When to Plant Parsnip in Edwards County, TX

Parsnips are a sweet, nutty root vegetable that develops best flavor after exposure to frost. They require a long growing season but reward patient gardeners.

Edwards County, Texas is in USDA Zone 8b. The average last spring frost is April 2 and the first fall frost is November 8, giving you a growing season of approximately 220 days.

Summer highs average 102°F, so Parsnip may need afternoon shade and extra watering during peak heat.
