How to prune roses during their dormant period
Today's focus is on introducing you to the content about roses, specifically how to prune roses during their dormant period. Here is a comprehensive introduction.
Pruning potted roses during their dormant period is best done when the auxiliary buds at the end of the dormant period begin to swell. In the south, this is usually from mid-January to the end of February, while in the north, pruning is often done from February to the end of March. During the dormant period, pruning mainly involves cutting away dead branches, diseased and pest-infested branches, intersecting branches, weak and thin branches, as well as tender branches that sprout in autumn. Then, depending on the characteristics of the rose variety, pruning is carried out in three ways: strong, medium, and weak.
(1) Strong pruning. This is done on weaker plants, usually removing 2/3 of the entire plant, leaving 2 to 4 main branches. This method is often used for large-flowered potted roses.
(2) Medium pruning. This is done on plants with normal growth and a symmetrical shape, cutting about 1/2. This method is suitable for varieties that easily produce new shoots and bloom frequently.
(3) Weak pruning. This is applied to vigorous plants, cutting about 1/3. Varieties like the flowering rose are suitable for this pruning method.
The tools used for pruning, such as knives and shears, should be sharp to ensure smooth cuts and prevent splitting of the branches. It is important to select auxiliary buds that grow outward, and the cut should be about 0.5 cm above the auxiliary bud,倾斜 at a 45-degree angle inward. This type of pruning allows the branches to spread evenly outward, maintaining good ventilation and light for the plant. For one-year-old potted seedlings with new branches taller than 30 cm, about 2/3 should be cut, and for those shorter than 30 cm, about 1/2 should be cut. Very small plants may not need pruning. For roses planted in the ground that overwinter outdoors, avoid strong pruning in the late autumn to prevent wind-damaged branches. Pruning should be done after thawing in the spring.
