Every spring is the peak season for Chinese roses to bloom, and the biggest flower is in spring, because after a winter break and three or four months of nutrient accumulation, the flowers in spring will burst directly, and it is best to prune Chinese roses in spring before germination.
1, pruning
Actually, pruning is nothing special. The main thing is to remove some diseased branches and weak branches, remove some branches that are too prosperous, and leave the strongest branches. There's nothing special about it. If 1/3 can be directly removed from the outdoor bush roses, for vine roses, the main thing is to straighten out the branches, climb them to the wall, stretch them and make beautiful shapes. It will be fine when it blooms evenly.
Step 2 bask in the sun
In addition to pruning, the most important thing is to apply fertilizer to bask in the sun and prevent pests and diseases. The most important thing is that we prune, which belongs to human intervention. Many kinds of roses in the ground will still bloom if they are left alone, but the flowering may be uneven.

If you want to make the rose blossom tangible, you can appropriately reduce the crown width, increase watering and fertilization and post-management
Step 4 apply fertilizer
When Chinese roses germinate in spring, the demand for nitrogen is particularly great. Sometimes nitrogen, potassium or compound fertilizer can be supplemented and watered 1 22 times a month until leaves grow. Then, you can apply some compound fertilizer to it, and when it has buds, spray or water it directly with phosphorus and potassium fertilizer to make the buds fully spread.
5, pests and diseases
In spring, the leaves of Chinese rose are especially tender, so it is easy to get sick, so spray fungicides or pesticides every other week or 10 days to prevent its pests and diseases. You can prepare some small white medicines to prevent insects, as well as carbendazim, chlorothalonil and imidacloprid.
