Cold protection for tropical plants

Pushing the limits of tropical gardening

The year is almost over but the winter is not. This Christmas weekend at our Sebring B-farm we had it down to 30F. As a tropical gardener, winter can be challenging, especially if you grow plants outside of tropical zones.

To protect your garden from the cold, consider the following:

1. Monitor freeze watches and be prepared to take action if necessary.
2. Create temporary structures like mini-greenhouses using PVC pipes, carport frames, or bamboo sticks to support covers.
3. Use covers such as frost cloth, cardboard boxes, blankets, and bed sheets.
4. Use Christmas lights and other heating elements, including propane heaters, to keep plants warm.
5. Add a layer of heavy mulch around plant trunks to protect them from the cold.
6. Apply plant boosters that improve cold hardiness, such as Sunshine Epi, Sunshine-Si, and Sunshine Superfood.

At TopTropicals B-Farm, we sprayed our plants with a special cold hardiness treatment Sunshine-Si and covered and wrapped everything we could. We also moved cold sensitive species inside greenhouses. All of our plants are looking great and happy!

🌴 How cold hardy are palm trees and how to protect them in winter
  • 🌴 Most palms are tropical plants and require a frost-free climate to grow outdoors. However, there are a few exceptions. Adjust care depending on your zone and palm species. 
  • 🌴 Some cold-hardy species can handle harsher conditions, with proper protection, making them great options for gardeners in zones that experience occasional freezes.
  • 🌴 Mulch generously: Apply a thick layer of mulch around the base to insulate roots. Keep mulch a few inches away from the trunk to prevent rot.
  • 🌴 Water before frost: Water deeply before a freeze to stabilize soil temperature and prevent dehydration.
  • 🌴 Cover young palms: Wrap smaller or sensitive species in burlap, frost cloth, or blankets. Avoid plastic, as it can trap moisture and cause damage.
  • 🌴 Protect the crown: For cold-sensitive palms, bundle fronds upwards and wrap the crown with cloth or burlap to shield the growing point.
  • 🌴 Use heat sources: Place Christmas lights (non-LED) or a heat lamp near the tree, ensuring they’re safe and don't touch the foliage.
  • 🌴 Avoid pruning: Keep fronds intact during winter—they provide natural insulation.
  • 🌴 Species-specific care: Cold-hardy palms need less protection. Delicate types require more attention, including covering and relocating potted ones indoors.

Hardy Plumeria Pudica

Q: I have ordered plumeria pudica from you in March and it is thriving really well here in Rancho Cordova, California. The current temperatures are ranging from 68 to 32 degrees Fahrenheit. My USDA zone is 9b. Does this plumeria pudica survive outside with temperatures dropping in coming winter in CA?

A: From our experience, Plumeria pudica is pretty cold hardy and takes some cold spells in spite of being a tropical species.
Our trees (well-established) took a few hours of freeze with no significant damage.
Potted plants are less hardy than in-ground plants. However, their advantage is, they are easy to move indoors or inside warmer place like garage, etc. If the temperature stays borderline around 32F for a few hours, the plant should be safe as long as warm day temperatures follow a cold night. For longer periods of cold, move the plant inside.
Make sure do not overwater and keep Plumeria on a dry side during winter, since cold and wet is a bad combination and may cause root problems.
Above is the picture of Plumeria pudica tree growing in Cape Coral, FL where low temperatures in winter sometimes go down to upper 20's for a few hours.

To improve cold hardiness of Plumerias and other tropical plants, use SUNSHINE-Epi-T for plant thermal protection and immune system boost.
Make sure to fertilize plants on regular basis to keep them strong and vigorous. The stronger and bigger the plant, the hardier it is!

Pink N Good Daily Plant Food - Flower Booster
