Cactus Repotting Season
Comprehensive analysis of the experience in cactus care, specifically focusing on the repotting season for cacti. The details are as follows:
Speaking of the cactus repotting season, it is most suitable after the dormancy period and before entering the growing phase, which is approximately the early spring. Of course, autumn is also a good time for repotting.
Cacti are generally repotted once every one to two years. This is because after a year or two of growth, the nutrients in the pot have been depleted, the soil becomes acidic and compacted, which affects the root growth of the cactus and its absorption of nutrients from the soil. Repotting by adding fresh soil, pruning the roots, provides a more suitable growing space for the cactus, promoting root development. This measure is essential and a fundamental technique for successfully caring for cacti.
The cactus in the illustration is not suitable for repotting as it already has flower buds.
The specific method of repotting is simple:
1. Stop watering one week before repotting to allow the soil to completely dry. Before repotting, wear thick gloves to avoid being pricked by the cactus spines.
2. Tap the pot wall to loosen the soil from the pot wall, which helps in removing the whole cactus from the pot.
3. Clean the old soil.
4. For robust varieties, you can slightly prune the roots, but for sensitive-rooted varieties, this step can be omitted.
5. Place the plant at an appropriate height and then pour in the potting soil, noting that cacti should be planted shallowly.
6. Lightly compact the potting soil, be careful not to make it too tight to avoid affecting drainage.
7. Place the newly repotted cactus in a bright and well-ventilated area. Do not water at this time because the cactus roots are damaged after pruning, and the cactus needs to adapt to the new soil. Immediate watering often causes root rot and other problems. Therefore, it must be set aside for a period, usually 8 to 14 days. When the top of the cactus begins to sprout or grow new spines, it means the new roots have grown, and the cactus can be watered, indicating the success of repotting. After a few days, you can water normally and gradually increase sunlight, transitioning to daily care.
