Summer highs average 96°F, so Calabash may need afternoon shade and extra watering during peak heat.

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

Calabash 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.

Calabash needs ~2,200 GDD — county provides 5,368 GDD Excellent fit
