Detailed Explanation of Rose (Chinese Rose) Cultivation Methods and Care Techniques
Chinese rose, also known as "monthly red," is called the queen of flowers. It blooms in all four seasons, with beautiful and elegant flowers in diverse colors. It is deeply loved by people and has extremely high ornamental value. In addition, it can also be used as a medicinal plant with certain economic benefits. So how should Chinese roses be cultivated? Let's take a look at the detailed introduction.
1. Suitable Growing Environment
Chinese roses do not have high requirements for climate and soil, but fertile, loose, well-drained, organic-rich, slightly acidic soil is preferable. Sandy loam, heavy clay soil, and poorly drained soil can easily cause root rot. Chinese roses prefer warm environments with ample light, so an area with sufficient direct sunlight is needed, 6-8 hours per day. The maximum light time is best in the morning, with less sunlight in the afternoon, to prevent wilting caused by strong afternoon sun.
2. Selecting Good Varieties
It is best to choose varieties that are suitable for local sale. Some varieties can grow in extremely hot environments, but their cold tolerance is relatively poor. When planted in areas with low winter temperatures, if cold protection work is not adequate, they are very susceptible to frostbite or freezing to death. Therefore, cold protection work should be done well in winter. A 5 cm layer of peat can be covered at the root and stem base to raise the temperature and prevent root frostbite. For smaller varieties, a box can be used to cover the entire plant to prevent snow accumulation, and snow on the flowers should be regularly cleared. If the planting area is too large, a frame with a cover can be set up.
3. Fertilizing and Watering
Generally, the first fertilization is carried out after spring warms up. Fully decomposed organic fertilizer should be given at once in sufficient quantity. After the Chinese rose recovers and begins to grow, quick-acting fertilizer should be supplied to promote its growth. Only when soil fertility is sufficient will its growth accelerate. During the growing period of Chinese roses, regular fertilization is needed to promote flowering. When fertilizing, attention should be paid to alternating the use of compound fertilizer and phosphorus-potassium fertilizer to promote balanced plant nutrition. Watering Chinese roses should avoid being overly frequent. When watering, it should not be poured on the branches and leaves, nor should the entire plant be directly sprayed with water. Watering at night is not advisable, as residual water on branches, leaves, or flowers may cause black spot disease or leaf spot disease. The soil should also not remain constantly moist, to avoid inducing fungal diseases. Follow the principle of watering when dry and stopping when wet, and not watering until the soil is completely dry.
4. Pruning
To make the plant shape graceful and produce more flowers, pruning is essential. Promptly cut off some rotten black stems and some withered, diseased branches and leaves, which can also prevent diseases. Pruning off the branches at the bottom of the root and stem can increase the ventilation at the root and stem area and avoid the breeding of pests and diseases.
