There is no straightforward answer to this question because it depends entirely on the type of plant that has been frozen, and the intensity of the freeze.
Plants are living creatures, so it is understandable that they struggle in freezing temperatures, just like humans do. So, if your plant does get frozen, you cannot expect it to bounce back immediately.
If your plant has had a light freeze, then more often than not you will be able to bring it back from this. The plant might struggle for a little while, and you might find that it loses the majority of its leaves.
But, with some gentle nursing, and tender care, you should be able to restore your plant to full health. However, you might not notice that the plant has fully recovered until the spring rolls around and a new group of leaves begins to grow on your plants.
However, if your plant has had a hard freeze, then the chances of recovery are much slimmer. If your plant has had a hard freeze, then it has probably been frozen for a very long time, and this will limit the chances of it recovering.
Plants contain a lot of water, so when they undergo a hard freeze, the water inside the plant will also freeze. In a hard freeze, this can cause irreversible damage, which is why most plants do not recover from a hard freeze.
But, it is always worth giving saving your plant a shot, even if you think you will not be successful.
Can plants recover from cold shock?
Cold shock is fairly similar to a light freeze, so, in a lot of cases, you will be able to save your plants if they have gone through cold shock. Just like with light freezing, you will need to put a lot of effort and hard work into saving your plants.
But, more often than not, you will find that plants that have gone through cold shock will make a full recovery.
When you have a plant that has gone through cold shock, you might find yourself avoiding watering it. When your plant is in a bad way, you might want to handle it with delicate hands to avoid any more damage.
But, if you do not water your plants that have gone through cold shock, then they definitely will not survive. So, ensure that you give your cold shocked plants lots of water to help revive them.
If your plant has gone through cold shock, then the best way to aid its recovery is to go back to basics. To survive, plants need water, warmth, and light. So, if you want to save your plant’s life, you need to give it all of these things.
Keep it warm to help ease the freezing, give it sunlight so that it can get lots of nutrients, and give it water to prevent it from drying out. If you go back to basics, then you have the best opportunity of saving your cold shock plant.
How do I know if my plants have frost killed them?
You might expect it to be difficult to identify plants that have been damaged by frost. However, this is actually very easy to do as the symptoms of frost-damage are clearly visible in plants.
This is mainly because the effects of frost damage kick in very early on in plants, so their symptoms are easily noticeable. Then they just become more noticeable the longer the plants are exposed to the frost.
If your plants have been exposed to frost, then you will be able to identify this easily. You will notice that the growth pattern of your plant quickly becomes very slow and sluggish. In fact, you will probably notice that the plant isn’t growing at all.
Additionally, you may find that the once green leaves of your plants go limp and translucent, while the leaves of an evergreen plant will turn brown from exposure to frost.
Over time, the leaves will continue to wilt further, until they turn black, crispy and fall off. But, you will usually spot frost damage before this.
As long as you spot the frost damage before the leaves turn black and fall off, then you will usually be able to save your plants. However, if you do not spot it until after this, then the chances do begin to deteriorate.
This is because the black parts of the plant have died. But, as we have said, you will usually spot this issue prior to that, giving you plenty of time to save your plant’s life.
Will my plants come back after a hard freeze?
If your plants undergo any sort of freeze damage, then you should hope for a light freeze. This is because a light freeze is easily reversible, but a hard freeze is a lot more difficult to save. In fact, most plants that undergo a hard freeze do not make it out alive on the other side.
A hard freeze penetrates the water inside your plant, which can cause damage to the internal mechanisms of your plant.
But, a hard freeze isn’t necessarily a death sentence. As we said earlier, some plants are hardier than others, so if it is a hardy type of plant that undergoes a hard freeze, then you might be able to save it. In particular, evergreen plants have the best chance of being saved from a hard freeze.
If you do not think that the hard freeze has killed your plant, then you can attempt to save it by going back to basics. Just like you would when saving a plant that has gone through a light freeze.
So, to try to save your plant that has gone through a hard freeze, you should focus on 3 things: warmth, water, and light. In the winter it can be difficult to get light, but warmth and water are easy to get access to.
Give your plant plenty of water and lots of warmth, and you might be able to save your plant that has been hard frozen.
