What to do in June
Your Jefferson Parish, Louisiana garden is entering a new phase. Here's what's on the schedule for June and why each task matters now.
Cantaloupe is a sweet, aromatic melon with salmon-colored flesh and a netted rind. It requires a long, warm growing season and is the quintessential summer fruit.
Jefferson Parish, Louisiana is in USDA Zone 9b. The average last spring frost is January 27 and the first fall frost is December 18, giving you a growing season of approximately 325 days.
At an elevation of 314 feet, Jefferson Parish receives approximately 55.2 inches of rainfall annually with predominantly sandy loam soil.

Cantaloupe 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.
