Malabar spinach is a tropical vine with thick, succulent leaves that taste similar to spinach. Unlike true spinach, it thrives in heat and humidity.

Walton County, Florida is in USDA Zone 9a. The average last spring frost is March 14 and the first fall frost is November 15, giving you a growing season of approximately 246 days.

At an elevation of 200 feet, Walton County receives approximately 52.8 inches of rainfall annually with predominantly sand soil. Summer highs average 95°F, so Malabar Spinach may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Malabar Spinach will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Malabar Spinach root diseases.

Malabar Spinach 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.

Malabar Spinach needs ~1,328 GDD — county provides 5,227 GDD Excellent fit
