How to grow the grusone
These cacti are cultivated in the typical way for most cacti, they keep in a well luminous position, possibly sunny, with a summer shade seeds, during the warmest hours of the day; they prefer a very well drained soil, formed by mould mixed with sand, pozzolan, or lapillus, in way that the drainage is excellent and that the substratum does not keep too much humidity.
Watering is provided only when the soil is perfectly dry, and only during the periods when the plant is kept in place with temperatures above 15 ° C.C.
I grusoni are grown in the garden, from March-April to September, or also on the terrace, in a very luminous and well ventilated area; when autumn arrives, watering is suspended and if the plant is placed in a sheltered place, where the temperatures are over the 7-10°C, then in a cold greenhouse or in a stairwell.
Let’s avoid cultivating these cacti in an apartment all year round, because the light is definitely too little, and with the passing of the years these plants tend to mummify, or at least to develop in an unhealthy and pleasant way, and to be attacked by parasites or diseases.
Not all of us can afford a greenhouse, especially if it is heated, but often, for a large pole, it is sufficient to place it on a balcony facing south or east, with the walls of the house behind it as protection and without watering; to try to survive our grusone left outdoors, first of all let’s stop watering and the ground already in September-October, then place the pot in an area where it does not receive rainwater, so that the substrate can remain dry until the end of winter, in case of intense frost, we cover the plant with agritourism, even in several layers if we believe that the temperatures will be very low.
These plants develop very slowly, and have a fairly small root system, for this reason it is not necessary to intervene with repottings too frequently.

The problems of cacti
Typically, those who cultivate a couple of cacti at home go against typical problems, which are repeated and reoccur over the years, certainly these plants are particularly prone to attack by particular pests, but often very significant infestations and problems of all kinds are favored by the method of cultivation.
In nature, cactuses are used to surviving in environments with a very unfavourable climate, with temperatures even above 50 ° C, which at night can drop even below zero; little or no rain for long periods of time, strong sunshine.
This cause sometimes tends to adapt to the climate of our stay: 20 ° C throughout the year, almost no temperature range between day and night, no rainfall for years, no mineral salts in the ground, lack of light and air exchange.
Therefore, it often happens that these plants manage to survive for years in conditions not very favourable to the life of the plants; and after years of suffering, they meet a very rapid decline, caused by a parasite, or by an airstroke, or by a sudden abundant watering during the winter.
In order to better cultivate a plant, it is always advisable to know its living conditions if it is transported to its place of origin.
The grusoni, like many succulent plants, can survive long periods of drought, using the water they store in their tissues, but they cannot live without water forever; therefore from May to September we water regularly, when the soil is dry.
This means that the large grub that we keep on entering in May will need one watering per week; however, if we move it in the garden, in full sun, in June, it will need watering every two or three days, because the air and the sun will completely dry up the bread of earth around the roots.
Poor ventilation encourages the development of cochineals and mites, which can damage the roots and stem of the plant.
Excessive watering can favour the development of rottenness and mould, especially if supplied during the winter.
A scarce insolation can favour a phenomenon called etiolation: the plant, deprived of the sun light, turns yellow, due to the lack of production of chlorophyll, and in search of the light it develops in length in an unpleasant way, assuming strange forms and often producing soft and unhealthy tissues.
Mother-in-law’s pillow: Some advice
So if we can avoid growing our succulent plants always at home, always in the same position, if possible we prepare shelves on the balcony, where to shelter the plants in summer, but also in winter, with a cover of agritourism, to prevent them from being exposed to intense frost.
Let’s remember to water the plants placed in the sun, every time the soil is dry, from April to September; let’s avoid watering instead for all cacti grown at home, and especially those grown in greenhouses or outdoors: the colder it is, the less water they want.
We provide the right brightness: in nature, cacti develop in arid places, without broad-leaved vegetation, and therefore enjoy very few hours of shading per day, and only if they develop next to a rock.
