The Short Answer

Tomatillos are frost-sensitive and need warm soil and air temperatures to thrive. Start seeds indoors 6 weeks before your last frost date, then transplant outside 2 weeks after your last frost when soil temperatures reach at least 60°F. Enter your zip code on our homepage tool for exact dates.

How to Grow Tomatillos

Tomatillos are the essential ingredient in salsa verde, and they're easier to grow than tomatoes — more resistant to disease, less attractive to pests, and more productive per plant. The critical rule: plant at least two plants for cross-pollination. A single tomatillo plant produces foliage but no fruit. Harvest when the papery husk splits and the fruit fills it completely. The sticky residue on the fruit is normal — rinse it off before cooking. Tomatillos are prolific self-seeders in mild climates; volunteer plants pop up everywhere the following spring.

Starting Seeds Indoors

Begin tomatillos seeds indoors 6 weeks before your average last frost date. Seeds need soil temperatures of at least 60°F to germinate, which typically takes 7-14 days. Provide 12 hours of light per day using a south-facing window or grow lights.

Transplanting

Move seedlings outside 2 weeks after your last frost date, once soil temperatures reach 60°F. Harden off seedlings for 7 days before transplanting by gradually exposing them to outdoor conditions.

Growing Tips

Plant at least two for cross-pollination — a single tomatillo won't set fruit. Ripe when the husk splits and fruit fills it completely. Prolific — 2-3 plants produce enough for dozens of jars of salsa verde.
