【Two, Causes of withered leaves in rose shrubs and treatment methods】
<1. Excessive watering>
Although rose shrubs enjoy a humid environment, it is not advisable to water blindly. Excessive watering can cause the leaves to turn yellow or even wither, leading to death in no time. In this case, it is necessary to control the amount of water and follow the treatment methods.
Treatment: For severely affected plants or where waterlogging is difficult to eliminate, the plant should be cut back, lifted to a higher position, and then replanted. For those slightly affected, you can use the method of piling soil at the base of the plant to stimulate the formation of adventitious roots, thereby alleviating the situation.
<2. Over-fertilization>
Sometimes, to make the rose shrub grow better, we might fertilize excessively. However, over-fertilization can cause root burn, which in turn can lead to withered leaves or even death.
Treatment: First, remove the rose shrub from the potting soil, replace the soil in the pot, and then transplant the rose shrub into the pot with new soil to effectively solve the problem of withered leaves.

In the early stage of the disease, the leaves look as if they are floating with uneven white powder. In the middle stage, the area gradually increases; in the later stage, the white powder thickens and becomes fluffy, covering the compound leaves. Soon, the leaves become soft, twisted, and the petioles hang down in a disheveled manner.
Treatment: Check the plant body around the autumnal equinox and Qingming. Inject 80%敌敌畏 emulsion 5 to 10 times into the虫孔, then seal the mouth with mud to kill the longicorn larvae. For other leaf-eating pests, you can spray 800 times the duration of the phosphorus pesticide to kill eggs and larvae, effectively preventing and controlling leaf-eating pests.
<4. Poorly ventilated growing environment>
The growing period of the rose shrub is from March to November. The most important growing condition during this period is good ventilation. A poorly ventilated environment will cause the rose flowers to wither rapidly, leaves to fall, and branches to die.
Treatment: Cut off the withered leaves, move the rose shrub to a well-ventilated area, and care for it for a while. If it still doesn't improve, you may have to resort to cutting. Therefore, be careful not to place it in a poorly ventilated location during maintenance.
<5. High temperature>
Rose shrubs are warm-loving plants that do not tolerate direct sunlight. High or low temperatures can cause the leaves to turn yellow and even wither. In the summer, it is advisable to provide some shade to lower the temperature.
Treatment: First, place the rose shrub in a shady place, then water it, cut off all the withered leaves, and place it in a semi-shaded area for care. It won't be long before it can recover its vitality.
