It’s a myth that palms can only grow in tropical and subtropical areas, even though the majority of palms may be found in warm climates. Most people are unaware that there are 40 additional states outside Florida where palm trees can be found.
There are countless varieties of cold-hardy palms that can readily endure a 20°F (-7°C) freeze and, unexpectedly, even freezing temperatures below 0°F, but most palms can only tolerate cold to 40°F (-18C). Some of the cold-tolerant palms may grow as far north as Texas, California, Georgia, and Virginia.
Remember that the palm must get fully developed before it can withstand such chilly temperatures. A palm tree needs three seasons to develop itself completely. Given the significant differences between young and mature plants, it’s crucial to understand that palm tree age also has a significant effect in its ability to withstand low temperatures.
As palms get older, they expand their root systems and harden their trunks so they can resist lower weather.
Can palm trees be left outdoors in the winter?
The magnificent and regal Majesty Palm (Ravenea rivularis) originated in Madagascar, a tropical nation. Even though the Majesty Palm is a stunning addition to any collection of plants, it should not be left outside for a lengthy period of time in the winter when the temperature drops to dangerously low levels. Leaving this tropical native outside in winter could be disastrous unless a homeowner has a greenhouse on their property with good temperature control and the right levels of humidity for their Majesty Palm.
The ideal temperature range for a Majesty Palm is between 35 and 80 degrees Fahrenheit. Palm trees can be grown outside without too much trouble by anyone who lives in one of the plant hardiness zones 9 through 11. Majesty palms shouldn’t be kept outdoors in the winter or grown unpotted if you reside in an area where frost or extremely severe temperatures are common. To protect the plant from harm caused by cold temperatures, snow, and ice, it is advisable to bring it inside.
Although resilient and prized for their visually attractive fronds, palms may not survive if exposed to temps 10 degrees below 35 degrees Fahrenheit. When it becomes cold outside in the winter, you may save a palm from freezing by covering its fronds and tying a burlap cloth around the trunk.
Although Majesty Palms make for stunning landscape features, there is a lot to learn about keeping them alive in the winter. To make sure you have this crucial knowledge, keep reading.
How can a palm tree survive the winter?
You could blame it on adventurous gardeners or global warming, but palm trees are growing in unexpected locations. Thanks to the efforts of resourceful gardeners, palm trees are now flourishing in 40 states. With the help of winter-hardy palms, gardeners are bringing a touch of the tropics to places like New York, Pennsylvania, Ohio, and even Michigan. Consider including a winter-hardy palm into your gardening repertoire if you’re prepared to maintain your own backyard paradise.
The secret to growing palms in places where they aren’t common landscaping plants depends on a number of factors. Make sure the palm you choose is rated hardy for your growth zone first. There are several types of palms that can grow naturally in cold climates, such as the mountains of Afghanistan or even Bulgaria. Knowing the lowest temperatures that often occur in your region during a typical winter is also crucial.
Start with the largest plant you can afford and conveniently cover if you want to hedge your chances with winter-hardy palms. A larger palm has probably already been exposed to cold conditions and has grown somewhat tolerant of them. It also has additional food reserves to help it survive the winter and recover if the cold destroys the fronds that are already there. Plant in the spring to give the palm a growing season to take root. To make your plant more resilient to cold weather, use a high-quality palm fertilizer.
Many hardy palm gardeners advise keeping palms in pots their first winter to help them get used to the cold by putting them in the connected garage. Pick a location for planting that is protected from winds, preferably with a southern exposure and especially from chilly north and west winds.
Through the winter, keep an eye on the weather predictions. Plan to take action to safeguard your palm if a drop in temperature is expected. Your choice of defense relies on the size of your palm. The following actions can be taken to safeguard your palm:
Spray Wilt-Pruf or another antidesiccant on the foliage to assist stop moisture loss through the leaves.
- Guard the trunk. It is crucial to safeguard the trunk because it transports water to the leaves. Wrap the trunk in burlap or a blanket and cover it with a layer of heat-producing Christmas lights (not LEDs). The most heat is often generated by C9 lights, but check the packaging to be sure. Some gardeners use bubble wrap on top of a layer of fiberglass-type insulation to wrap trunks.
- Small trunkless palms should be covered in a frost blanket, and potentially some heat-producing lamps.
- Put a layer of chopped leaves on top of the little palms. Don’t entirely suffocate the plant; just cover the base and the crown. During a cold spell, cover the leaf mulch with a box or blanket to protect the entire plant.
- A palm should not be entirely covered (outside of sunshine) for longer than three days.
- At all costs, guard the bud, the developing tip of the palm. Your palm will probably perish if it does. The infections that arise when moist conditions persist are very likely to affect this tip. A few days before a cold snap, many gardeners spray leaves with a copper fungicide to kill any potential disease organisms.
It’s worthwhile to put in the time to look into winter-hardy palm networks online to find out about local palm farmers and get local guidance.

How much cold can a palm tree in a pot withstand?
The lady palm, or bamboo palm, is a little, shrubby evergreen palm with stems that resemble bamboo. This species, which prefers shade, is relatively simple to grow and has dark-green, fan-shaped leaves. It can endure low temperatures of 18 °F. In gloomy areas, it thrives as a foundation plant, an indoor palm, or in mixed shrub borders.
- Native to: Taiwan and southern China
- USDA Plant Hardiness Zones: 9a11a
- : 615 feet tall
- Full, partial sun exposure
Can potted palms be kept outside?
Many emails wondering if palm trees can grow in containers come to me. They can, yes. Numerous palms are actually excellent for growing in pots around swimming pools, on patios, and on porches.
