Hot 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.

Hot Peppers needs ~1,805 GDD — county provides 4,788 GDD Excellent fit

Direct sow Hot Peppers outdoors after March 09 in Henderson County when soil has warmed and frost danger has passed.

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