1. Treating pests and diseasesRoses are easily infected by diseases and pests, such as powdery mildew, black spot, downy mildew, and insect pests such as red spider mites and caterpillars. These diseases and pests will affect the performance, causing leaves to fall, resulting in bare stems. Effective prevention is needed before the disease occurs, avoid contact with infected plants, increase ventilation, and do not maintain them in a stuffy and airtight environment. When pests and diseases appear, cut off the diseased leaves in time and then spray pesticides for treatment. 2. PruningAfter the rose stems are bare, they will sprout again after about 1 to 2 weeks. If they sprout at the same time, it will be difficult to supply water and nutrients, causing the new shoots to wilt and wither. The branches need to be cut short in time to reduce nutrient consumption and promote the growth of new buds. 3. Control moistureAfter all the leaves fall off and the plant becomes bare, photosynthesis will decrease and the demand for water will also decrease. In fact, if you continue to water it according to the previous method, the roots will find it difficult to absorb water, which will cause root rot and affect the growth of the entire plant. You can control watering and increase light to encourage re-sprouting. |
