When to Plant Parsnip in Arizona

Growing Parsnip in Arizona: 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 Arizona falls between November 30, 2026 (Zone 10a) and February 28, 2027 (Zone 5b), once soil temperatures are consistently warm enough for germination.

Because Arizona stretches across 10 USDA hardiness zones (5b, 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b, 10a), 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 Arizona'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 arid Southwest, intense sun and low humidity mean irrigation is essential; mulch to prevent rapid soil moisture loss.
