Florida Zone 10a Planting Guide for April

Unlike northern states that follow a single spring-to-autumn growing calendar, Florida spans four distinct climatic bands—from temperate North Florida and the Panhandle (Zones 8a and 8b) through transitional North-Central and Central Florida (Zones 9a and 9b) down to subtropical South Florida (Zones 10a and 10b) and the tropical Florida Keys (Zone 11a). Knowing your specific sub-zone and planting month is the difference between harvesting crisp, sweet brassicas all winter and watching cool-season crops bolt in sudden warm spells.

How Florida's Three Major Gardening Seasons Work

Across most of the Sunshine State, successful organic gardeners divide the year into three distinct planting windows rather than one:

• Fall & Winter Cool Season (October – February): As summer humidity breaks and night temperatures cool into the 50s and 60s, Central and South Florida enter their most productive vegetable season. Broccoli, cauliflower, kale, collards, cabbage, carrots, radishes, beets, lettuce, spinach, peas, strawberries, and culinary herbs thrive with minimal pest pressure and gentle winter sunshine.
• Spring Warm Season (February – May): Once the threat of late freezes passes—mid-February in Zone 9b and early March in Zones 8b and 9a—warm-season crops take center stage. Heirloom tomatoes, sweet and hot peppers, bush and pole beans, cucumbers, zucchini, yellow squash, sweet corn, and watermelons grow rapidly before midsummer night temperatures climb above 75°F.
• Tropical Summer Season (June – September): When daily thunderstorms, intense UV radiation, and high night humidity arrive, heat-loving crops keep the homestead productive. Southern cowpeas, yardlong beans, okra, calabaza squash, sweet potatoes, tropical spinaches, ginger, turmeric, and pollinator-attracting zinnias and sunflowers flourish through the warmest months while raised beds are replenished with compost and organic mulch.
