What to do if all the leaves of bougainvillea fall off in winter

1. Treatment methods

1. First, cut off some dry young branches. If the frostbitten branches are not cut off, the nutrients will be consumed. Use chopsticks to slowly dig up the soil in the pot and check for root damage. If most of the roots are black, you need to trim the roots and change the pot; if most of the roots are white, you do not need to change the pot.

2. If you need to repot, you need to let the seedlings grow slowly first. Don't water them too much. Just pour some water along the edge of the pot. If you don't need to repot, you need to add a layer of soil to keep it warm. It is best to place it in a place with a temperature of 16-25℃.

3. The last step is to promote the germination of new shoots on the plants. Germination requires humidity, temperature and nutrients. You need to spray the plants with some thin fertilizer, ensure that the temperature is not too low, the humidity is not too high, and there is proper ventilation.

2. Precautions

Winter is a very cold season. If you want bougainvillea to survive the winter smoothly, you must find a relatively warm environment to grow it. You cannot grow it outdoors. If the temperature is too low, the plants will be frozen and cause leaf fall, so it must be taken seriously.
