While winter hardy palms may withstand temperatures as low as -40 degrees Fahrenheit, tropical palms may be damaged by the cold. Palm tree owners in warmer regions typically aren't concerned about frost damage. However, given the erratic nature of winters over the past few years, subzero temperatures should be expected.
Tropical palm trees cannot withstand temperatures below 45 degrees Fahrenheit, while cold-hardy palms can. The rate at which the temperature lowers is crucial. Even the toughest palms will suffer damage if the daytime temperature is in the 60s and 70s but drops to the mid-40s at night.
However, palms are better able to withstand lower temperatures without substantial harm if the temperature is allowed to gradually decrease over several days.
Factors such as the palm's cold resistance (cold hardiness), when it was planted, how old it is, how healthy it is, how much fertiliser it receives, and where it is located in the yard all have a role in determining the extent of the damage. Cold, dry winds, the drying effects of the midday heat, and the persistence of the chill all contribute to making the situation worse.
A palm tree needs three growing seasons in a temperate zone before it can be considered completely established. Perhaps even more time will be required if the soil is composed of a lot of clay.
Perhaps you're wondering, "Can palm trees withstand the snow?" if you already own palm trees and are thinking about getting some. People often enquire as to whether or not palm trees can survive in colder climates, despite the fact that they are quite resilient plants. This article addresses the question as to whether or not palm trees can endure snow, as well as the coldest temperature at which such a plant can persist.
It may come as a surprise to find that palm plants can actually thrive in cold climates. There are palm tree species that can survive in snow for brief periods of time or that can be "winterized" so that they can survive the cold all year round.
A chilly temperature can only be tolerated for a short while, even if cold-hardy palm trees do exist. If you want your palm to survive the freezing temperatures and snowy conditions of winter, read on!
Numerous palm trees that can withstand freezing temperatures are readily accessible. True palm tree flora can be found even in colder regions, including such Southern Asia. The fan palms in the genus Trachycarpus are widely considered to be the hardiest palms in cold climates.
Its Trachycarpus fortunei, also called the Windmill palm or the Chusan palm, as well as the Trachycarpus takil, sometimes called the Kumaon palm, are the most prevalent of these species. A mature Windmill palm can reach heights of 12-20 metres. It has spread effectively over the world from its native Southern Asia. The Kumaon palm is found naturally only in the Himalayas and can reach heights of 10–15 metres.
5 Ways To Restore A Freeze-Damaged Palm Tree
Winter's effects may not become apparent for several weeks or months. The palm may appear healthy at first, but subsequent leaf growth may be misshapen and partially discoloured.
The condition of your palm and the necessity for replacement can be evaluated even by end of spring. Let's move on to other things you can do.
Step 1. Cleaning
The severity of the wound must be assessed first. You can assess the level of damage by gently tugging the spear's tip out of its hole. At other instances, the newly installed spear is firmly anchored yet can be easily removed. If that happens, just fill the hole with water and flush it out.
To prevent the rot of new growth caused by water accumulation, drill a tiny hole just below the leaf bases. See whether bud has died or not. If it's still green, there's hope for the palm tree. Put away the fork if it's mush and get a shovel.
Step 2. Spray Copper Fungicide Liquid
The next step is to safeguard the palm from fungal and bacterial infections. Apply some Liquid Copper Fungicide on the palm. Palm trees are more susceptible to bacterial & fungal infestations following the stress of the frost.
The one-of-a-kind formula of copper fungicide is effective against both. No further than twice, with a 10-day interval between applications, is recommended. Use the full intensity of the spray to thoroughly drench the palm bud with liquid copper. That way, microbial rot of buds should be less likely to occur.
An effective method for preventing the spread of root infections in palm trees is to apply Copper Fungicide all around palm's base. Liquid Copper Fungicide from Southern Ag is one of the products I've discovered to be really effective. It is effective against yeasts and bacteria.
Step 3. Pruning
Do not prune the fronds for at least a couple of months. In order to encourage the bud completely dry out, remove any and all dead leaves from around it. Leaves that are beginning to brown at the tips should be left alone as palms can still use the nutrients to grow new leaves.
Try to avoid excessive pruning at all costs. If you cut off all the palm tree's green leaves, it won't be able to generate as much food. If you cut off too many leaves, you'll simply make things worse.
Step 4. Spray Antiperspirant
As we said before, the palm's ability to deliver water to its leaves may be impaired by cold injury to the trunk tissues or roots. To prevent water loss from of the plants in the cold, spritz your hand with anti-transparent spray.
A clear film is formed on the plant's foliage when the antibacterial transpirant spray is applied, preventing water from evaporating and easing the plant's stress. We prefer applying a spray made by Bonide called "Wilt Stop" to guard palm trees from of the cold at the start of the cold season.
