Summer highs average 95ยฐF, so Peppers may need afternoon shade and extra watering during peak heat.

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" โ€” every day above 50ยฐF 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.

Growing Tips for Peppers in Jefferson County

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