1. Cut off rotten rootsWhen you find root rot, immediately remove the plant from the potting soil and cut off the rotten part with sterilized scissors. If it is only minor, you can carefully scrape off the rotten part. In short, the rotten parts must be cut off, otherwise it will continue to deteriorate, causing the entire plant to rot and eventually die beyond repair. 2. Soaking and disinfectionIt cannot be planted immediately after cutting. It must be disinfected first, otherwise it is easy to retain bacteria and continue to infect. When disinfecting, you can dilute the potassium permanganate solution, then put the trimmed roots in it and soak them for about two hours. 3. Change the soil and potWhen potting, you need to prepare new potting soil. Remember not to reuse the original soil because there will be residual germs, which can avoid infection. After preparing the new soil, it is best to soak it with disinfectant. The soaked soil can promote the later absorption of the tree trunk, but the amount should not be too much to avoid burning the seedlings. |
