When to Plant Valerian in Yoakum County, TX

Valerian is a tall perennial herb with fragrant white or pink flower clusters, valued for its root which is used as a natural sleep aid. It attracts pollinators and earthworms.

Yoakum County, Texas is in USDA Zone 7a. The average last spring frost is April 6 and the first fall frost is November 5, giving you a growing season of approximately 213 days.

At an elevation of 4,523 feet, Yoakum County receives approximately 53.3 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 95ยฐF, so Valerian may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Valerian will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Valerian root diseases.

Valerian Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" โ€” every day above 50ยฐF deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Valerian needs ~3,188 GDD — county provides 4,526 GDD Excellent fit
