The cold and, above all, frost can cause significant damage to the most sensitive plants , to the point that their leaves can burn. If that happens, unfortunately most of the time all its parts end up rotting: the branches, the trunk and the roots.
Can anything be done to prevent it? Yes of course, but we have to act as soon as possible. So let us know how to recover frozen plants .

Identify cold symptoms in your plants
To know if a plant is frozen, the first thing we have to do is, of course, identify it. We must observe how it is after having spent a few cold days . Sometimes it will be enough that you have had a bad time one night so that the next day it looks bad, but it can happen -especially in palm trees- that the damage does not show up until the good weather returns.
What are those cold symptoms? Basically the following:
- Appearance of yellow dots on the leaves (occurs in newly purchased Cycas ), or reddish.
- Cacti and succulent plants turn reddish.
- The leaves dry out, having brown spots that quickly turn black.
What can be done to recover them?
Once we have identified the symptoms of cold in the plants, we have to start doing some things in order to recover them as soon as possible. Thus, with scissors previously disinfected with pharmacy alcohol we have to cut all those parts that are affected . Succulent cacti and plants will only be treated if they are soft, in which case we will proceed to cut them clean with a previously disinfected knife, and let the wound dry for a week and then plant it in a pot with sandy substrate (such as pumice).
We also have to do is protect the plants , either inside the house in a room where a lot of light from outside enters, inside a greenhouse or by wrapping them with a thermal blanket first and with transparent plastic later. Around the trunks we can put a mulch of leaves or bark so that their roots can better withstand the conditions. In this way, if there is frost again, they will hardly notice it.
Lastly , it is highly advisable that we treat them with a fungicide . Fungi are microorganisms that will not hesitate to infect a weak plant. But if we treat them with this product, we can rest easy.
With these tips, your plants will surely come out ahead.
