The vast majority of cacti, like many other indoor plants, have a dormant period in winter. For better cactus growth, especially for flowering species, it is necessary to give rest in the winter. Therefore, the task of caring for them is to prevent growth in winter, since during winter they stretch out and lose their normal appearance. In winter, cacti can be kept on window sills. To prevent their roots from cooling, the pots are placed on a stand. Cacti can be placed on a hill 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), leaf-like cactus (phyllocactus) and others blooming in spring.
In winter, during dormancy, 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 invisible cracks and wounds on the stem, which makes it rot. The room temperature should be 10-14 ° heat.
When spring comes, 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 by a board, but it is better to put them in a box filled with peat or earth. You can take out boxes with plants on the balcony. Larger specimens are useful to plant from pots in the ground in the garden, preferably on a stone slide. In mid-August, they are again transplanted into pots so that they take root before winter. They are planted in the same land in which they grew in the summer, but sand is added. In autumn, when the temperature drops to 6-8 ° at night, all cacti are transferred from the garden and balcony to the rooms.
Watering cacti depends on the time of year, pot size, plant age, room temperature. In spring and summer, during the growth of cacti, they should be watered daily. The more cacti grow in large pots or tubs, the more rare they need to be watered. Old cacti are watered less often, since they have large water supplies. Especially plentiful watering they require in the summer during growth. They are watered in the evening. The lower the temperature, the less they evaporate water and the less watering is required. In autumn, watering is gradually reduced, and in winter it is very rarely watered. If cacti are often watered in winter, they do not go through a dormant period, are 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 cease to be watered so that the earth is easier to fall behind the roots. Plants are wrapped in strips of thick paper or straps (Fig. 1) and knocked out of the pot. An earthen lump can be pushed with a stick through a hole in the bottom of an inverted pot. Dead and rotten roots are cut to living tissue. Sprinkle all sections with carbon powder.
Cacti are transplanted in the same way as indoor flowers. The plant must be planted in the center of the pot. If it is tilted or curved, you should put a peg and tie a cactus to it to straighten. You can not fill the ground with the stem, especially its green part, as it can rot. Most transplant cacti are sprinkled with sand at the root neck. Young plants are replanted annually, and three to four year olds can be replanted in one to two years.
All cacti blooming in early spring require transplantation immediately after flowering. After transplanting, they are not watered for two to three days.
