How to give first aid to rotten duck palm wood

After it is found that it has rotten roots, it needs to be separated from the flowerpot without damaging the main roots. Shake off the soil nearby, wash it in water, cut off the rotten roots, and properly trim the branches and leaves. After trimming, soak the wound in carbendazim or potassium permanganate, soak it for half an hour, take it out and dry it, and wait for the basin. Prepare new flower pots and soil, disinfect them before use, and then plant duck palm wood in it and put it in a cool place to wait for recovery.
