1、 Breeding environment

1. Basin soil: purple sand basin is the best way to raise white rose. The soil with good permeability and non sticky weight should be selected as far as possible. It would be better if the soil is rich in organic matter

2. Watering: according to the principle of no drying and no watering, the soil should be kept moist as much as possible during the growth period. Generally, water should be poured once every two days. It is best not to water at noon, especially in summer. If water is poured on the leaves and then exposed to strong light, it is easy to burn them

3. Fertilization: in the growth stage of white rose, sufficient nutrients are needed, so fertilization should be carried out in time, which can be applied once a half month. Fully decomposed organic fertilizer should be used for fertilization. Do not fertilize it in the dormancy stage. At this time, it will absorb nutrients and fertilizer damage is likely to occur

2、 Common diseases and insect pests

1. Disease: the main diseases include powdery mildew, black spot or gray mold. After the disease occurs, the diseased branches and leaves should be cut off in time to avoid harming more branches and leaves, and then buy chemicals for control

2. Pests: the main pests include red spider, aphid or scale insects. When there are few pests, try to catch them manually. If there are many pests or reproduce quickly, spray them with drugs as soon as possible
