Although Yushu is a light-loving plant, the stronger the light, the better. It cannot stand strong light exposure. Once it is exposed to the hot sun for a long time, the stimulating strong light will directly shine on the leaves, causing the leaves to be burned and turn yellow.Especially for the newly transplanted Yushu, it can not see strong light, at this time the growth is not stable, rashly see strong light will lead to plant dehydration, and even affect the growth of the plant.Once the situation of yellowing occurs, it is necessary to transfer the maintenance position and move to the shade to promote recovery.
1, too little light: not only strong light will lead to Yushu leaves yellow, the lack of sunlight will also cause yellow leaves, should be reasonable light.

3, improper fertilization: lack of fertilizer or fertilization too much, will have an impact on plant growth, causing the problem of yellow leaves.If there is a lack of fertilizer, it should be given in time to ensure the supply of nutrients, if there is too much fertilizer, it is necessary to control fertilization and water dilution in time.
4. Effects of plant diseases and insect pests: Plant diseases and insect pests are also one of the reasons. If you are not careful to catch plant diseases and insects, it will also cause the leaves to turn yellow.Can pay attention to good protection, after the emergence of timely spraying treatment.
