About Tomatillo

Tomatillos are the tangy green tomato-like fruit essential to Mexican salsa verde and Indian-inspired green chutneys. They grow in a papery husk and are extremely productive once established. Always plant at least two for pollination.

Must grow at least two plants for fruit set — single plants rarely produce. Start indoors 6-8 weeks before last frost. Support with stakes or cages. Harvest when husks split and fruit fills the husk. Prolific producer — expect more than you need.
