How to Repot a Cactus
Article Summary: This article covers related contents about how to repot a cactus, including the timing and methods for repotting a cactus, with specific introductions as follows:
The cactus is a drought-resistant and heat-tolerant plant that is very easy to cultivate. It has certain radiation protection functions and can also purify the air. It is best to keep it in the living room. During the cultivation process, the cactus needs to be repotted. It is usually chosen to repot in spring and autumn because these two seasons are the growing periods of the cactus, and repotting can help it recover growth quickly, which does not have a significant impact on its growth. Repotting is needed every 1-2 years to ensure it gets enough nutrients for growth.
1. Repotting Time
The best time to repot a cactus is in spring and autumn. The temperatures during these seasons are suitable, which are the growing periods of the cactus. After repotting, it can recover growth quickly. It is recommended to repot every 1-2 years to ensure the soil is loose and fertile, meeting its nutritional needs for growth.
2. Root Treatment
Before repotting a cactus, you need to check its root growth. If root rot occurs, it is necessary to trim it promptly. As a drought-resistant plant, the cactus does not need to be watered before repotting, allowing the potting soil to remain dry to facilitate repotting. This avoids the impact of repotting on the cactus roots.
3. Preparing for Repotting
Choose a terracotta pot of the same size as the cactus plant for repotting, as terracotta pots have good breathability, which is beneficial for root growth. Gloves need to be prepared before repotting to avoid injury from the spines on the plant. Use a mixture of珍珠岩 (perlite), peat soil, and vermiculite in a ratio of 3:5:2 to ensure the soil has enough nutrients.
4. Repotting
Keep the potting soil of the cactus dry, tap the sides of the pot gently a few times, and remove the whole plant from the soil. The roots can be left with some soil. Clean all the rotting roots of the cactus and then place it directly into the prepared new potting soil, followed by filling in the soil that has been mixed.
The above sharing on how to repot a cactus and the specific introduction of the timing and methods for repotting a cactus are hoped to bring some knowledge of flowers to green plant enthusiasts.
