What are the reasons for the abscission of christmas cactus and orchid

The normal growth of the plant is likely to be affected when the sun is not abundant. When the temperature is high and the light is strong, the flower bud may fall off when the plant is exposed to sunlight. At the flowering stage, there is little water demand, so we can make the soil slightly wetter. The lack of nutrients absorbed by plants before flowering is also an important reason.

I. light

1. The plants need to receive sufficient light during the flowering period. When the sun is not enough, there is a great possibility of falling buds.

2. In the season with high temperature and strong light, the flower bud may fall off when the plant is exposed to sunlight.

3. If the position of the plant is often moved, it will also affect the growth of the flower bud, so avoid changing the position.

Water content

The water requirement of plants is different in different seasons and different temperatures. At the flowering stage, the plant does not need to be watered too much. At this time, it only needs to keep the soil slightly moist.

Fertilizer

If the plant absorbs insufficient nutrients before flowering. Or the plants do not supplement nutrients in time after flowering. In that case, it is likely that the flower bud will fall off.

Temperature

If the temperature is too low, or the temperature drops suddenly, it may also cause the flower bud to fall off. The suitable temperature for plant growth is about 20 ℃.
