Reason: if there is no scientific regulation and control of watering when raising the Dragon whisker tree, water again before the flower soil is dried up, so that there is water in the soil. Then its roots will be waterlogged and rotted, and the affected roots will absorb water and nutrients from the soil. Its leaves will also be due to the lack of necessary water and nutrients, resulting in yellow and dry problems.
Treatment method: loosen the soil and take the plant out of the basin. Then check its root system and cut off the rotten and blackened parts. Then plant it in a new flower soil, and reduce the number of watering
Reason: if it is usually raised in a place with too much light, its leaves will be scorched by strong light for a long time, resulting in water shortage and the problem of dry and yellow hair.
Treatment: first, cut off the leaves that have been severely sunburned, then put the plants in the half shade, water them properly, and wait for them to recover.
Cause: if the leaves of the plant are eaten by some pests, its normal physiological activities will be hindered, resulting in the problem of yellowing and drying.
Treatment: move the plant to a well ventilated place, then spray some liquid medicine to kill the pests.
