Flowers and plants should be provided with appropriate light when they are maintained. If they are placed in a place with strong light for a long time, they will burn their leaves and turn yellow. But if it is kept away from light, the leaves will be soft, wilting and yellow. So it's best to put it in a bright and scattered place, so that it's not sunburnt
The main reason why the leaves turn yellow during maintenance is improper watering, water shortage or ponding. The old leaves are yellow first, from top to bottom, while the young leaves are yellow first, and the new shoots shrink. If you are short of water, make up the water in time, stop the water, put it in a well ventilated place, let the water evaporate as soon as possible.
The yellow leaves of flowers and plants may also be due to the lack of fertilizer. During the maintenance period, appropriate fertilizer should be applied to supplement nutrients. Also note which fertilizer is missing. If there is no phosphate fertilizer, the old leaves will be yellow first. If lack of calcium fertilizer, young leaves will curl and turn yellow. If lack phosphate fertilizer, can have no luster, old leaf first yellow. When applying fertilizer, we should choose the right kind of fertilizer according to the actual situation.
If the temperature is too high or the plant cannot adapt to the low temperature environment, the leaves will turn yellow. Therefore, in the high temperature season, more water should be sprinkled to cool down, and in the low temperature, the temperature should be controlled to provide a more suitable growth environment for plants, so as to recover and grow more vigorously.
