Polk County, Florida gardeners: here's your July plan
July is a pivotal month for Polk County, Florida gardens. Focus on these tasks first and you'll set up the rest of the season for success.

-
Keep heat-survivor crops productive

Grapes 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.
