Hot peppers range from mildly spicy jalapenos to scorching superhots. They require long, warm growing seasons and produce capsaicin that gives them their heat.

Parmer County, Texas is in USDA Zone 7a. The average last spring frost is April 16 and the first fall frost is October 23, giving you a growing season of approximately 190 days.

At an elevation of 1,686 feet, Parmer County receives approximately 53.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 95°F, so Hot Peppers may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Hot Peppers will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Hot Peppers root diseases.

Hot Peppers 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.

Hot Peppers needs ~2,019 GDD — county provides 4,037 GDD Excellent fit
