How to Grow Tomatillo — Croft & Covey

Growing Conditions

Tomatillos need the same conditions as tomatoes — warm soil, full sun, and frost-free growing season. They are more heat-tolerant than tomatoes and less fussy about soil fertility. They grow vigorously and can reach 3–4 feet tall and wide.

Important: Plant at least two tomatillo plants for cross-pollination. A single plant produces very little fruit regardless of how healthy it looks.

Cold climates: Start indoors 6–8 weeks before last frost. Transplant after last frost when soil has warmed. Choose varieties with 70–75 days to maturity for Zone 5.

Warm climates: Long productive season. Direct sowing is possible but starting indoors gives a head start.

Sowing & Planting

Start indoors ¼ inch deep at 70°F–80°F soil temperature. Transplant at 6–8 weeks old, spacing 24–36 inches apart. Cage or stake at planting — plants sprawl significantly without support.

Care & Maintenance

Water consistently but tomatillos tolerate drought better than tomatoes. Feed at planting with compost; additional fertilizing is usually not needed in average soil. Remove suckers to maintain manageable plant size if desired, though this is optional.

Common Problems

No fruit on a single plant — always plant two or more. Aphids can be heavy on new growth — control with water or insecticidal soap. Flea beetles damage young transplants — use row cover. Tomatillos are generally less pest-prone than tomatoes.

Harvest

Harvest when fruit fills the husk completely and the husk begins to split or turn papery and tan. The fruit inside should feel firm. Green tomatillos are tart; yellow or purple ones are milder and sweeter. Remove the papery husk and wash off the sticky coating before using. Store at room temperature for 1–2 weeks or refrigerate for up to a month.

Varieties

Verde (standard green) tomatillos are the most common and the basis for traditional salsa verde. Purple tomatillos (Purple de Milpa) are sweeter and milder with attractive coloring that intensifies when cooked. Pineapple tomatillo is a very sweet yellow type eaten fresh. For most culinary uses, a standard green variety is the right choice.
