In the nature of cactuses are forced to survive in extreme conditions, and this well-known fact, alas, does not always benefit them at home. Taking the needs of these ascetics too literally, lovers of indoor plants themselves without suspecting it creates them problems.
Yes, the care of cactuses is not common compared to the needs of violets or, say, kalata. On the other hand, if you find a common language with them, you will be surprised to find that it is much easier to treat them than with the rest of the window sill dwellers.
Watching from the outside, I have long noted for myself two “camps” of florists, who have not yet become acquainted with the needs of cactuses. The first, believing that in the deserts and steppes, nature does not allow plants to “turn around”, take care of them, like all other flowers. The second, betting on their ability to survive, forget about irrigation and other moments. Let’s find out why neither one or the other can’t please the cactuses.
Most of us are used to watering geraniums, jewelry and senpolia every day or every couple of days. For them, this is normal, but for cactuses it is fraught with rot. In their natural habitat, the only solution is slow metabolism: rainfall is rare, and rapid growth will require too many resources. In the “economy” mode, the cactus is always ready to wait until the next rain, because there will be a small amount of moisture in its stem.
If there is too much water, the plant continues to accumulate it by habit, but the growth rate is too low to use up this moisture. Cracks appear on the stem, which is a direct path to rot. The cactus roots, which are used to regular “drying”, suffer from the lack of oxygen and begin to die off. Only if they dry out without long watering – the plant drops the ballast, which requires nutrition in a difficult period, in this case, they simply rot.
Complete absence of watering also does not have a positive effect. Yes, in the deserts sometimes no rain for several months, and you can easily leave this care for the vacation period. However, even a cactus runs out of water in the stalk sooner or later. The stem is gradually shrinking, and for some time this is normal, but the green body just needs a break.
Tip: Let the earth dry completely and spend a couple of days without water. Leave the watering can aside if you see that the ground is still wet. The easiest way to understand is that it’s time to water the cactus, by the weight of the pot, or visually – by a slightly smaller stem.
Summer and winter
All plants have a period of rest, only we do not always suspect it. It’s easy to notice the hibernation of cyclamens or dioxins, because they are dropping their leaves at this time. Other plants just take a break from flowering. Cactuses are no exception: from November to March, when the day gets short, the metabolic rate drops to a minimum. Most species during the rest period is better not to water at all and if possible reduce the temperature to 13-15 degrees. Otherwise, you risk facing the same problems that excessive watering causes. In addition, restless cactuses are unlikely to find the strength to bloom.
In summer, watering during the midday heat is especially dangerous: pots heat up in the sun, and in a humid environment, roots can simply boil. Therefore, it is best to replenish the liquid in the plants in the evening, when the heat peaks.
