When to Plant Tomatillo in Tennessee

Growing Tomatillo in Tennessee: Complete Guide

Tomatillo (Physalis philadelphica) is a warm-season crop that needs a head start indoors before Tennessee's last frost. Depending on your zone, Tennessee gardeners start seeds indoors between February 6, 2027 (Zone 8a) and March 4, 2027 (Zone 6b), then move transplants outside once their zone's last frost has passed — the zone table above has your exact dates.

Because Tennessee stretches across 4 USDA hardiness zones (6b, 7a, 7b, 8a), planting windows can shift by as much as two to four 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 Tennessee'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. Southeastern summers are hot and humid; mulch heavily to retain moisture and shade roots during peak heat.
