1. PruningWhen the roots of the dragon beard tree rot, you need to take it out of the flowerpot and put it in clean water to wash off the soil on it. Then prepare a pair of sterilized scissors and cut off those roots that have rotted and turned black. Then cut off most of the leaves above the plant. This can reduce nutrient consumption and help it grow new roots. 2. Chemical treatmentPrepare some disinfectant and dilute it with water. Then put the roots of the plants in it and soak for about 20-30 minutes. Then take it out, dry it, put it in rooting water diluted a thousand times, soak it for about 5 hours, take it out, and dry it. 3. Prepare new soilBecause the reason for its root rot may be that the old soil contains a large amount of pathogens or stagnant water, it is best to replant it with new soil so that its roots will not rot again due to these reasons. It is recommended to choose new soil with good air permeability and high drainage capacity. It can be made by mixing five parts of garden soil, three parts of leaf mold and one part of river sand. 4. ReplantingSterilize the new soil and put it into the flowerpot. Then dig a small hole on it, plant the plant in it, and fill the hole with surrounding soil. Then put it in a place with soft light, control watering, and wait for it to recover slowly. |
