Why do bougainvillea leaves fall off when touched?

1. Causes

1. It may be caused by water. Too much water will make the spider's frontal roots unable to breathe, causing the plant to dry up and the leaves to wilt. Too little water can also cause this situation. Therefore, the water should be replenished only when the soil is dry and not watered again unless the soil is dry.

2. Give it plenty of light. Long-term absence of sunlight will cause the leaves of the plant to fall off at the slightest touch, or even cause it to grow too tall. Therefore, it should be placed in a sunny place for maintenance and avoid strong sunlight.

3. Fertilizer should be used appropriately, neither too much nor too little. You only need to apply more fertilizer during its growing season, and reduce the amount of fertilizer in other seasons. And the concentration of fertilizer should not be too high. It is better to apply dilute fertilizer. Fertilization is usually done once every 10 days.

4. Another possibility is that it is caused by the invasion of diseases, so we need to observe it in time. If the disease is found, it is advisable to spray the pesticide immediately for prevention and control, and trim the necrotic leaves in time.
