Tomatillos are the backbone of Mexican green salsa. They thrive in heat and are surprisingly easy to grow — but you must plant at least two for cross-pollination.

Top Growing Tips

  • Always plant two or more for successful fruit set
  • The papery husk splits when fruit is ripe — don’t harvest early
  • Highly productive once established; expect 3-5 lbs per plant
  • Stake plants as they can sprawl 3-4 feet wide
  • Save seeds easily — they’re reliably open-pollinated

Companion Planting

Good companions: basil, peppers, marigolds, cilantro

Avoid planting near: fennel, brassicas

Harvest Timeline

60-80 days from transplant; harvest when husk is tight and fruit is firm
