When to Plant Borage in Upshur County, TX

Borage is a self-seeding annual herb with star-shaped blue flowers that attract pollinators. Its leaves have a cucumber-like flavor and the flowers are edible.

Upshur County, Texas is in USDA Zone 8a. The average last spring frost is March 9 and the first fall frost is November 17, giving you a growing season of approximately 253 days.

At an elevation of 51 feet, Upshur County receives approximately 74 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 95ยฐF, so Borage may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Borage will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Borage root diseases.

Borage 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.

Borage needs ~1,169 GDD — county provides 5,376 GDD Excellent fit
