Peppers 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.

Peppers needs ~1,538 GDD — county provides 5,453 GDD Excellent fit

Growing Tips for Peppers in Houston County

Direct sow Peppers outdoors after March 02 in Houston County when soil has warmed and frost danger has passed.

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