Plant that has suffered from the cold
Cold damage can be related to different circumstances. First of all we distinguish the species cultivated indoors (or many succulents) from those more properly "from the garden" and therefore kept outdoors, perhaps in the open ground.
The former are usually much more delicate because they originate from the tropical or equatorial areas of our planet: this means that, in most cases, the first damage is already evident when it drops below 10 ° C.
The others, if chosen carefully when designing, should instead be suitable for our climate. In this case the damages are due in some cases to particularly cold vintages or to late frosts, when the plant was already in vegetative restart. Here are some suggestions on how to deal with these events.
Indoor plants: only a few discolorations
During the summer, many of us are used to putting houseplants outside: thanks to the “natural” rain and the intense lighting, it pushes them to grow quickly, giving us great satisfaction. However, it can happen that the cold, especially at night, suddenly arrives causing leaf burns and drying out. In these circumstances, a common mistake is to move the specimens suddenly to a very hot room: these drastic changes are only further stress for them. Instead, it is necessary to act gradually putting them first in a room with a constant temperature of 15 ° C and, before further movements, wait for a minimum recovery. Important is to irrigate often, but slightly: the cold, especially if associated with the wind, causes dehydration. Instead, we stop fertilizing.
