Parsnip

Parsnips need deep, loose, stone-free soil at pH 6.0-7.0 so their long roots can grow straight. Work in finished compost rather than fresh manure, use moderate fertility, and keep the seedbed consistently moist through slow germination.

Full sun to part shade

Even moisture; about 1 in/week including rain

4 in

First harvest

100–120 days

Tips

• Sow fresh seed 1/2 inch deep in spring and thin seedlings to 3-4 inches apart without transplanting.
• Keep the surface moist until emergence, then water deeply to encourage long roots.
• Avoid fresh manure and heavy nitrogen applications, which can encourage forked roots and excessive tops.
• Weed carefully while seedlings are small and wear gloves when handling foliage because sap can cause sun-triggered skin burns.
• Lift roots once they reach usable size; cool fall weather usually improves sweetness.
