Growing Squash (Summer) in Florida
State-Specific Growing Tips
North Florida: direct sow from late February through April for spring harvest, and again in August-September for fall. Central Florida: plant from January through March, and September through October. South Florida: October through February is prime squash season. Florida's sandy soils need heavy amendment — mix in 3-4 inches of compost before planting. Mulch immediately to retain the moisture that sand releases so quickly. Stake or trellis vining varieties to improve air circulation, which reduces the fungal diseases that thrive in Florida's humidity.
Recommended Varieties for Florida
UF/IFAS Extension recommends Straightneck Early Prolific, Crookneck, and Zucchini Elite for Florida conditions. For winter squash, Seminole Pumpkin is the clear winner — this Florida native is adapted to the state's heat, humidity, and pest pressure in ways that no northern variety can match. It's practically a weed in terms of vigor. Calabaza (tropical pumpkin) also thrives.
Common Challenges in Florida
Downy mildew, powdery mildew, and gummy stem blight are the disease trifecta in Florida's humid conditions. Plant during the drier months when possible. Pickle worm bores into developing fruits — it's devastating in south Florida and arrives later in the season in north Florida. Whiteflies transmit viruses that cause leaf curling and stunted growth. Nematodes in sandy soils attack roots — rotate locations and use Seminole Pumpkin's natural resistance.
Growing Tips
Harvest when fruits are 6-8 inches long for best flavor. Larger squash become seedy and tough.