Potted palm trees may be the sole option for many homeowners who reside in colder climates to give their outdoor space an exotic and tropical vibe. Palm trees planted in pots outside need the same conditions for light, temperature, soil, and moisture as trees growing in the ground.
Choose slow-growing palms that can stay in the same container for two to four years because fast-growing palms will quickly outgrow them. Repot them into a bigger container after that.
Look for palms that can survive low humidity and light levels if you intend to bring them inside during the colder months. The ideal palm would have a lovely tropical appearance, be slow growing, small, extremely drought resilient, tolerant of low humidity, and adaptive to low light levels.
You don’t need to worry as much about humidity and light levels if you live in a warm climate and intend to leave it outside all year.
When should my palm tree be covered during the winter?
If your palm is little, you can weigh it down by covering it with a box or blanket. Never keep the cover on for more than five days. A little palm can also be mulched with straw or another material. When the weather starts to warm up, remove the mulch right away.
There are four fundamental ways to wrap a palm tree to winterize it: using heat tape, chicken wire, Christmas lights, and water pipe insulation.
Holiday lights
The simplest approach is to surround the palm in Christmas lights. Use the more traditional bulbs rather than the more recent LED lights. Wrap a string of lights around a bundle of leaves that have been tied together. The tree should be protected by the heat from the lights, and it looks festive too!
Chicken wireFor the chicken wire approach, arrange four stakes in a square with the palm in the center, spaced three feet (1 meter) apart. To make a basket that is about 3-4 feet (1 m) high, wrap 1-2 inches (2.5-5 cm) of fence wire or chicken wire around the posts. Put leaves in the “basket. Early in March, get rid of the leaves.
Insulate pipes
Mulch the soil surrounding the trees when utilizing water pipe insulation to safeguard the roots. Water pipe insulation should be used to cover the first 3–6 leaves and the trunk. To prevent water from entering the insulation, fold over the top. Remove the mulch and wrapping once again in March.
Thermo tape
Finally, you can use heat tape to winterize the palm tree. Retract the fronds and knot them. Starting at the base, wrap the trunk in heat tape, which may be purchased at a building supply store. At the base of the trunk, leave the thermostat exposed. Up till the top of the trunk, keep wrapping. A 15 (4.5 m) long heat tape is required for a palm that is 4 (1 m) tall. After that, cover the trunk in three to four layers of burlap and tape it shut. Wrap the entire thing in plastic wrap on top of everything else, including the fronds. Connect the tape to a ground fault outlet. Just as the temperature starts to warm up, take off the wrapping to avoid rotting the tree.
I can’t handle all that labor. I’m slack. I utilize the holiday lights and cross my fingers. There must be a ton of additional ways to safeguard palms from the cold weather. Use your imagination, but make sure to unwrap the tree as soon as the weather starts to warm up and avoid wrapping it too far in advance of the cold.
After the winter, do palm trees regrowth?
- Unfortunately, there is no way to save a frozen palm tree’s heart after it has occurred.
- In contrast to most plants, palms struggle to resist illness, damage, and to heal wounds.
- Some palm material may survive and be able to grow in the event of a partial frost, but the damaged parts will never recover.
- Brown, sagging fronds can be cut off or allowed to fall naturally.
- New fronds will develop if a palm survives, but it will take some time for them to reach the mature frond size.
- A palm cannot be saved if all of its fronds are brown, yellow, drooping, or fallen.
When ought my palm tree to I bring inside?
Your palm will be protected from the cold by growing in a container and being brought inside for the winter. Before the first freeze, bring it inside, and wait to bring it back outside until all threat of frost has passed. Give the palm a location indoors with strong, directional light. The needle palm (Rhapidophyllum hystrix), which grows to a height of about 6 feet and is hardy in USDA plant hardiness zones 8 through 10, and the windmill palm (Trachycarpus fortunei), which grows to a height of 8 to 10 feet and is hardy in USDA zones 7 through 10, are examples of palms that can be grown in containers.
Do you provide winter water for palm trees?
Newly planted palm trees experience transplant shock and lose a significant amount of moisture. For this reason, I advise watering it more frequently for the first two weeks as they establish and grow new roots.
Your newly planted palm tree needs to be watered daily for the first week, then every other day for the following week before returning to the regular routine. Deep watering works best because the idea is to make sure the water gets to the roots.
A mature palm tree requires irrigation one to three times each week. Depending on the season, adjust how much you water. Palm tree growth increases in the warm months and decreases in the winter. In the winter, once a week of watering ought to be sufficient.
How is a potted palm tree maintained?
Despite their variations, palms require a similar level of fundamental maintenance. You contribute to ensuring their continued health and beauty by attending to their specific demands.
Water: Palms like continually moist soil that is never too wet. Palm fronds that have been overwatered quickly become yellow and brown. Check the soil by hand before watering, whether inside or outside. Dry water that is yet chilly and moist beneath, about a finger’s length deep. To encourage strong root growth, thoroughly and deeply water the plants.
Emphasize container palms more. Plants in outdoor containers that are exposed to the sun and wind tend to dry up more quickly than plants in the ground and may require daily summer watering. Moisture is stored in containers in well-lit interior spaces. They use less water all year long.
Fertilizer: Palms require a particular plant food because of their unique nutrient requirements. Compared to other essential plant nutrients, they may be more susceptible to increased phosphorus concentrations. 2 Lower phosphorus makes it easier for palms to use other crucial nutrients. The middle number on the fertilizer label, phosphorus, which is lower than the other two numbers, aids in preventing nutrient deficits and their signs, such as yellow leaves.
