All cacti prefer soft water that does not contain chlorine. The water must be clean, i.e. do not contain any impurities or salts. Ideally, you would need to use rainwater or thawed water, but you need to have patience to collect it, so you can use water that has been separated for at least a day or boiled water, you can also use water filtered with household water filters. The water temperature for irrigation should always be equal to room temperature or slightly higher.

Regarding the method of watering cacti - from above or through a pallet, sometimes there is a lot of controversy among cactusists. Apparently, this is due to the fact that in cacti, the main part of the roots that absorb water is located in the lower part of the root system. Undoubtedly, each method has its own advantages:

Watering from above is convenient and familiar, you can see how much water is consumed, the entire earthy clod is moistened with water, but after a while, with this method of watering, nutrients are washed out from the upper layers of the soil. In order not to wet the stalk of the cactus, it is convenient to make a watering pad from a usually plastic bottle: take a piece of flexible tube (for example, from a dropper) or a juice tube, use a drill or an awl to make a hole of a suitable diameter in the lid and insert the tube.

Watering through a pan is convenient because the soil in the pot is not washed out, soil nutrients are washed out much longer than when watering from above, but with this method of watering, it is difficult to know how much water the plant needs, i.e. this method is more suitable for an experienced cactusist. For some reason, the question of the method of watering is very exciting for the owners of cacti, although in fact this is not fundamentally important, but rather a matter of taste and experience.

How to water cacti

  • do not allow water to fall on the stalk of the cactus during watering, pour it onto the ground from the edges of the pot;
  • stagnation of water in the pot should not be allowed, for this each cactus must be provided with good drainage, and when watering from the pan, after a while (after the roots have absorbed the water), the remaining water is drained;
  • any cactus can endure a certain time in completely dry soil, even during the period of growth and flowering, while excess water can be fatal for it;
  • the amount and frequency of watering directly depend on the temperature and humidity of the ambient air, the lower the temperature and higher the air humidity, the slower the evaporation of water from the substrate, the less often you need to water. In addition, the temperature affects the rate of absorption of water from the soil by the roots. Cold water is practically not absorbed by the roots. But pay attention, if for us cold water is 18-19 ° С, then for cacti it is still warm, and cold water from 12 and below. The cooler the ambient temperature, the less moisture the cactus needs. When there are hot, dry days in summer, cacti are watered every day, on a cool and even more rainy day, it is better not to water the cactus;
  • the time for watering cacti is morning or evening, it is believed that it is necessary to water cacti in the evening in the summer, and at other times of the year in the morning, but this, again, is not of fundamental importance.

When to water more or less cacti

Almost all cacti prefer cold (or at least cool) wintering, but not every owner can provide this, and then cacti hibernate at normal room temperature, which can be 18-25 ° C. With such a warm wintering, cacti are watered less often than in summer (at the same temperature), the earth should have time to dry out well.

Water more

Water less
  • Cacti belonging to the moisture-loving genus (eg, ripsalis, zygocactus)
  • Growing cacti
  • Cacti with a well-developed large root system
  • Cacti growing in a porous container, such as a clay pot
  • Cacti growing in loose soil with a high proportion of sand and brick chips
  • Cacti in a high temperature room
  • Cacti in a dry room, especially with central heating
  • Dry loving cacti (all desert cacti such as mammillaria)
  • Dormant cacti
  • Cacti with weak or damaged roots
  • Cacti grown in non-porous containers such as plastic
  • Cacti growing in denser clay soil
  • Cacti in a low temperature room
  • Low humidity indoors, such as a cactus standing by an open window on a rainy day

In most cacti, flowering is not associated with the growth period, i.e. and in winter during the dormant period, cacti can bloom. Since watering is sharply reduced during the dormant period, the question often arises of how to water cacti blooming in winter. In this case, watering should be a little more or more often than if the plants were not blooming, but you definitely need to water much less often than in spring and summer.

Very often, when watering with hard water containing a lot of lime, light brown raids form on the stem of the cactus at the base, which eventually turn into crusty growths and are not removed. Most often this happens in cacti that do not have thorns or with small, sparse thorns. It is not uncommon for this phenomenon to be mistaken for a disease, but it is salt deposits from the water, which are eaten into the tissues of the cactus. Therefore, it is recommended to water the cacti with boiled or filtered water.

Air humidity

It is known that all cacti tolerate dry air well and therefore are considered hardy plants, but in nature most of them are refreshed with dew or fog in the morning and evening. Cacti are very responsive to daily spraying during their natural hours, but in order not to harm the plants, it is necessary to spray only from a very fine - dusty spray, so that no jets of water descend along the cactus trunk.

The spray water temperature should be slightly above room temperature, i.e. warm (30-40 ° C). On sunny days, spraying is carried out only when the sun's rays have or have not yet hit the plant. It is better to stop spraying with the onset of rainy autumn days, but in winter you can spray cacti at the end of a sunny day. Read more about wintering cacti. Cacti with leaves (Ripsalis, Epiphyllum, etc.) can not only be sprayed, but also given a shower to wash away the dust and prevent the appearance of spider mites.
