When to Plant Quince in Delta County, TX

Delta County, Texas is in USDA Zone 7b. The average last spring frost is March 15 and the first fall frost is November 15, giving you a growing season of approximately 245 days.

Quince 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.
