Lagerstroemia indica stem black

The black and yellow leaves of happiness trees are usually caused by environmental problems or improper maintenance. Here are some possible first aid measures:

Check whether the soil is too wet or too dry. If the soil is too wet, you can reduce the amount of water and let the soil dry properly. If the soil is too dry, you can increase the amount of water appropriately to keep the soil moist.

Make sure there is enough light. Happiness trees need bright light, but excessive exposure can also make their leaves yellow. If the light is insufficient, you can move the plants to a better place.

Fertilize. The yellowing of leaves may be caused by lack of nutrition. Fertilizers suitable for happiness trees can be used and fertilized appropriately according to the instructions.

Check whether there are pests and diseases, such as eggs, aphids, mites, etc. If pests and diseases are found, corresponding pesticides can be used for treatment.

After emergency treatment, it is necessary to continuously observe the state of the happiness tree and take timely measures to ensure its health. In addition, be careful not to over-water or over-fertilize, so as not to cause more serious damage.
