First, the pruning time
The pruning time of wild rose in the south and the north is different. Pruning of southern Rosa multiflora generally occurs from mid-June to late February in 65438+ 10, while pruning of northern Rosa multiflora generally occurs from February to March.
Second, the pruning method
1. How to prune new buds after they grow?
After the new buds germinate, they need pruning. Pruning at this stage will not have any effect on the growth of roses. Of course, flower friends should also check whether there are buds and leaves growing on the stems and leaves. If there are no buds on the stems and leaves, you can't prune them immediately after they grow, and then prune them a few weeks later.
Specific pruning method: if the young branches grow tall, about 2/3 of the parts over 30 cm should be cut off. If the new shoots of the seedlings are short and do not reach 30 cm, they need to be cut off about 1/2. If the plants are small, they can be pruned.
2. How to trim the dormant period?
After first frost, Rosa davurica will be dormant, whether in 65438+ 10 or February, mainly depending on the local temperature.
Specific pruning method: cut off dead branches, diseased branches, overlapping branches and twigs from the bottom. Shoots that germinate after autumn should also be pruned.
3. How to prune after flowering
Pruning can avoid the occurrence of rose diseases and insect pests after the flowering period of wild rose.
Specific pruning methods: Different varieties of roses have different pruning times. Some roses can be pruned after flowering, while others need pruning during dormancy. If roses grow new branches in spring and there are flowers on the new branches, such roses can be pruned during dormancy. Some roses bloom on old branches, and these varieties need pruning after flowering. Prune after flowering, and generally leave about 20 cm of branches. For those seedlings that have just grown 1 year, the branch length should be kept at about 30 cm. If the plant is short, cut off half the branches.
Third, matters needing attention
Scissors should be sharp, disinfected before pruning, and disinfected every time pruning, keeping a 45-degree angle. After pruning, a layer of plant ash or a layer of white glue can be coated on the incision, which can play a role in disinfection.
