How to repot and transplant a cactusIntroduction: This article provides information on how to repot and transplant a cactus and the best timing for repotting, with detailed explanations below.Nowadays, more and more people are fond of growing cacti because they bloom beautifully and are not very expensive. However, many people encounter root rot after purchasing them and placing them in their homes, mainly due to improper handling when potting them. This is also the case when repotting a cactus, which can lead to the plant dying. Therefore, to grow them successfully, it is essential to master the "tricks" of repotting and potting, as large and small cacti are different. Learning to pot them can promote rapid root growth and prevent rotting or waterlogging.1. SeedlingsMany people like to sow cacti themselves. When sowing cacti, it is important to remember that the plant should grow for more than half a year before transplanting. If the ball is less than 0.5 millimeters in diameter, it is very small, and the survival rate of transplanting 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 root systems are delicate and weak. Do not plant them directly after removing them from the soil, as their roots may rot, causing the entire ball to wither and die.Do not leave them to dry for too long. After removing the ball from the soil, trim the fine roots and appropriately shorten the long main roots, then place it in a shaded and well-ventilated area for two to three days. Since their roots are delicate, two to three days are sufficient for the root wounds to heal.After drying, plant them in soil with half颗粒, not too large, water thoroughly after planting, and place them in a shaded and well-ventilated position. They will quickly grow new roots. If a small ball is left to dry for two weeks, it will become shriveled, and even if planted, it will struggle to grow new roots. Therefore, it is important to remember that this method should be used for balls with a diameter of 1.5 centimeters or less.2. Large ballsUsually, when people buy cacti, they purchase large ones, with diameters of two centimeters or more. For these large balls, when you want to pot or repot them, do not buy those that come with roots and pots, as the roots are accustomed to the original environment. Watering them in an unsuitable environment can easily cause root rot and the entire ball may wither. Remove all the soil and expose the rootlets. The first step is to cut off all the fine roots, leaving only the thicker ones, which should be shortened to about two centimeters.After pruning, do not rush to pot. Place it in a sunny and well-ventilated area to dry for at least one week. The purpose of drying is to allow the wounds to dry and heal completely. When the ball is dry, it will not appear significantly weak. Choose a pot that is one to two centimeters larger than the diameter of the ball, not deep, and use soil with 50-70%颗粒. Plant it directly, water thoroughly, and place it in direct sunlight. It will quickly grow new roots. If planted directly, it is prone to black rot and waterlogging. It is essential to trim the roots and dry them for more than one week, even if the diameter of the ball is between 1.5 and 2 centimeters.3. Sideshoots without rootsMany people choose to buy two to three-centimeter side shoots when large cacti are expensive. These side shoots do not have roots. How should we plant them? For these side shoots, after purchasing them, place them in a sunny and well-ventilated area to dry for at least one week. The ball should be more than two centimeters in diameter, and it will not shrivel during drying. Roots may grow from the bottom during this time.The purpose of drying is to allow the bottom wounds to heal, as side shoots are connected to the mother ball by a vascular bundle. When cut, a large wound is inevitable. After the wound is dry, find a suitable pot and use soil with half颗粒, water thoroughly, and plant the ball with about 0.5 centimeters of soil covering it. Ensure adequate sunlight and good ventilation. When the topsoil is dry to a depth of one centimeter, water it promptly. It will grow roots quickly.Repotting a cactus does not require special skills; the only thing to do is to dry the roots. If this step is skipped, the plant will have to heal the root wounds in the soil, and any improper handling can lead to infection from moisture or fungi in the soil, causing the entire ball to rot. It is important not to be afraid to dry the roots; after proper drying, the survival rate can reach over 90%.Have you understood the detailed information on how to repot and transplant a cactus and the best timing for repotting provided above?
