When to Plant Escarole in Roberts County, TX

Escarole is a broad-leaved endive with slightly bitter, sturdy leaves. The outer leaves are more bitter while the blanched heart is tender and mild.

Roberts County, Texas is in USDA Zone 7a. The average last spring frost is April 17 and the first fall frost is October 24, giving you a growing season of approximately 190 days.

At an elevation of 1,068 feet, Roberts County receives approximately 51 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 98ยฐF, so Escarole may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Escarole will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Escarole root diseases.

Escarole 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.

Escarole needs ~1,410 GDD — county provides 4,465 GDD Excellent fit
