Rosa belongs to Rosaceae, which can be propagated by sowing and cutting. Rare species are difficult to cut and can be propagated by layering and grafting. Common varieties include wild rose, pink rose, lotus rose, Huang Qiangwei, French rose, Rosa densiflora, Bai Yutang, Seven Sisters and Begonia rose.

Rose cultivation method

Roses like sunny environment and can accept semi-shade. If the culture environment is well lit, the requirements for soil are not high, and it can grow in ordinary clay. When planting, some base fertilizer can be applied, and the curing temperature is best at 15-20℃. Roses are plants that are afraid of water accumulation, so just don't water them too much when maintaining them, because the soil is slightly wet.

In the wild rose, we should choose loose, fertile and well-drained slightly acidic soil, and it is best to follow the principle of "seeing dry and seeing wet" when watering. The growth of Rosa davurica needs sufficient sunshine and belongs to all-day plants. When the growth is vigorous, decomposed fertilizer water should be applied every half month, and phosphorus and potassium fertilizer should be applied 2-3 times before flowering.

Watering method

In spring, roses begin to grow again. At this time, the air humidity is high. Check the pot soil every half month to see if it needs watering. In summer, water is poured once every 10 day, and appropriate amount of water can be sprayed to keep moisture. The temperature is low in autumn and winter, so reduce watering and ensure that the basin soil is dry.

Fertilization method

Rosa multiflora is a plant that loves fertilizer. Fertilization should be carried out in accordance with the method of "thin application and diligent application" Fertilization in winter can be combined with soil cultivation once, which can ensure that shoots and flower buds have enough nutrition, branches and leaves are more lush, and bloom is more gorgeous. During flowering, the frequency of fertilization is changed to one or two times a week, so as to ensure the yield of flowers.

Pruning method

Roses can be pruned when new buds sprout, and the branches can be cut off above the bud eyes. The dead branches should be pruned immediately, and the sparse, overlapping or cross-growing branches and leaves should be pruned. After the flowers wither, trim the residual flowers and remove the weeds around the plants.

Matters needing attention in rose cultivation

1. During the curing period, it is necessary to improve its growth conditions, maintain good ventilation, reduce the use of nitrogen fertilizer and increase the use of phosphorus and potassium fertilizer.

2. Roses are prone to powdery mildew under the conditions of poor ventilation, insufficient light, heavy rain and wet soil, and need to be cut off immediately.

3. During the management of Rosa davurica, we must pay attention to ventilation and prune the branches and leaves frequently, otherwise it is easy to catch diseases. Once the disease is found, it should be treated as soon as possible and sprayed with drugs to avoid deterioration.
