The solution to the problem of bougainvillea flower falling

1. Supplementary lighting

It is a sun-loving plant. If it is placed in a shady environment for a long time, not only will the flowers fall off, but the leaves will also fall off. In this case, you need to place it where the sun can shine. After being exposed to the sun for a period of time, it will return to normal on its own. However, this cannot be done in summer. It needs proper shade and exposure to scattered light.

2. Control water application

Adding water is very important for growth. If you add too much water without considering the growth needs, water may accumulate in the pot, the roots will rot, and the flowers and leaves above will fall off. From the period before flowering, you should control the amount of water you apply and avoid applying too much water.

3. Balanced fertilization

Incorrect proportion and amount of fertilizer is also one of the reasons. When too much fertilizer causes fertilizer damage, or too much nitrogen fertilizer causes the plant to grow too tall, the flowers will fall off. The proportion of nutrients applied should be controlled. Do not apply too much nitrogen fertilizer. You can apply some phosphorus fertilizer in the early stage of flowering, which will help flowering.

4. Control temperature

A drop in temperature can also cause it to fall off. The best growth temperature is 20-30℃. Observe the weather conditions in winter and move it indoors as soon as possible.
