Tomatillo: complete guide

Overview

The Tomatillo (Physalis ixocarpa), also called Coqueret or Mexican husk-tomato, belongs to the Solanaceae family. This annual vegetable plant originates from Mexico. The plant is recognized for its unique fruits, enclosed within a papery husk (calyx), that remain green when harvestable. Tomatillos are popular in Mexican cuisine and easy to grow in temperate climates.

Appearance and bloom

The Tomatillo grows as a sprawling shrub 1 to 1.5 meters tall and wide. The leaves are large, green, and slightly rough to the touch. The flowers are small, yellow or greenish-white, hidden among the foliage. Fruits appear after flowering and develop within papery husks. When ripe, fruits measure approximately 2-3 centimeters diameter, light green and firm. The papery husk splits when the fruit is mature.

Ideal location

The Tomatillo thrives best in warm, sunny locations with well-draining soil. The plant requires warm weather and grows best when average temperatures remain above 15 degrees Celsius. Protection from strong wind is important as branches become heavy with fruit.

Soil

This plant grows best in rich, organic matter-containing soil. Add compost or rotted manure when planting. The plant accepts various pH levels but grows better in neutral to slightly acidic soil. Good drainage is essential to prevent root rot.

Watering

The Tomatillo requires regular water, especially during growth and fruiting. Water at ground level deeply but not daily. Excess water can cause root rot. Drip irrigation systems are ideal. In dry periods, water daily.

Pruning

Pruning promotes better fruiting. Remove the growing tip of young plants when 30 centimeters tall to encourage branching. Remove dead or damaged leaves regularly. You can remove lower leaves to improve air circulation.

Maintenance calendar

April-May: Seed sowing indoors. May-June: Transplanting and staking. June-July: Flowers and first fruits. July-August: Harvesting green tomatillos. August-September: Final harvest before frost.

Winter hardiness

The Tomatillo is not winter-hardy. It dies as soon as frost appears. In temperate climates it must be replanted annually. In warm regions it can grow perennially if protected from frost.

Companion plants

The Tomatillo grows well with other summer vegetables such as tomato, pepper, and eggplant. Avoid planting together with other Solanaceae relatives that share similar pest diseases. Basil and other herbs help. Flowering shrubs attract pollinators.
