Rose pruning should be based on the rose species, cultivation purposes, and the status of branches, to determine the length of the rose branches, how much and length. The first is the difference between high and low; the plexiform rose planted on the green land requires the plants to grow taller and more flowering. The flowers are not required to be particularly large and should be cut more. Generally, only 3 to 5 sturdy 1 to Stem of 3 years old, with a height above 70 cm, with about 10 to 15 shoots per stem. Cut off the upper part of the stem, but be sure to distribute 3 to 5 stems evenly, except for a few strong shoots at the base. Prepare to replace the bad winter branches in the future, all other branches will be cut off. For the abyssal rose growing on a flower bed, it is not required to grow particularly tall. You can choose to leave 3 to 5 strong stems. Each stem should be kept between 30 and 40 centimeters. It contains about 6 to 8 buds. Cut it out and remove the messy branches of it. For potted rose, in addition to leaving 3 litters of 120 branches per plant, leave only 10 to 15 centimeters per branch with 2 to 3 shoots. The second is to keep the inferiority; for bad branches, thin and thin branches, branches and branches, cross branches, and inner litchi, all must be cut from the base. The selected must be strong and healthy one to three-year old branches. Pay attention to check whether there are any insect pests in the stem. If it is found, it should be cut off as soon as possible to prevent it from harming again after winter. Pruning should be done with a knife to avoid squeezing the cuts due to the bluntness of the blades, causing the cuts to break and affecting the sprouting of branches in the coming year. The cut branches and the cleaned leaves can be burned together. The third is to cut the anvil to protect the ear; the pruning of the rose seedlings of the grafted seedlings should be especially careful. Firstly, look for the grafting site. The branches and sprouts on the rootstock must be completely cut off or erased to avoid germination in the coming year. For the branches above the grafting site, one or two years of strong branches can be selected, and each branch can be kept at a certain angle to make it evenly distributed, and retain 5 to 7 full-filled eyes at the base, and then cut the rest of the branches. After the pruning is completed, the basal fertilization should be applied in time for the ground-planted rose, the pot-planting rose should be given a change basin, and the plants should be sprayed with lime sulfur mixture one or two times, which can effectively reduce the occurrence of pests and diseases in the coming year.
