Growing Dill in Massachusetts: Complete Guide

Dill (Anethum graveolens) is a crop that grows best when sown directly in the garden. In Massachusetts, the right time to direct sow is around Friday, March 13, 2026, once soil temperatures are consistently warm enough for germination.

Because Massachusetts stretches across 3 USDA hardiness zones (6a, 6b, 7a), 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 40 days to maturity, Dill fits comfortably within Massachusetts's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Dill requires full sun (6-8 hours) and moderate moisture. Most of Massachusetts receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
