Palm tree leaves hanging down due to heavy snow If you have palm trees or are planning to purchase a palm tree, you may have asked yourself, can palm trees survive the snow? Palm trees are hardy plants, but many people ask us if they are cold-hardy.  In this article, we will discuss whether or not palm trees can survive the snow and what is the lowest temperature a palm tree can survive.

You might be surprised to learn that palm trees can survive the snow. Depending on the type of palm tree, it can exist in snow-covered conditions for a short time or can be winterized.

While cold-hardy palm trees exist, cold climates can only be endured for a limited amount of time. Read below to learn how to ensure your palm can adequately withstand those cold and snowy winter months.

What is the Most Cold-Hardy Palm Tree?

There are many cold-hardy palm trees available. Some species of palm trees even originate from cold climates such as Southern Asia. The Trachycarpus species of trees, which are fan palms, are often regarded as the most cold-hardy palm tree.

Out of this species, the most common is the Trachycarpus fortunei, also known as Windmill or Chusan Palm, and the Trachycarpus takil, also known as the Kumaon palm. The Windmill palm can grow up to 12-20 meters high. It is native to Southern Asia and grown successfully across the globe. The Kumaon palm can grow up to 10-15 meters tall and is indigenous to the Himalaya.

What is the Lowest Temperature a Palm Tree Can Survive?

The Windmill Palm can tolerate the lowest temperature at 5 degrees Fahrenheit (-15 degrees Celsius). The Kumaon palm can handle temperatures as low as -4 degrees Fahrenheit; however, exposure to extreme cold will likely result in foliage damage. Palm cannot withstand temperatures that are too low as the plants are primarily composed of water. When their trunks freeze, their cells, and possibly the entire plant, can die.

Can Palm Trees Survive the Winter Outside?

Depending on how low the temperature drops, palm trees can survive the winter outside. If you have palm trees planted outside on your property and are unable to move them inside for the winter, there are a few things you can do to ensure your palm tree survives the winter outside.

Plant Cold-Hardy Palms

Not all palm trees are cold-hardy, some are better suited for warm climates. If you're still in the planning stages, it might serve you well to do a bit of research before you purchase your palm. By buying and planting a cold-hardy palm tree, you will save yourself, and your plant, a lot of stress.

We recommend reviewing the Arbor Day Foundations U.S. Hardiness Zone Map to determine which plants are best suited for your location, depending on your zone. For example, Zone 3 can experience a low of -30 to -40 degree Fahrenheit; therefore, it's best to grow or move a palm indoors during winter months. If you reside in zones 3 through 6, where low temperatures can range from -5 to -35, we recommend growing your palm indoors or in an area that is large enough for a temporary enclosure.

If you are going to grow your palm outdoors, without any support for your plant during winter months, we suggest doing so only if you're located in zones 7-10.

Winterize Your Palm Tree

If your plant must remain outdoors during cold months, we recommend winterizing your palm tree. By winterizing your tree, you are taking steps to ensure the soil stays moist and doesn't wholly freeze and also guaranteeing the leaves remain warm.

You can wrap your palm in burlap, which will help to retain heat and keep snow and moisture out. Cedar Rim Nursery recommends wrapping your palm in heat tape, then wrapping your palm in burlap, to ensure moisture stays away from the trunk, and it remains warm.
