The vast majority of cacti, like many other indoor plants, have a dormant period in winter. For better growth of cacti, especially for flowering species, it is necessary to give rest during the winter. Therefore, the task of caring for them is to prevent growth in winter, since during the winter they stretch out and lose their normal appearance. In winter, cacti can be kept on windowsills. To prevent their roots from cooling, the pots are placed on a stand. Cacti can be placed on the slide in front of the window and on the side shelves arranged on the sides of the window opening. The brightest places require a hedgehog cactus (echinocereus), a leaf-like cactus (phyllocactus) and others that bloom in spring.
In winter, during the dormant period, watering is given once every 7-10 days. It is better to take warm water, 2-3 ° higher than the room temperature.
When watering, make sure that water does not fall on the cactus stem, especially in winter. Water can penetrate into inconspicuous cracks and wounds on the stem, causing it to rot. The room temperature should be 10-14 ° C.
When spring comes, the plants are watered more often and sprayed once or twice a month. They are protected from sunburn by shading.

In the summer, from heating, the pots are shaded with a board, but it is better to put them in a box filled with peat or earth. You can take boxes with plants to the balcony. It is useful to plant larger specimens from pots into the ground in the garden, preferably on stone slides. In mid-August, they are again transplanted into pots so that they take root before winter. They are planted in the very ground in which they grew in summer, but sand is added. In autumn, when the temperature at night drops to 6-8 °, all cacti are transferred from the garden and balcony to the rooms.
Watering cacti depends on the season, the size of the pot, the age of the plants, the temperature of the rooms. In spring and summer, when cacti are growing, they should be watered daily. The larger cacti grow in pots or tubs, the more rarely they need watering. Older cacti are less watered as they have a large supply of water. They require especially abundant watering in summer during growth. They are watered in the evening. The lower the temperature, the less they evaporate water and the less watering is required. Watering is gradually reduced in autumn, and very rarely in winter. If cacti are watered frequently in winter, they do not go through a dormant period, become depleted and do not form flowers.
Cacti are transplanted in the spring when they begin to grow. This happens in April and early May. Two or three days before transplanting, they stop watering them so that the earth more easily lags behind the roots. Plants are wrapped in strips of thick paper or straps (Fig. 1) and knocked out of the pot. The earth ball can be pushed with a stick through the hole in the bottom of an inverted pot. Dead and rotten roots are cut to living tissue. All sections are sprinkled with charcoal powder.
Cacti are transplanted in the same way as indoor flowers. The plant needs to be planted in the center of the pot. If it is tilted or bent, you should put a peg and tie the cactus to it to straighten. Do not cover the stem with earth, especially its green part, as it can rot. Most of the cacti are sprinkled with sand at the root collar during transplantation. Young plants are replanted annually, while three to four year olds can be replanted after one to two years.
All cacti blooming in early spring require replanting immediately after flowering. After transplanting, they are not watered for two or three days.
