The reason why the leaves of bougainvillea fall off when touched and the solution

1. Reasons

1. Improper watering: Bougainvillea needs to be watered properly during maintenance. If it is not watered for a long time, the soil will be very dry, which will affect its growth, and the leaves will turn yellow and fall off at the touch. Too much watering can also cause this problem. The accumulated water can cause root rot, and the inability to transport water and nutrients normally can also cause the leaves to wilt and fall off.

2. Lack of sunlight: Bougainvillea has a great demand for light. If it is kept in a place with poor light for a long time, it will be too dark and the branches will become weak, and the leaves will turn yellow and wither and fall off.

3. Pests and diseases: Improper maintenance may lead to pests and diseases, which may also cause this situation.

4. Too much fertilizer: Although it needs nutrients, too much fertilizer is not conducive to its growth. Instead, it will cause root burn and cause the leaves to turn yellow and fall off.

2. Solution

1. Reasonable watering: Pay attention to correct watering during maintenance, and water in time during the growth period, but not too much. If you water too much, place it in a well-ventilated place to promote evaporation.

2. Supplement sunlight: Bougainvillea should not be deprived of sunlight. It should be kept in a well-lit place and exposed to sufficient sunlight during the growing period.

3. Prevention and control of pests and diseases: Pay attention to ventilation and strengthen the prevention and control of pests and diseases. After discovery, cut off the diseased and insect-infested leaves and then spray pesticides.

4. Dilution by watering: During maintenance, fertilizer should be applied according to the growth. If fertilizer damage occurs, water should be applied immediately to dilute the fertilizer in the pot.
