Planting Tomatillos

Tomatillos are very sensitive to cold temperatures, and seeds should be started undercover 6-7 weeks before your last frost date. Tomatillos are not self-pollinating, so you will need to grow at least two plants for any fruit to develop. Plant seeds 0.5cm (1/4") deep, and optionally use a heating mat to help seedlings emerge. Tomatillos prefer well-draining soil and thrive in full sun.

Growing Tomatillos

Once the last frost has passed, harden off seedlings by putting them in a safe place outside for two hours, increasing by one hour every day for a week. Once acclimated to the outside conditions, plant each tomatillo seedling 75cm (30") apart and water in well. Tomatillos have strong root systems and can withstand drought and heat, but consistent watering will result in higher quality fruits. When watering, avoid getting the leaves wet or splashing soil onto the leaves, as this can encourage diseases which would damage the plant.

Tomatillos will need supports such as a trellis as they grow, or can be left to bush and sprawl out, in which case extra space between plants will be needed. If you notice low or no fruit developing in the husks, you can assist with hand pollination. Using a clean cotton swab or brush, gently collect pollen from the flowers on one plant and dab it into the flowers of another plant.

Harvesting Tomatillos

Tomatillos are ready to harvest once they are firm and fill the husk, which should be drying and beginning to split. Gently snip the fruit off the plant, and store it with the husks intact in a plastic bag in the fridge for up to 3 weeks. Tomatillos are covered in a sticky residue that will need to be washed off before using.
