The greatest chance of destroying a cactus occurs in autumn and winter, when amateur gardeners try to make life easier for plants on the windowsill.
During this period, there is a high chance of making a fatal mistake, because of which you will have to say goodbye to your “green pet”.
In autumn and winter, cacti enter a period of rest. During this period, they are not replanted, not fed, and watered less often than ever.
Temperature
In proportion to the decrease in the amount of sunlight, it is necessary to reduce the amount of watering and the air temperature.
Many gardeners do not know that cactus feels good at -2 … -3 °C. Some species live and thrive at -12 … -15 °C.
The optimal temperature for cacti in autumn and winter is around +5 …+15 °C. Watering is reduced until it reaches a real desert, but only if the room is cool.
Lighting
As for light, you can't keep the cactus in the shade. You need to put the plant on a southern window, providing it with as much light as the weather can provide.
Thus, coolness, rare watering, good lighting and complete rest will allow the cactus to wait for spring without any problems.
