At the end of summer and the beginning of autumn, the growth of rose is usually not good, and there may be flowers on the branches. Cut the flowers in time, and bury a handful of chicken manure or slow-release fertilizer beside the basin.
The purpose of burying chicken manure or slow-release fertilizer is to supplement phosphorus and potassium fertilizer for the plants first, promote the root growth of rose, and rejuvenate the branches, so that the growth will be faster after 10 days of pruning.
If your rose is strong, you can skip the first step and cut it directly in early September. The principle of pruning is to remove the weak and retain the strong, so as to avoid blind branches and buds to the greatest extent.
First of all, we need to trim the thinner branches, and we need to cut down at 1cm above the full bud point of the branches. If there is no bud point on the branches, we need to trim according to the overall pruning height of the plant.
Then observe whether there are parallel branches. If there are, cut off the weaker branch. But if the two branches have the same thickness and there is no bud on the relative old branch, cut off the old branch and keep the new branch with stronger vitality.
Rose flowers many times a year and prunes many times. By the end of summer, each branch often has multiple cuts. The more upward branches grow, the thinner they will be. Therefore, it is necessary to cut back at the beginning of autumn. According to the growth of the plant, cut them down at the circle.
Finally, the overall plant type should be adjusted, the thin branches and Cross branches should be cut off, and the pruned branches should be at the same level as far as possible, so as to ensure that the rose of each branch is open at the same time.
The bud points of each flowering branch should be cut everywhere in the same horizontal plane as much as possible, and blind branches and buds can also be prevented. Otherwise, rose has a very strong top advantage. If there are some branches that are too low pruned, it is possible to develop blind branches at the end without flowering.
For the pruned rose, if it can be exposed, it should be exposed. If it can't be moved out, it should be placed on the south balcony and window as far as possible. The basin should be rotated frequently to open the spacing between the potted plants and reduce the mutual shielding between the plants.
Do not try to water once for a fixed number of days, especially when the temperature changes rapidly. You can often weigh a flowerpot. You can feel that the soil in the basin is obviously lighter. Water it in time until there is water flowing out of the vent hole at the bottom of the basin.
