What should I do if the leaves of Bougainvillea fall off due to excessive fertilization? The reasons and solutions for the leaves turning yellow and falling off when touched

1. What to do if excessive fertilization causes leaf drop

1. Applying too much fertilizer on a regular basis will cause root burn and leaf fall. If the situation is not serious, you can give it plenty of water to dilute the fertilizer in the soil. Also, do not fertilize it in a short period of time, and it will recover slowly.

2. If a lot of leaves fall off, it means that the root burn is quite serious. First, remove the bougainvillea from the pot, rinse off the soil above the roots, and use scissors to cut off the burnt roots. It is best to replace the original soil in the pot, or soak it in water and let the roots dry. Finally, plant the plant and wait for it to settle into the pot.

2. Causes and solutions for yellow leaves that fall off at the touch

1. Too much water: When watering the plants, if the amount of water is not controlled well, resulting in excessive water in the soil, this situation will occur. Pay attention to water control in a short period of time and drain excess water in the soil in time. Water again after the soil is dry in the later stage.

2. Lack of light: It likes sunlight. If there is insufficient light for a long time, the plant will not only grow very weak, but also have yellow leaves and fall off. It should be moved to a sunny place and given sufficient light during its growth period.

3. Diseases: When the maintenance environment is poorly ventilated, the plants will be infected with diseases, the most common of which are brown spot disease and leaf spot disease. After the disease occurs, the leaves of the plant will turn yellow and will easily fall off later. Ventilation should be increased, diluted pesticides should be used for spraying, and the diseased leaves should be cut off.
