Maybe you’re one of those gardeners who love Avocados’ creamy texture and sweet flavor. And, maybe you’re also in a headache about how to protect Avocado tree from frost. As we know, Avocado trees are susceptible to frost damage.
Cold weather can cause the leaves to turn brown and curl up, and eventually, the tree will die. However, every problem has a solution or at least prevention. All you need is just a proper guideline. Don’t worry? We’re here to help you out.
Before the cold ruin your lovely Avocado tress, make sure to protect them. Just in time for the holidays, here’s a guide on protecting Avocado Trees from frost.
What is Frost?
Frost is a thin layer of ice on a surface that is colder than the surrounding air, forming as sucrose comes out of water exposed to that surface when the temperature reaches freezing and is immediately followed by freezing.
In temperate regions, the crystal is mainly found on surfaces near the ground as translucent white crystals; in the cold areas, it can be found in a wider variety of types. The propagation of crystal formation occurs in unfavorable conditions by the process of nucleation.
When Does Frost Occur?
Frost typically occurs in the fall and winter, but can also happen in the summer. The temperature has to be below 32 degrees Fahrenheit for frost to form.
It forms on exposed surfaces when there is a moisture deficit, and the air can no longer hold onto its heat. Frost can form quickly in cold environments, but can also take hours or days to form in warm climates.
What Temperature is Needed for Avocado Trees
Avocado trees thrive in warm climates with ample sun exposure. For an avocado tree to produce fruit, the temperature must be above 18 C (64 F) and below 28 C (82 F).
If the temperature falls below 60F, the tree may stop growing. If it gets above 85F, the tree may start to lose its leaves. These subtropical trees need at least 6 hours of sunlight per day.
Prep Work Before the Temperature Drops
Fall is a time when temperature drops and leaves change colors. For avocado growers, it’s also a time to take precautions to protect their avocado trees from the cold weather.
One way to protect avocado trees is by doing some prep work before the temperature drops. So, don’t forget to take the following precautions:
- Plant your avocado trees in a location with mild winters. In areas where temperatures routinely drop below freezing, you can plant your avocado trees in a sheltered spot under a roof or in the basement of an unheated building.
- Make sure your tree is healthy before frost hits. If you notice any signs of disease or dying branches, prune them off before frost occurs.
- Provide sufficient winter mulch to protect your avocado trees from frost damage. Mulch helps retain soil moisture, prevents wind chill damage, and reduces the risk of frost damage.
- Protect your trees from wind by erecting a pole or trellis. Use a metal or plastic rib to attach the pole to the overhead support.
- Maintain a steady water supply to prevent water stress in the tree during cold weather.
- Avoid overfertilizing the avocado tree with nitrogen fertilizer as it can cause leaf drops at this time of year. Rather, you can adjust the soil pH by adding lime or sulfur in the spring.
- Ensure that the soil is kept well aerated and not compacted. Don’t water the avocado tree too much in autumn as it can cause the soil to become soggy
How to Protect Avocado Tree from Frost
Avocados can be grown in a warm climate, but they are most commonly found in areas that have a moderate to cool climate. If you live in a cold climate, you may be wondering how to protect your avocado tree from frost.
There are a few things that you can do to keep your tree healthy and safe during the colder months. Let’s have a look at them:
Cover it with Umbrella
In order to protect your avocado tree from frost damage, you can cover it with an umbrella. This will help keep the temperature around the tree warm and protect it from frost. An umbrella with a needle will work best.
You can make the umbrella out of a bicycle inner tube or buy one at a local garden store. Place the tree in the centre position and cover it with the umbrella. Make sure the umbrella is secured very tightly so that the wind cannot blow it off.
Blankets Or Rugs May Work
One of the most effective ways to protect avocado trees is by covering them with blankets or rugs. These can be placed over the tree and secured with weights or stakes. This will help insulate them from the cold and prevent them from being damaged.
However, the covering should be removed in the morning and left off until evening or when the temperature rises above the freezing point.
Try Wood Boards
One way to protect avocado trees from frost is to use wooden boards to create a barrier between the tree and the cold air.
The best time to put the board in place is when there is a light frost in the forecast. First, find a piece of wood that is at least 2 feet wide and 3 feet long. Cut notches at each end of the board so that it will fit over the tree’s branches.
Next, drill two holes in the center of the board and attach some wire so that you can hang it over the tree. Make sure that the wire is tight enough so that the board doesn’t fall off. Finally, cover the top of the board with some insulation like straw or leaves.
Wrap in Bubble Insulation
If you live in a cold climate, it’s essential to wrap your avocado tree in bubble insulation every winter. This will help keep the tree warm and prevent it from being damaged by the cold weather.
To wrap an avocado tree in bubble insulation, you will need a roll of bubble insulation, a utility knife, and tape. Cut a piece of insulation that is big enough to cover the entire tree.
Wrap the insulation around the tree and secure it with tape. Make sure to cover all of the exposed branches and leaves.
Find Frost Blankets for More Convenience
Frost blankets are special tarps or sheets that you can use to cover your plants and protect them from the cold. Blankets seem to be more reliable in freezing weather to protect Avocado trees from potential damage. They work by trapping heat around the plant, which helps keep it warm during colder weather.
To use a frost blanket, first determine what size you need. Most frost blankets are either 5’x8’ or 6’x10’. Next, spread the blanket out on the ground next to the plant and drape it over the top of the plant.
Make sure to tuck it in around the bottom of the plant so that there is no air gaps. Finally, weigh down the edges of the blanket with stones, bricks, or anything else you have handy.
Add Christmas lights
Christmas lights are often used to decorate homes and businesses during the holiday season, but they can also be used to keep your avocado tree alive in the winter.
By stringing the lights around the tree, you create a warm and inviting environment that will help your tree stay healthy and happy.
These lights will also help to keep the avocado soil warm, which is important for the tree’s growth. Use a high-quality light set, like LED lights, to avoid overheating the tree, and they’re also better for the environment.
The lights should be placed around the tree in a circle and turned on for at least four hours. And be sure to check on your tree regularly to make sure it’s staying healthy. However, if you don’t know how to wrap the tree with lights, follow these steps:
- Select a well-lit area that receives full sunlight, either on the south side of your home or outside.
- Cut the Christmas lights to fit around the branches of your avocado tree and wrap them in a clockwise pattern. Make sure they are not too tight as they will restrict the flow of water.
- Wrap the bottom portion of the light-filled tree with a secure plastic wrap to prevent water from leaking out.
How to Reduce Risk of Frost in Avocado Tree
Here are 6 tips to reduce the risk of frost in Avocado trees:
- Keep your avocado trees well-watered. A dry plant is more likely to freeze.
- Mulch your avocado tree with something like hay or straw. This will help protect the roots from freezing and moisture loss.
- Protect your avocado tree from strong winds by using a windbreak or fence.
- Plant your avocado tree in an area that will receive plenty of sunlight and warmth, such as partial sun or part shade.
- Don’t over-fertilize your avocado tree; this can create an abundance of foliage that can lead to frost damage.
- Never prune your avocado tree during the winter.
