Crookneck Squash Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

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.
