Question: succulent plant temperatures

I would like to know at what minimum and maximum external temperatures can and should be succulent plants thanks hello


Answer: succulent temperatures

Dear Matilde,

with the terms succulent plants (it would be more correct succulent plants) thousands of species of plants are enclosed in a definition, spread all over the globe, mainly in South and Central America (practically all cacti), and in Africa . These plants are perfectly adapted to live in places characterized by low rainfall and so well-drained soils that they quickly allow the water that has fallen with the weather to flow away; in the common imagination, all succulent plants live in hot deserts, with high temperatures all day and all year round.

Actually the succulents live in various climatic conditions, think of the sempervivum aracnoideum, which develops in the Alps (also in Italy), where it finds little water because it grows among the rocks, and during the winter months the little water that it would have available is frozen .

But even the Mexican cacti grow in conditions very different from the Sahara of our imagination: in the arid areas the daily temperature ranges are very high, and often the night temperatures are a few degrees below zero; in addition to this, it considers that much of Mexico is occupied by a plateau, the City of Mexico is located at 2400 meters above sea level, as if to say: it is in the high mountains; therefore even if the latitude makes us think of warm and exotic places, in reality the temperatures in some areas of the globe can be much more rigid than we think.

In fact there are succulents, even cacti, which survive without problems at -12 ° C during the winter months; on the contrary, these plants are much healthier, long-lived and floriferous, if they spend the winter in the cold.

However, we are talking about thousands of genera, each of which brings together various species, each with particular needs.

So it is impossible to give a general rule for the minimum and maximum temperatures that plants can bear; It is essential to recognize the genus and species of the plants we own and to verify plant by plant.

Certainly, however, there is a rule of thumb, which all those who grow succulent plants know: the colder it is, the less water they must have; often those who leave their succulents in the garden in a cold greenhouse, stop watering them already in September, and throughout the winter keep them in areas where they do not receive any type of watering.

In fact, if they are wet, succulent plants tend to rot when they are kept in the cold; to further prevent frost damage, the fertilizations are stopped towards the end of summer, above all avoiding to supply nitrogen-rich fertilizers, which would lead to the development of new fabrics, highly sensitive to the cold.
