When to Plant Tomatillo in Minnesota

Growing Tomatillo in Minnesota: Complete Guide

Tomatillo (Physalis philadelphica) is a warm-season crop that needs a head start indoors before Minnesota's last frost. Most Minnesota gardeners begin seeds indoors around Sunday, March 29, 2026 and move transplants outside around Sunday, May 24, 2026, after the risk of frost has passed.

Because Minnesota stretches across 5 USDA hardiness zones (3a, 3b, 4a, 4b, 5a), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 75 days to maturity, Tomatillo needs the indoor head start that Minnesota's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Tomatillo requires full sun (6-8 hours) and regular (1-2 inches/week) moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
