If temperatures drop considerably in thermometers in the winter nights, and affected the plants on the porch, don’t worry. There some quick solution you can use to prolong the life of frosted potted plants.
Caution and patience
First of all, you need to establish which plants have been affected by frost. You will realize it quite easily, because those who have frostbitten from the low temperatures are withered, they become black and deformed. You will see that the leaves are almost transparent, and the stem becomes brown.
However, if the plant has a woody stem, it’s possible that frost not to destroy the plant completely, and the plant’s root to be recovered.
And patience is the key when it comes to managing the problems of a frostbite plant. Don’t rush in removing those brown parts just to get to the lively-green part of the plant. Trimming the plant stimulates growth, and the next cold will only destroy it. In addition, it will consume a lot of energy to grow, which will make it even more vulnerable.
Leave it for the moment and cover it with a wool fabric or plastic wrap when low temperatures are predicted overnight. In the morning, instead, leave it in the natural light. At the root of the plant you can place a thick layer of straw.
If it’s a potted plant, then shelter it from the very beginning in a very low temperature place. But, pay attention! It’s best to move it on the porch or in a less heated lobby. Under no circumstances put it near the radiator or any other heat source, because the transition will be hard and you risk losing the plant it permanently.
Now, wait until the danger of a new frost passes.
Trimming the plant
After the frost passed, cut off all the affected parts. Don’t be afraid to remove even half of the plant if it doesn’t have enough sap. When it’s warmed by the sun’s rays, it’ll start to grow fast and you’ll be glad you did not ruin it by thinking is not recovered.
For woody plants you have to cut the cracked bark and let it regenerate.
