1, the balcony has a flower pond, the soil layer is thin, and the soil temperature is easy to be high at noon. Excessive soil temperature will lead to root burn and limited growth of Chinese rose. Plants evaporate greatly, flowers are weak and easy to dry and die early.

2, roses like light, vines block a lot of light, making roses bloom very thin.

Solution: Thicken the soil layer, apply more potassium dihydrogen phosphate, or spray it on the leaves. Increasing the light of Chinese rose can not only eliminate all kinds of fungal diseases of flowers, but also make Chinese rose flourish, with large flowers and bright colors.
