Growing Tomatillos: A Complete Profile
By Growing Home Greens Team · July 24, 2026
Tomatillo is a tomato relative grown for its tart, green (or purple) fruit, each wrapped in a papery husk. It’s a staple of salsa verde and green chili, and it grows a lot like a sprawling, vigorous tomato plant.
Starting and spacing it
Start seed indoors 4-5 weeks before your planned transplant date, and set plants out about 1-2 weeks later than you’d plant your earliest tomatoes, after frost danger has fully passed. Space plants 24-36 inches apart. They get large and benefit from staking or a cage, much like a determinate tomato.
The one-plant problem
Tomatillo’s most common problem isn’t a growing mistake at all: the plant isn’t self-fertile, so a lone tomatillo plant will flower heavily and set little or no fruit. Always plant at least two, and two different varieties cross-pollinate at least as well as two of the same one, so there’s no downside to mixing a green type like Toma Verde with a purple type.
The same bed as tomatoes and peppers
Tomatillo shares soil, sun, and pest needs with tomatoes and peppers, so it slots naturally into the same bed. Fruit is ready to pick once it fills out and splits its husk, or once the husk turns papery and tan.

How many Tomatillo plants fit per square foot?
Spacing: about 4 square feet per plant (square-foot-gardening spacing). Mature height: 2-4 ft.
Varieties worth considering
- Toma Verde: An early, sweet-flavored green tomatillo that SDSU Extension lists among the reliable home-garden picks. Since a single tomatillo won't set fruit alone, pair it with a second variety, such as a purple type, rather than two plants of the same one. You get cross-pollination and two different flavors in the same salsa batch. (source)
- De Milpa: The purple cousin Toma Verde is meant to be paired with, per Johnny's: smaller round fruits with excellent storage life, husks that dry naturally within two weeks. The cross-pollination partner this profile's own advice calls for, not just an alternative. (source)
