Tomatillos are warm-season annuals from the same family as tomatoes and peppers, native to Mexico and Central America. They are self-incompatible — a single plant will produce flowers but very few fruit. Plant at least two (ideally three or more) for reliable pollination. Once established they are notably more drought-tolerant than tomatoes and prefer full sun with consistent but not excessive water. Plants sprawl and benefit from staking or caging similar to indeterminate tomatoes.
Harvest signs
Harvest when the husks fill out completely and begin to split open, exposing the fruit inside. Fruit should feel firm; size varies by variety from cherry-tomato to golf-ball size. Don't wait for the fruit to fall from the plant — pick it when the husk is papery and tight against the fruit for the best flavor and storage life.
▶Planting reference— Depth, spacing, pH, light
Depth
Start seeds one-fourth inch deep indoors 6 to 8 weeks before the last frost; transplant outdoors 1 to 2 weeks after the last spring frost when soil is warm
Aphids:leaf curling, discoloration, and sticky leaves↗
Tomato hornworm:large green caterpillars that defoliate plants and feed on fruit↗
Common diseases · 3
Early blight:causes dark spots with concentric rings on lower leaves; spreads upward as the plant ages↗
Bacterial spot:small, dark spots on leaves and fruit; spots may have yellow halos↗
Tobacco mosaic virus:mottled or distorted leaves; stunted growth; reduced fruit set↗

Tip: Plant at least two — tomatillos are self-sterile and won't set fruit alone. Harvest when husks fill out and start to split.
Common questions
How much water does tomatillo need?
Tomatillo is fairly drought-tolerant once established and can dry out further between waterings. A soil-moisture range of about 30–50% is plenty — overwatering does more harm than a little dryness.
Can I grow tomatillo in a raised bed or container?
Yes — tomatillo does well in raised beds and is happy in a decent-sized container too, as long as drainage is good.
Does tomatillo come back every year?
No — tomatillo is an annual. It completes its life in one season, so you replant it each year.