Step 5. Fertilising
In other words, you shouldn't fertilise the palm trees just yet. To be safe, hold off until the end of summer or early October. When individuals detect browning leaves, they typically begin fertilising immediately. Compost and manure are NOT plant food.
Fertiliser, often known as "Palm Food" or "Plant Food," is a nutrient blend used to increase soil fertility and stimulate plant development. Hydroponic plants use water, carbon dioxide, and sunlight to create their own sustenance.
The fertilisers are similar to multivitamins for plants. Vitamins won't heal a person who is already unwell, diseased, and nutritionally deficient. A diseased palm tree is put under even more strain when you fertilise it and expect it to begin growing again. Apply a sluggish fertiliser in the late summer or early spring. Please refer to my post on fertilising palm trees for further information.
Frequently Asked Questions About Palm Tree
The solution is to wait until winter and prune again using thinning cuts or reduction cuts. The former takes out an entire branch at its point of origin on the trunk, while the latter cuts a branch back to a lateral branch. Making the wrong cuts – The ultimate in bad pruning moves is to top a tree.
You can keep oak and cherry trees small, too. Your arborist will help develop a plan to ensure you're training your tree and reducing its height in the best way possible. They'll also pinpoint the best time to prune because cherry and oak trees are on opposite pruning schedules.
Repeated removal of large amounts of foliage can cause a decline in tree health, or even worse - the death of a tree. When too much foliage is removed from the upper canopy of a tree, excessive exposure of bark tissue to the sun can result in “sunscald” or damage to the bark and the underlying vascular system.
Trees and shrubs that bloom during summer and into autumn are best pruned in later winter or early spring as soon as their annual growth begins. Refrain from fall pruning because it stimulates new growth that could be killed by winter cold.
Autumn pruning your plants can have a huge impact on how they grow next year. It keeps them healthy, vigorous, and balanced and stops large varieties from taking over the garden. Autumn is the perfect time of year for trimming!
Winter Palm Tree Damage Comes In Three Forms
Your palm is susceptible to cold, frost, and freeze damage this winter. The bud of a palm tree is both the most vital and susceptible section of the tree. New leaves sprout from the bud. In the absence of substantial damage to the palm's bud tissue, the tree should recover and begin generating new leaves by the following summer.
Emerging leaves may be aberrant, with some showing signs of malformation or browning. It could be six months to a year before the palm tree fully recovers from the freezing. Damage to the bud tissue could be fatal for the palm.
Cold Damage To The Palm
Older fronds may curl and turn a yellowish brown colour if the palms has been injured by cold. It's possible that the rate of expansion of the brand-new growth that will emerge in the next months will be lower than average.
It's possible that some of the brand-new spears won't function properly. These conditions are the result of the unusually cold weather and will disappear as the temperatures return to normal.
Palm Frost Injury
Palms, particularly those with a low cold tolerance, can be severely damaged by frost. Typically, it spreads over a whole plant's foliage, wreaking havoc on the leaves and even the bud.
In the days or weeks following a frost, the fronds may develop a significant discoloration, often appearing black. It looks like you have some major damage.
Palm Freeze Injury
Most tropical palms will perish at temperatures of 32 degrees Fahrenheit or lower if they are not protected throughout the winter. If the palm is subjected to the frost for an extended period of time, it will lose most of its leaves, if not all of them.
Vertical fissures on the trunk as well as the crownshaft may become apparent several months or year after the frost. The trunk bending, unpleasant odour, and soft crown just below the spear all are signs of serious trauma.
If the tree's trunk tissue is damaged by freezing temperatures, it will be unable to transport as much water to its leaves. When cut down, palms cannot regrow their trunks like other trees may. The crown collapsing could be an indication of this kind of injury.
How Can I Protect Palm Trees From Future Freezes?
If you take the following precautions, your palms will have a far higher chance of surviving a winter freeze:
- Only palms that can thrive in your region should be planted. Learn your region's planting zone right here!
- Protect your short palm trees from the impending frost by carefully wrapping them in a blanket or sheet. Get in touch with an arborist if you want to wrap back fronds of a tall palm around the trunk. Once the danger of frostbite has passed, take off the cloth and unwrap the fronds.
- Mulch around your palm tree to keep it moist and make sure it doesn't freeze.
- In order to keep your tree healthy, you should fertilise it on a regular basis. Fertilizer's nutrients may boost tree vitality and cold resistance.
If you anticipate more chilly weather, it's in your best interest to keep your palm covered. In my in-depth post "10 Ways to Protect Greenery From Winter Freeze," We explain every strategy you may employ to keep your palms alive during the winter. There are a variety of simple methods you can employ, such as:
- Fertilisation. One of the greatest methods to get palms prepared for the cold is to provide the correct nutrients with in months prior to the winter season.
