Can the old cactus be potted directly?
If the old cactus is newly purchased, it is best to process it before potting. Below, we will take a detailed look at the potting process of the old cactus.
Whether the old cactus can be potted directly: Pruning
Usually, the old cactus we buy is in the form of bare roots, and the roots have basically been repaired by the seller. We just need to check if there are any withered roots. If it is a potted cactus, it is best to carefully inspect the roots and then prune the problematic roots to ensure the cactus can grow healthier in the future.
Disinfection
After pruning the roots of the old cactus, do not pot it directly because the roots of the old cactus have many wounds, which are easily infected and rot when exposed to water. Therefore, we need to disinfect the roots, and some cactus roots may also carry eggs and germs, which are difficult to detect with the naked eye. Disinfection can eliminate them effectively.
Drying
After disinfection, we need to place the old cactus in a well-ventilated area without direct sunlight to dry until the root wounds are completely dry. Note that the drying temperature should be kept around 20 degrees.
Potting
After all the above work is done, we can pot the old cactus. The soil used for potting must have good drainage. If we can't mix it well, we can buy ready-made soil online. Then water the cactus slightly and place it in a shady and well-ventilated area to wait for it to settle in.
The above is a detailed explanation of whether the old cactus can be potted directly, for everyone's reference and suggestions!
