In early spring, the roots of Chinese roses begin to extend in the soil, and the most important nurturing task at this time is pruning. In warm areas, pruning should be done by the end of February, while in colder northern regions, pruning should take place between March and April. Generally, pruning involves cutting off about 1/3 of the plant's height, starting with the removal of weak, diseased, and dead branches.
The new branches that the plant produced last year are the most vigorous, and such main branches should be retained with 2 to 3 and up to 5 branches, depending on the original growth of the plant. Generally, at a height of about 50 centimeters from the ground, above a healthy bud 1 centimeter, pruning should be done with a branch剪. A healthy bud is one that is unopened, full, and swollen. In order to prevent the buds from growing into too dense branches, the healthy buds on the upper side of the plant's outer part should be selected. Additionally, pruning should be done in a full part of the branch. When pruning with scissors, a sound of "咯当" indicates a full part. If the cut feels soft, it should be cut further down to a hard place. The rough and prominent swelling parts of the branching joints of old plants have no strong buds and should also be pruned.
The middle part of the 2 to 3-year-old main branches is where new buds often appear, so only 10 to 20 centimeters should be left during pruning. If you want more flowers during the flowering period, light pruning should be done. If you want better flowering and not as many flowers, strong pruning should be done. Moreover, for plants that are not growing well, strong pruning should be done decisively, because these plants have poor root development, and if the canopy is too large, it can easily cause insufficient nutrients. It is best to do a high-concentration disinfection at the same time as pruning, which has a significant effect on preventing diseases and pests.
In order to make the pruned branches lean outward, supports (sticks, etc.) can be used to fix them, making the tree shape balanced and beautiful, and avoiding the branches and leaves rubbing against each other in the wind. The branches that sprout from the lower part of the inclined branches are stronger, and the flowers are also abundant, so they should be protected.
After the惊蛰 period, insects wake up from hibernation and start to move, and at this time, 10 milliliters of fenvalerate (insecticide) and 20 grams of wettable sulfur powder for powdery mildew control are dissolved in 10 liters of water, and the plant is sprayed with the well-dissolved concentrated solution. Since the Chinese roses have not yet grown leaves, there is no need to worry about phytotoxicity.
About 20 days after pruning, the buds start to germinate, and the weaker buds are often naturally eliminated during the germination process. To make the flowers bloom well, buds should be left according to the thickness of the main branches. Thick branches should be left with 3 to 4 buds, pencil-thick branches with 1 to 2 buds, and the rest should be removed. In cold regions, germination is later, and the time for removing buds can be postponed.
If a base fertilizer has been applied in December, no topdressing is needed in early spring. When the buds sprout, an appropriate amount of chemical fertilizer can be scattered around the roots to promote bud growth. After the buds sprout, if the ground surface is dry on sunny days, water can be poured in the morning or before noon to prevent the ground from freezing.
