Quince is a small ornamental tree producing fragrant, golden fruits that are too hard and astringent to eat raw but transform into a beautiful rose-colored paste when cooked.

Sterling County, Texas is in USDA Zone 8a. The average last spring frost is March 24 and the first fall frost is November 12, giving you a growing season of approximately 233 days.

At an elevation of 2,929 feet, Sterling County receives approximately 50.9 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 99°F, so Quince may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Quince will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Quince root diseases.

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" — 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.

Quince needs ~35,405 GDD — county provides 5,650 GDD May not mature
