Rose Pruning
As one of the three treasures of the courtyard, pruning is the key operation that determines the amount of flowers the rose produces. Many rose enthusiasts often cause the plants to grow excessively without flowering due to improper pruning during maintenance. This article will systematically analyze the pruning points from the seedling stage to the mature stage, with exclusive illustrations to help you easily master the essence of pruning.
Golden Rules of Rose Pruning
Key Operations in the Seedling Stage
1. Forced removal of primary flower buds: Retaining flower buds in the seedling stage will consume more than 60% of the nutrients. It is recommended to剪 (cut) the buds flat with a disinfected scissor at the early stage of bud formation, and spray potassium dihydrogen phosphate to promote the lignification of the main branches.
Pruning Standards for Adult Shrubs
2. Three-level branch pruning method: Keep 3-5 buds on the main branches, 2-3 buds on the secondary branches, and 1-2 buds on the tertiary branches. The cut should be 0.5cm away from the bud and at a 45° angle to ensure that new branches can sprout from each pruning surface.
Techniques for Handling Special Branches
3. Identification of blind branches and buds: Branches with more than 5 leaves that have not formed buds should be cut back by 1/3,交叉枝 (cross branches) should retain the outer buds, and inward branches should be thoroughly removed from the base to ensure the ventilation and light transmission rate of the plant is over 70%.
Advanced Maintenance Tips
Control of Pruning Cycles
1. Seasonal pruning differences: Prune heavily in spring, leaving 15cm main branches; lightly in summer to remove spent flowers; moderately in autumn, leaving 30cm branches; and shaping pruning can be done during the dormant period in winter. The interval between each pruning should maintain a growth period of 15-20 days.
Tool Disinfection Standards
2. Double disinfection process: First wipe the blade with an alcohol swab, then burn with an open flame for 10 seconds. Repeat disinfection before pruning different plants. It is recommended to use the Japanese ARS folding shears, as its 0.3mm ultra-thin blade can reduce tissue damage.
Key Points for Wound Protection
3. Wound healing treatment: Cuts larger than 1cm in diameter should be coated with Japanese Sumitomo园艺 healing agent, and small cuts can be sealed with beeswax. Avoid rain within 3 days after pruning and recommend using brassinolide to promote wound healing.
Mastering scientific pruning methods can increase the annual flowering amount of roses by more than 3 times. It is recommended to choose the pruning intensity based on the age of the plant, with the focus on root growth in the seedling stage and appropriate heavy pruning for plants over three years old. Regularly observe the sprouting of new buds and coordinate with watering and fertilizing to create a continuously flowering rose wall.
