When to Plant Parsnip in New Hampshire

Growing Parsnip in New Hampshire: Complete Guide

Parsnip (Pastinaca sativa) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in New Hampshire falls between February 18, 2027 (Zone 6b) and March 20, 2027 (Zone 4a), once soil temperatures are consistently warm enough for germination.

Because New Hampshire stretches across 6 USDA hardiness zones (4a, 4b, 5a, 5b, 6a, 6b), 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 100 days to maturity, Parsnip fits comfortably within New Hampshire's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Parsnip requires full sun and regular moisture. In the Northeast, cool summers and moderate humidity can slow warm-season crops, so choose a sheltered, south-facing spot to maximise heat.
