When rose grows, it does not have strict requirements on soil. It is more resistant to drought and barren, and can also grow in alkaline soil. But because Rosa davurica is not resistant to waterlogging, so the soil should be well drained and loose as much as possible.
When planting Rosa davurica, it is necessary to apply some mature compost as the base fertilizer first. Generally, it is not necessary to apply fertilizer again after it survives, but in order to make its branches and leaves flourish, it can apply fertilizer once after flowering every other year.
After planting, the Rosa davurica should be watered for water penetration first, and then watered once every three days or so to survive. In daily management, we should timely water according to the drought situation to avoid wilting or even death due to excessive drought and water shortage. Pay attention to drainage and waterlogging prevention in rainy season, and fill with anti freezing water once before frost.
The yellow rose should be pruned frequently.
After flowering, pruning should be carried out to remove residual flowers and dead branches, so as to reduce nutrient consumption.
After falling leaves or before sprouting, prune the old branches, dead branches and over dense and weak branches to make them grow vigorously. For the 1-2-year-old branch, it should be cut as little as possible to avoid reducing the number of flowers.
In the process of propagation, Rosa davurica mostly adopts the methods of branch propagation, strip propagation and Cuttage Propagation.
The tillering ability of Rosa davurica is strong, so it is suitable to propagate with the method of ramet propagation, because the method of ramet propagation is fast, and the survival rate is high, at the same time, it can keep the character of double petal of plant unchanged.
It is easy to cultivate, extensive in management and less in diseases and insect pests. In general, the damage of powdery mildew will appear in the growth process of Rosa davurica, which is mainly manifested in the lesions on both sides of the leaves, with sparse powdery mildew layer, which makes the leaves twisted, and the young leaves turn purple brown and die.
