Florida winters are usually mild, but when a cold snap hits, it can be tough on tropical and newly planted landscapes. Sudden temperature drops — even just a few hours below 40°F — can stress or damage sensitive plants. Here’s how to protect your yard when cold weather rolls in unexpectedly.

1. Know Your Cold-Sensitive Plants

Plants like hibiscus, crotons, philodendrons, and newly planted palms or tropicals are most at risk. If a freeze is in the forecast, these are the first ones to protect.

2. Cover Up

Use breathable fabric like old sheets, burlap, or frost cloth (never plastic directly on leaves). Drape covers loosely over the entire plant, and anchor them to the ground to trap warmth.

3. Bring Potted Plants Closer Together

Move containers to a protected area near your house or under a covered porch. Grouping pots together also helps create a warmer microclimate.

4. Mulch Matters

A fresh layer of mulch (2–3 inches) helps protect plant roots by insulating the soil. If you recently had mulch installed, you're already one step ahead.

5. Hold Off on Pruning

Pruning before or immediately after a cold snap can make plants more vulnerable. Wait until the risk of frost is over before trimming damaged growth.

Even in Florida, winter can surprise you. A little prep can keep your plants healthy and thriving until spring returns.
