Growing Mint in Pennsylvania: Complete Guide

Mint (Mentha spicata) is a crop that grows best when sown directly in the garden. In Pennsylvania, the right time to direct sow is around Sunday, March 8, 2026, once soil temperatures are consistently warm enough for germination.

Because Pennsylvania stretches across 7 USDA hardiness zones (5a, 5b, 6a, 6b, 7a, 7b, 8a), 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 90 days to maturity, Mint fits comfortably within Pennsylvania's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Mint requires partial shade to full sun and regular (keep moist) moisture. Most of Pennsylvania receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
