How to Protect Your Landscape Plants from Cold Weather

Even in Florida, cold weather can damage landscape plants—especially tropical and container-grown ones. A little preparation before a cold night can help protect your plants and save you time and money in the spring.

Why Cold Damages Plants

Many tropical plants can be damaged when temperatures drop below 50°F, and freezing temperatures can kill leaves, flowers, and even entire plants. Sudden cold snaps are often harmful.

Before a Freeze

  • Plant smart: Avoid low areas where cold air settles.

  • Water the day before: Moist soil holds heat better than dry soil.

  • Skip late pruning: New growth is easily damaged by cold.

  • Use mulch: It helps protect roots and keep soil warm.

  • Cover tender plants: Use sheets, blankets, or frost cloth—make sure covers reach the ground and don’t touch leaves.

Protecting Plants During Cold Nights

  • Move potted plants indoors or closer together in a protected area.

  • A small light bulb placed under a cover can provide extra warmth.

  • Avoid plastic touching leaves—it can cause more damage.

After the Freeze

  • Don’t rush to prune—wait until new growth shows what’s alive.

  • Water plants if the soil is dry and sunny conditions return.

  • Brown leaves don’t always mean the plant is dead—give it time.

Final Tip

Florida landscapes look their best when they include a mix of cold-hardy and tender plants. With simple planning and protection, you can enjoy tropical beauty without losing everything during a cold snap.