- An Abundance of Mulch Keeping the tree's roots from freezing is as simple as mulching them with 4 to 6 inches of material.
- Heavy precipitation. Providing the plant with extra water before to a cold snap can help prevent the root from freezing.
- Use of an antiperspirant spray. It wraps the leaves in a transparent layer that prevents water from evaporating.
- The Fungicide Copper. Infectious diseases caused by bacteria and fungi are countered.
- A Cozy Blanket. Wrap your hand in a blanket, burlap, or something similar to keep it warm.
- Tree and Leaves of a Palm Wrapping. Tape a warm blanket or other cloth around the palm's trunk and over its canopy.
- Lights, as well as a heater. Extra heat might be provided by a butane stove or holiday lights.
- Heater cords. They include a constructed thermostat and may be placed either at the tree's base or its main stem.
- Preserve vegetation in a temporary glasshouse. Make a wooden frame to fit snugly over the tree, and then cover it with two layers of plastic, nailed together.
Signs And Severity Of Palm Tree Cold Damage
We made this infographic to help you identify the various forms of winter damage. With such a mild case, the palm should be able to recover by the following season. A medium-severity event has a 50/50 risk of causing severe injury. High levels of severity very certainly spell death for your palm.
Evidence of Wear and Tear:
- A mixture of green and brown, new growth
- The rate of expansion is slow.
- Expired leaves are a brownish yellow colour.
- Curling, old leaves
- Brownish or blackened leaves indicate that they are old.
- New development is misshapen.
- Easy to rip out new growth
- Brown or black new growth
- The crown is squishy and spongy.
- There are vertical splits in the trunk.
- Putrid smell emanating from the trunk or flower buds
- The trunk collapses or bends
Plant Winter-Hardy Palms
Some palm plants can't handle the cold. There are others that thrive in hotter climates. It would be wise to learn as much as possible about palm trees while you're still in your planning stages. Purchase and grow a chilly palm tree to relieve stress on both you and your tree.
The Arbor Day Foundation's Hardiness Zone Map might help you figure out what kinds of plants can thrive in your area. If you live in Zone 3, where winter temperatures can drop to -40 degrees Fahrenheit, you should probably bring your palm within during the colder months.
If you live in zone 3–6, when winter lows can dip to -5 or –35 degrees Fahrenheit, you should cultivate your palm inside or in a space large enough in a temporary inclosure.
Zones 7–10 are ideal for growing palms outside without protecting them throughout the winter.
Prepare Your Palm Tree For Winter
It is recommended that you winterise your palm tree if it must endure the outdoors during the colder months. Winterizing your tree is taking care of it so that the soil doesn't dry up and completely freeze, and so that the leaves don't drop off in the cold.
Wrapping your hand with burlap can prevent snow and moisture from penetrating and will keep your hand warmer. Wrapping your palm with heat tape and then in burlap, as suggested by Cedar Rim Nursery, will help keep moisture off the trunk and maintain a comfortable temperature.
Keeping your palm tree at an ideal temperature can be achieved with the help of heat lamps or Christmas lights. Assuming they aren't LEDs, the Christmas lights you use to decorate your tree will emit heat (they will not produce heat).
Alternately, depending on the dimensions of your tree and the available room, a heat lamp may be the ideal solution. See here for an in-depth analysis of the 12 most popular heat lamps on the market today:
Make Use Of Indoor Space
By enclosing your palm, you can keep it safe from the wet and cold of winter. Having your tree contained is as simple as planting it in a pot and taking it inside. A shed or carport with windows would do nicely.
Before the ground freezes, you should try to create a glasshouse if you are unable to move your palm.
Those with no gardening experience at all can find a lot of success with the Palram Greenhouse. Winds reaching up to miles an hour are no match for it, and plants benefit from the easy passage of light. Reviews
We really appreciate Palram's high quality and reliable customer service.
Don't freak out if your palm shows indications of freezing because it didn't survive the winter. Your palm may be treated and preserved. Assess the damage to your palm tree as soon as you become aware that it has been exposed to bad weather. Any injured leaves will likely deteriorate further over the next few months as the cells die off.
Leave the damaged leaves alone. What portion of the crop was lost won't be known until April. Then you can trim away the fronds or dead leaves. Spraying a fungicide on any probable illness is a good idea. A spray for illness prevention has been recommended.
In order to prevent the spread of fungi, use Bayer Advanced Disease Management for Rose, Floral, and Shrubs. Every three weeks or so, spray at the crown and on any damaged areas.
Palm trees may or may not be able to endure an outdoor winter, depending on the temperature. There are a few items you can do to help your palm tree through the winter if you have it planted out onto your property and can't bring it inside.
