Pruning and pulling of vine roses
As a star plant in courtyard landscaping, the ornamental value of vine rose is closely related to maintenance skills. Scientific pruning and reasonable traction can not only increase the amount of flowering, but also create a unique three-dimensional flower wall effect. Mastering the following core operating points will make your vine rose bloom with amazing charm during the peak growing season. Three elements of vine rose pruning 1. The old branch renewal strategy requires focusing on the treatment of lignified branches over three years old, and retaining the base 15cm to promote the germination of hidden buds. Pay special attention to the thorough removal of crossing branches and insect and insect branches, and apply Yuhang Cream immediately after pruning to prevent infection. The best operation time is 2 weeks before flower buds sprout in early spring. 2. Fine management of flowering branches Select strong flowering branches with a diameter of more than 0.5cm and retain 2-3 plump buds that grow outward. The principle of "removing three and leaving two" is adopted for branches with too dense top flowers to ensure that the spacing between each bud point is not less than 8cm, so that nutrients can be supplied in a concentrated manner. 3. New branch control techniques Long branches without differentiated flower buds need to be picked to retain 4-6 true leaves. For branches with excessively strong top dominance, lateral branch folding can be used to stimulate the germination of lateral buds, and phosphorus and potassium fertilizer spraying can be combined to promote flower bud differentiation. Four-step method for pulling vine rose 1. The three-dimensional support system builds a preferred anti-corrosion wood grid or galvanized steel frame as the support, and the grid spacing is controlled at 15-20cm. A ventilation gap of 5cm needs to be maintained for wall traction, and X-shaped cross fixation method is recommended for arch shape. 2. The branch direction planning follows the principle of "strong branches are at high positions and weak branches are at low positions." The main branches are pulled at a 45° angle. When fixing with plastic wrap straps, 2 cm of growth space is reserved, and a fixation point is set every 30cm to prevent slippage. 3. Light balance adjustment ensures that each leaf receives more than 4 hours of light per day through staggered distribution of branches. The south-facing wall adopts fan traction, and the east-facing wall adopts a spiral upward layout. The direction of the potted plant is rotated regularly to eliminate phototropic bending. 4. Dynamic maintenance and management check the tightness of binding every two weeks during the growth season, and replenish the binding in time after new branches are stretched by 20cm. Strengthen the support system before the rainy season, and carry out branch reset immediately after windy weather.
Through systematic pruning and traction management, the annual growth of vine rose can be increased by more than 40%. It is recommended to combine deep plowing fertilization in winter with shade and moisturizing in summer, and use biostimulants to enhance plant stress resistance, so that your rose flower wall will become a three-dimensional picture that has lasted for years.
