Growing Tomatillos in Zone 10A

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.

Zone 10A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

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
