Cacti mostly are unpretentious plants therefore comfortably feel practically in any conditions. And if conditions of keeping are pleasant to them, many of them are inclined to expand quickly enough.
Instruction
1. Health indicators at cacti a bit differents, than at all other plants. First of all indicator of health is the quantity of prickles and blossoming of cactus, and only after that - growth. Therefore if the big cactus sits in close pot, but blossoms and does not lose the needles, you should not replace it so far, he very comfortably feels. Lime application of the soil from which other plants, to cacti only on advantage as they grow on limy soils in the nature suffer. If the small cactus to the detriment of all the rest grows in length, it demonstrates that living conditions do not suit it, it will be very difficult for such cactus to winter. In this case can change as most often the reason of underdevelopment of needles and lack of blossoming in improper soil which needs to be replaced is required. Now it is possible to buy ready substrate for cacti and succulents or to find all necessary components separately and to make soil independently.
2. For pot with cactus openings in day and layer of drainage for which it is possible to use haydite or small pebble are obligatory. These plants do not need stagnation of water in pot therefore it is necessary to avoid gulfs in every way. The pot for the big cactus needing change is chosen slightly more previous and the same form. It is convenient to determine the suitable size of new capacity, combining it with old. In case old can be located completely in new, and between walls there will be gap of 1-2 cm, it is the suitable diameter of capacity for cactus. To take out old cactus from pot, without having damaged its needles and the hands, it is not enough to use working gloves. Coiling of cactus newspapers or brown paper too not the best option as big and strong needles will tear this paper with ease, and small needles can be damaged. Most it is possible to tell also concerning coiling of cacti for change by fabric. It is the best of all to use for these purposes foam rubber of sufficient thickness or packing film with air chambers. Needles will enter these materials with ease, but will not tear them and will not break.
3. When the plant is taken out from pot, it is necessary to examine carefully its roots and to remove dry or rotten when finding those. If on roots wreckers are found, it is necessary to process them the corresponding chemical medicines. The majority of cacti do not love excessive scope in pot and therefore if at extraction of plant it has turned out that to its roots even the old pot is big, it is necessary to choose suitable by the size. Roots when landing it is optional ideal to straighten and give them natural look. Key indicator - that tips of roots have been directed down, but not inside or sideways. Still roots need to set the direction inside as they grow in the nature if to direct roots outside, they will not grow and will die off. It is impossible to bury root neck of cactus more, than before, but also it is excessive to open it is not necessary. After the cactus has taken the place in the center of pot, the pot is placed on the constant place. For week it is necessary to leave this cactus for adaptation during season of active growth, after that - to water. If change was carried out in the winter, in the early spring or late fall, during wintering, the cactus is not watered till spring.
