About Parsnip
Parsnips are an underrated root vegetable — sweet and nutty after frost exposure. They need deep, loose soil and a long season but reward patience with exceptional flavor.
Direct sow only — parsnips do not transplant well. Sow fresh seed (old seed has poor germination) 3-4 weeks before last frost. Thin to 6 inches. Leave in ground after frost — cold converts starch to sugar.
Gardening in Washington
Washington has dramatically different climates. The wet maritime west (Zone 8a-8b) is mild and productive year-round. Eastern Washington is semi-arid and colder (Zone 5-6) with hot dry summers.
