1、 Curing method

1. Soil: red roses like more fertile soil. When planting, you can choose more fertile sandy soil. This kind of soil has good drainage performance and strong drainage. Do not use clay. Its air permeability is poor, which will affect the development of plant roots and reduce its flowering effect

2. Light: the growth of red roses requires a lot of light, which should be guaranteed for at least four hours a day. If you don't touch the sun for a long time, the leaves will turn yellow

3. Temperature: the red rose needs a relatively mild growth environment. The suitable growth environment for the red rose is the temperature from 12 degrees to 28 degrees. Because of the cold weather in winter, roses should be moved indoors for breeding

4. Moisture: red roses are not resistant to waterlogging, but moisture is also essential. When the surface is dry, you must pay attention to watering, but also pay attention not to ponding, which will lead to root rot

2、 Breeding skills

1. Pruning: usually do not need to prune too much. During the dormancy period, prune the withered branches and pest branches. In winter, the branches and leaves ten centimeters away from the ground should be cut off to ensure a smooth winter

2. Transplantation: the transplantation of red roses should wait until all the leaves have fallen. It's OK to expose the root or bring some soil all the time. Fertilization should be carried out half a month after transplantation. In summer, we should pay attention to irrigation and avoid water loss. Pruning should be carried out in autumn to promote metabolism

3、 Problem diagnosis

1. Black spot: carbendazim, dakonine, methyltobuzin and other drugs can be sprayed for treatment

2. Leaf spot: clean up the diseased leaves in time. In the early stage of the disease, one percent Bordeaux liquid can be used for spraying, and once every half a month. It can also be treated with fifty percent times of zinc spray 800 times. p>

4、 Other issues

1. Indoor breeding: because red roses like light and need plenty of sunshine, it is recommended to breed them in a place with sufficient light. To be more ventilated, it is recommended to breed on the outdoor balcony. In winter, we should pay attention to indoor breeding to avoid it from freezing

2. Flowering time: the flowering period of red roses is about April and may, and the natural flowering period is from May to November. It can bloom continuously. When flowering, we must pay attention to the light. If the light is insufficient, we can't bloom. It should also be provided with sufficient sunshine and water during flowering
