After researching what to do when an aloe vera plant has frozen, I found a lot of useful information out there on this topic. Therefore, I have written this post which includes the many options which exist if an aloe vera plant has frozen.
Unfortunately, freeze damage is a severe problem for aloe vera plants. Whether it can recover depends on the amount of time the plant has been exposed to freezing weather. If the plant turns entirely brown with a squishy consistency, it is probably damaged beyond repair. However, if you can see some surviving green leaves, it might be recoverable.
Read on to know the reason why aloe vera plants are susceptible to the cold, as well as what you can do to solve and prevent those from happening again.
Reasons why aloe vera is susceptible to damage from the cold
Aloe vera is a plant known to originate from the Arabian Peninsula that thrives in both tropical and semi-tropical climates. In hot climates, the plant can thrive outside all year round and peak during the spring and summertime in most areas.
They are often grown by many gardeners due to their many amazing properties, spanning aiding personal hygiene to health and wound relief and even to freshen up your garden. More about that is covered in this detailed article that I wrote on aloe vera benefits and even their harvesting, linked through here.
However, in colder weather, several factors make it hard for the plant to survive.
Ale vera plant components and why they are susceptible to freeze
The leaves of an aloe vera plant contain a gel that is clear and basically composed of water. This gel does include certain glycoproteins, but it is around 99% water.
This fact explains why the plant is not capable of withstanding freezing temperatures. The chemical content of the plant means that if it is left outside in the cold, it will easily freeze due to the high water content of its leaves.
If proper precautions are not taken, the gel-like substance inside the leaves will succumb to the cold and freeze. The only question which remains at this point is how much damage has been done?
How to tell if the aloe vera plant has been damaged by frost
A few clear signs indicate that an aloe vera plant has been subjected to frost damage. Its leaves will usually turn to brownish or yellow color, and the consistency of the leaves will turn squishy and mushy.
Another sign that the frost has damaged your aloe vera plant is that the leaves start to have a certain glassiness to their appearance.
This is caused by the tender, soft tissue of the plant being killed by frost and is usually followed by inevitable rot and the death of the healthy parts of the plant.
These symptoms will be initially visible on the outer leaves of the aloe vera plant. The inner leaves are more likely to retain their natural green complexion because the frost generally takes more time to reach them.
If the core of the aloe vera plant is still looking fairly healthy, this is a good indicator that it could be saved.
The stages of cold damage in aloe vera plants
There are two types of damage done to an aloe vera plant when exposed to cold weather. These can be categorized as either frost damage or freeze damage.
I will explain these two in more detail below, but in short, if an aloe vera plant has frost damage, there is a good chance it can survive with the necessary treatment. On the other hand, if the plant has freeze damage, this is more likely to render it impossible to save, and the best option is to dispose of it and start again with a fresh plant.
Frost Damage in aloe vera plants
Due to aloe vera being a delicate plant and its natural habitat being warmer climates, it’s no surprise that it struggles to survive in the cold weather.
Frost damage occurs when the plant is exposed to temperatures that drop below 40 degrees Fahrenheit.
Thankfully, when frost damage occurs, the aloe plant won’t necessarily die. Don’t be too alarmed if the leaves have turned brown and began to shrivel; as long as there is some green left on the plant, there is a chance that I can be salvaged.
Freeze Damage in aloe vera plants
Freeze damage is a more serious matter than frost damage. If succulent plants like aloe vera are kept below freezing temperature for hours on end, there is a strong chance they will not be able to recover.
A tell-tale sign of freeze damage is the leaves turning black, becoming crisp and shriveling up over time.
A frustrating part of freeze damage is that you will have to wait for a few weeks and observe the plant to see if the damage has penetrated too deeply for recovery to be possible.
Whether the aloe vera plant can recover or not essentially depends on the amount of time, it was exposed to freezing temperatures. A few hours is the limit, but if it has been a whole night, the chances are it will not recover despite your best efforts.
Things you can do if your aloe vera plant has frozen
In this section, I will go into the options you have when dealing with a frozen aloe vera plant and how to get the best outcome from the situation. In an ideal world, this information will give your aloe vera plant the best chance of recovering and thriving once again.
Let’s start with the bad news. The reality is that aloe vera is not a particularly durable plant and is not well suited to colder climates.
If temperatures drop below 40 degrees Fahrenheit, the aloe vera plant will struggle to cope with the cold.
All that we can really do when our aloe vera plants are frozen is give it some care, then hope for the best.
Check the amount of frost on the aloe vera plant
If the plant had just a touch of frost, we could remove the damaged leaves, and it will usually recover in a short period of time. If the whole plant has succumbed to the frost, it is probably time to get rid of the plant and start afresh with a new one.
Check the leaf color of the aloe vera plant
The only real way to know whether the damage done by a frost is fatal to your aloe vera plant is by examining its appearance. If the leaves have shriveled and turned a brownish color, but some of the leaves remain green, there is a good chance that they can be saved.
If the whole plant has turned brown after spending a significant amount of time in freezing conditions, unfortunately, it is likely to be unrecoverable.
Set aside and stop watering the aloe vera plant
The aloe vera plant is especially susceptible to damage from the cold due to its natural growing climate being warm. It is not biologically adapted to dealing with frosts due to its natural ability to retain a large quantity of water.
This is why it is a good idea to put the plant aside and resist watering it for a week or two if you suspect frost damage.
The soil will remain moist for a long period, so watering it further would actually hinder its recovery.
Aloe vera is a succulent plant – meaning it doesn’t require much water and will not respond well to moist soil. This explains why frost can be so damaging to the plant. The following section will look further into what measures can be taken when an aloe vera plant has been exposed to freezing weather.
Revival techniques for aloe vera plants
Now that we’ve got the doom and gloom out of the way, it’s time to discuss some of the techniques you can use to revive your aloe vera plant, providing the damage done by the frost isn’t irreparable.
Consider pruning your aloe vera plant
Usually, the recommended time for pruning an Aloe Vera plant is after the April flowering season, in May.
If the aloe vera plant has been exposed to frost, then pruning the plant earlier than expected may be the only way to aid its survival.
Using a sharp knife, we can remove the obviously dead and discolored leaves from the plant whilst being careful not to cause further damage to the parts which are still green and healthy.
Place your aloe vera plant in a warm environment
After removing the affected leaves, it is really a case of keeping the plant in a consistently warm environment and revisiting the temptation to provide it with water.
Over a period of weeks, it will become clear whether the aloe vera plant is on the road to recovery, as new leaves will appear and the brownish color will gradually disappear.
Consider using agricultural sulfur
Another technique that may help revive the plant is to dust the cuts made from removing the bad leaves with agricultural sulfur.
This, combined with not watering the plant for a week and finding a warm spot out of direct sunlight, is the best effort you can make to keep it alive.
Aloe Vera plants can be grown easily and propagated providing that you follow some basic information. The video below will provide that information about tips for growing Aloe Vera and how to avoid any other problems besides freezing your Aloe Vera Plant.
Conclusion on aloe vera plant freezing
If your aloe vera plant is looking worse for wear after being frozen, removing the damaged parts of the plant and leaving it for a week or so is a good idea. It would help if you did not water it during this period, which may harm it further.
Hopefully, the plant will slowly recover, and you can start to give it small amounts of water if there are signs of re-growth.
When they do under your watchful care, you can slowly boost their growth process by looking into their soil needs, sunlight hours, and possible fertilizer needs, which are explained in this article of mine on caring for aloe vera plants. Feel free to check it through here.
