How to Protect Palm Trees from Cold

While cold hardy palms can tolerate freezing temperatures, tropical palms may suffer from the cold damage.

Usually, palm tree owners, that live in the warm climates, don’t need to worry about cold weather. But with unpredictable winters in the last couple of years, freezing temperatures don’t come as a surprise.

Cold weather can effect palm trees in different ways. First, freeze can damage the palm tissue in the trunk, which may limit the ability of the palm to provide leaves with enough water. Unfortunately, palm trees can’t regenerate conducting tissue and will die after a while. Cold temperatures can also slow down the root activity and growth rate of the palm. Here is an article on How to Save Cold Damaged Palm Tree.

If your palm tree haven’t been severely damaged, you need to help it with the recovery and also prepare for the next winter. There are number of things you can do to prepare and protect your palm tree during cold temperatures:

I use Scotts Organic Classic Black Mulch How to Protect Palm Trees from Cold because it’s made from natural forest products, not waste wood and it lasts for over a year. Great product.

6. Warm Cover

During cold days cover it is a good idea to cover your palm. If your palm tree is small, you can cover it with a weighted down box or a blanket. Don’t let the tree sit under the cover for more than 3 days in a row. After 3 days, uncover your palm during the day to provide it with some sunlight. If it is a large palm tree, use a blanket, burlap or other warm material. Wrap it around the trunk and secure it with a duck tape. You should remove all the covers once the weather is warm again. Avoid using a plastic for covering, as it may traps moisture underneath that will freeze and cause more damage.

7. Heater and Light Bulbs

Another way to warm up your palm, is to place a small heater underneath the cover or put some light bulbs. Be careful, when using any source of heat under the cover. It should not touching the material nor the tree. You can also, use Christmas lights around the trunk of the palm to keep it warm.

I hope these tips will help you prepare your palm trees for cold weather. Let me know if you have any questions.
