How to Repot a Cactus
In detail for the concerned netizens, explaining how to repot a cactus and the timing and methods of cactus repotting in terms of plant knowledge. Let's take a look together below.
Cacti are drought-resistant and heat-tolerant plants that are very easy to cultivate. They have certain radiation protection functions and can purify the air. It's best to keep them in the living room. During the cultivation process, it is necessary to repot the cactus. Usually, repotting is chosen in spring and autumn because these two seasons are the growing periods of the cactus, and repotting can help it recover and grow quickly, with minimal impact on its growth. Repotting is needed every 1-2 years to ensure sufficient nutrients for its growth.
1. Repotting Time
The time for repotting a cactus is in spring and autumn, when the temperature is suitable and the plant is in its growing period. After repotting, it can recover and grow quickly. It is best to repot every 1-2 years to ensure that the soil is loose and fertile, meeting its nutrient requirements for growth.
2. Root Treatment
Before repotting a cactus, it is necessary to inspect the condition of its roots. If there is rot, it should be pruned promptly. Cacti are drought-resistant plants, and there is no need to water them before repotting, allowing the potting soil to be dry to make repotting easier. This avoids any impact on the cactus roots during repotting.
3. Preparing for Repotting
Choose a clay pot of the same size as the plant for repotting the cactus. Clay pots have good breathability, which is beneficial for the growth of the roots. Gloves should be prepared before repotting to avoid injury from the spines on the plant. Mix珍珠岩 (perlite), 草炭土 (peat soil), and 蛭石 (vermiculite) in a ratio of 3:5:2 to ensure sufficient soil nutrients.
4. Repotting
Keep the potting soil of the cactus dry, tap it gently around, remove the entire plant from the potting soil, and allow the roots to retain some soil. Clean all the rotting roots of the cactus, and after processing, place it directly in the prepared new potting soil and then fill it with the mixed soil.
