How to Plant, Grow, and Harvest Tomatillo

The tomatillo is a warm-weather crop. Tomatillos are easy to grow and bear fruit all summer long.

Tomatillo fruit is used to make sauces and salads and is very popular in Mexican and Southwestern cuisine. The tomatillo has a sweet-sharp flavor recognizable in the green sauce used on chicken enchiladas and fresh green salsa for tortilla chips and tacos. The tomatillo is less juicy and more richly flavored than the tomato.

The tomatillo is a bushy, sprawling plant that grows to 4 feet (122 cm) tall and wide. The fruit is round and green and is surrounded by a papery husk.

Where to Plant Tomatillos

Grow a sunny location.
The soil should be humus-rich, water-retentive, and well-drained.
Add aged compost or commercial organic planting mix to the soil before sowing or transplanting tomatillos.
One tomatillo plant will yield about 1 pound (.45 kg) of fruit over the season. Most recipes call for ½ pound of fruit to make a sauce. Plant at least 2 to 3 plants.

Tomatillo Planting Time

Sow tomatillo seeds indoors 4 to 5 weeks before transplanting seedlings into the garden.
Sow directly in the garden 4 to 6 weeks after the last frost after the soil has warmed—usually 1 to 2 weeks after tomatoes.
Seeds will germinate in 5 days if sown in moist, warm soil.

Planting and Spacing Tomatillos

Set transplants in the garden just like you would tomatoes—up to ⅔ of the seedlings can be buried much like a tomato.
You will need two or more tomatillo plants for blooms to be pollinated and fruit to be produced.
Thin tomatillo seedlings to at least 10 inches (25 cm) apart but more commonly 2 to 3 feet apart (61-91 cm) apart.
Bees and other pollinators will be attracted to the plant’s yellow blossoms.

Tomatillo Companion Plants

Grow tomatillos with tomatoes, peppers, and eggplants.

Container Growing Tomatillos

Grow tomatillos in a container as you would a tomato; you will need at least a 5 gallon (19 liter) container.

Tomatillo fruit and flower — Tomatillos can be trained but are usually allowed to grow bush-like and sprawl.

Watering and Feeding Tomatillos

Keep the soil just moist as plants develop.
Cut back on the water once fruiting begins, but don’t let the soil totally dry out.
Compost-rich soil should be sufficient, but plants can be fed with an organic fertilizer rich in phosphorus and potassium, 5-10-10.

Tomatillo Care

Train tomatillos to a trellis, stake, or cage, but more commonly the plants are allowed to sprawl.
Keeping plants off the ground by covering beds with black plastic will discourage fungus problems common in regions of high humidity.

Tomatillo Pests and Diseases

Flea beetles may chew holes in the leaves, but will likely not damage the plants or affect yield.
Birds will be attracted to the fruit near harvest.
Tomatillos are susceptible to fungal diseases; allow for plenty of air circulation to prevent disease.

Tomatillo harvested — Tomatillos are ripe when their papery skin falls away easily.

Harvesting Tomatillos

Tomatillos mature in 65 to 70 days. Harvest the fruit when walnut-size—about 2 inches (5 cm) wide– or smaller if fully developed and deep green.
When fruits begin to turn yellow or purple, they are past their prime and will lack the fresh, tart flavor of green tomatillos.
Don’t remove the papery husk until you are ready to use the fruit.

Storing and Preserving Tomatillos

Use tomatillos fresh in sauces and salads.
Fruits will store for 2 to 4 weeks at 45°F (7°C) in the vegetable bin of the refrigerator.
Tomatillos can be frozen by peeling the husk, rinsing, drying the fruit, and placing them in a freezer bag; double bag to prevent freezer burn.
