Rains County, Texas is in USDA Zone 8b. The average last spring frost is March 13 and the first fall frost is November 16, giving you a growing season of approximately 248 days.

At an elevation of 363 feet, Rains County receives approximately 66.1 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 95°F, so Stevia may need afternoon shade and extra watering during peak heat.

Ample rainfall means less supplemental watering, but ensure good drainage to prevent Stevia root diseases.

Stevia 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" — every day above 50°F 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.

Stevia needs ~1,594 GDD — county provides 5,270 GDD Excellent fit
