The shrub rose has a large number of flowers and a long flowering period. The soil needs nutrition, looseness and good drainage, so it can't be planted in a poor place. It needs a certain amount of light to give, so as to maintain good growth, synthesize enough nutrients, and cannot be planted in the dark and dark place. Water and nutrients must be sufficient, if lack of water and fertilizer, growth will be hindered.
If it is planted indoors, it is necessary to ensure good ventilation, open more windows for ventilation, and promote the circulation of fresh air. If it is sultry and not ventilated for a long time, the growth will also have problems.
1. Summer: the sunshine is very strong in summer, and the water evaporates a lot, so the amount of water in summer should be more. At this time, the growth is basically stagnant and no more fertilization is needed. In summer, the sun is very strong, so we need to cover the hot sun, not direct light.
2. Overwintering: Although the shrub rose can withstand cold, it should be moved indoors for maintenance as far as possible. For outdoor maintenance, it needs to be pruned and then covered with straw to help survive the winter.
Shrub rose is mainly pruned in winter dormancy stage, first pruning dead branches and diseased branches, removing weak branches, then cutting one third of the main branches and two thirds of the side branches.
