1. How to treat black spots on the leaves of trumpet creeper

1. Pruning and spraying: The black spots on its leaves are likely caused by improper maintenance and infection with bacteria. If you want to treat it, it is recommended to directly cut off the leaves with black spots to prevent the further spread of the bacteria. After pruning, you should spray special fungicide so that the tree may slowly recover its health.

2. Reduce watering: Although it likes a moist growing environment, water cannot accumulate. If you water too much, the roots will easily rot, the disease resistance will decrease, and black spots will appear on the leaves. Watering should be reduced and ventilation should be increased.

3. Apply fertilizer in appropriate amounts: The black spots on its leaves are most likely caused by improper fertilization. A lot of nutrients are consumed during the growth period, so it is necessary to apply thin fertilizers frequently to supplement the nutrients. But be careful not to use too high a concentration of fertilizer, and do not use raw fertilizer, as this can easily cause fertilizer damage, which will lead to black spots on the leaves.

2. What should I do if the leaves of trumpet creeper fall off when touched?

If the leaves of trumpet creeper fall off when touched, it is probably because of overwatering and root rot. After the roots rot, the plant cannot provide water and nutrients normally, so the leaves fall off easily when touched. To reduce watering, there must be no accumulation of water. It may also be due to improper fertilization, where the concentration of fertilizer applied is too high and burns the roots. It is recommended to remove the plant from the pot as soon as possible, trim off the rotten roots, and replant it after disinfection.
