Understanding Zone 9A — Northeast Florida's Climate
Northeast Florida falls in USDA Hardiness Zone 9A, meaning average winter lows range from 20°F to 25°F. Most years, St. Augustine to Daytona Beach sees only a few nights below freezing, but every few years a hard freeze can dip into the teens. Choosing the right plants means enjoying tropical beauty without annual replacement costs.

Freeze Protection Tips for NE Florida
Even cold-sensitive tropicals like Hibiscus, Bougainvillea, and Mandevilla can survive NE Florida winters with basic protection:
- Cover with frost cloth (not plastic) when temperatures drop below 35°F
- Water deeply before a freeze — moist soil retains more heat than dry soil
- Mulch root zones with 3-4 inches of mulch or coquina shell to insulate roots
- Plant near structures — south-facing walls and covered patios provide radiant heat
- Don't prune freeze damage immediately — wait until spring to see what recovers
