How to grow Tomatillo

Physalis ixocarpa

Tomatillos are almost completely self-incompatible and require at least two plants to normally produce fruit.

As plant is a member of the Solanaceae (nightshade) family, all other parts of the tomatillo besides the fruit are inedible.

There are a large variety of tomatillo species, but many are poisonous.

While full sun is best for this plant, light shade is also well tolerated.

Growing Tomatillo from seed

Germination inside is the easiest and will ensure that your seedlings aren’t frost damaged.

An optimum soil temp for germination is 27°C, however they will germinate at lower temperatures, albeit more slowly – the soil should be at least 20°C.

Sow at a depth of approx. 0.58 inches (1.5 cm) and aim for a distance of at least 2.47 feet (76.0 cm) between Tomatillo plants. Soil temperature should be kept higher than 20°C / 68°F to ensure good germination.

Transplanting Tomatillo

Hardening off is extremely important before transplanting outside. A span of a two-week harden should suffice.

Like tomatoes, you can bury tomatillos quite deeply, leaving only about 4" of the whole plant above soil.

As Tomatillo is tender, ensure temperatures are mild enough to plant out (around 20°C / 68°F as a guideline) - wait until after your last frost date to be on the safe side.

Seed Saving Tomatillo
