Potatoes 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.

Potatoes needs ~2,375 GDD — county provides 5,350 GDD Excellent fit

Sandy soil in Gaines County dries quickly — mulch Potatoes with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.
