How to transplant a cactus: Tips for repotting and caring for a cactus.

How to transplant a cactusToday's focus is on introducing you to the experience of how to transplant a cactus and the small green plant maintenance tips for changing pots. Next, let me give you a detailed answer.Nowadays, more and more people are fond of growing cacti because they have very beautiful flowers and are not very expensive. However, most people who buy them and place them at home are prone to root rot, mainly due to improper operations when potting the cactus. The same is true when changing pots for a cactus, which often leads to death. Therefore, if we want to grow them well, we must master the "tricks" of potting and repotting. Large and small cacti are different, and learning to pot them can help them grow roots quickly without rotting or becoming watery.1. SeedlingsMany people like to sow cacti themselves. When sowing cacti, remember that the ball must grow for more than half a year before it can be transplanted. If the ball is less than 0.5 millimeters in diameter, it is very small, and the survival rate of transplanting at this time is very low. It is best to wait until the ball is about one centimeter in diameter before transplanting. When transplanting seedlings, remember that their roots are relatively thin and weak, so we should not plant them directly, as the roots may rot and cause the entire ball to die.Do not expose them to the sun for too long. After taking the ball out of the soil, trim the fine roots and shorten the long main roots appropriately, then place them in a place with scattered light and good ventilation to dry for two to three days. Since their roots are relatively thin, two to three days is enough for the root wounds to heal.After drying, plant them in soil with half particles, not too large in size. After planting, water thoroughly and place them in a position with scattered light and good ventilation, and they will quickly grow new roots. If a small ball is left to dry for two weeks, it will shrink, and even if planted, it will be difficult to grow new roots. Therefore, it is important to remember that all cacti with a diameter of 1.5 centimeters or less should be handled this way.How to transplant a cactus2. Large ballsUsually, when we buy cacti, we buy the large ones, with diameters of over two centimeters. For these large balls, when we want to pot or repot them, we should never buy those that come with roots and pots, as they may not be suitable for your environment. The roots are grown in the original environment, and if watered, they can easily rot and cause the entire ball to become watery. We need to remove all the soil and expose the rootlets, first trimming all the fine roots, leaving only the thicker ones, and then shortening the thicker roots to about two centimeters.After trimming, do not rush to pot. Place them in a well-lit and ventilated area to dry for at least one week. The purpose of drying is to allow the wounds to dry out and heal completely. After drying, the ball should not appear significantly weakened. Then, choose a pot that is one to two centimeters larger than the outside diameter of the entire ball, not deep, and use soil with 50 to 70% particles. Plant directly, water thoroughly, and place them in the sunlight, and they will quickly grow new roots. If you plant them directly, they are likely to become black and watery. Make sure to trim the roots and dry for more than a week, even for balls with diameters of 1.5 to 2 centimeters.3. Side buds without rootsMany people buy side buds, which are about two to three centimeters in diameter, as they are cheaper than large balls. These side buds have no roots. How should we plant them? For these side buds, after purchasing, place them in a well-lit and ventilated area to dry for at least one week. The ball should be over two centimeters in diameter and will not shrink during the drying process. In fact, roots may grow from the bottom during the drying period.
