Do roses need pruning?
Rose pruning is a key technology to keep plants healthy and promote flowering. Scientific pruning can not only create elegant plant types, but also enhance disease resistance and extend the flowering cycle. Through seasonal pruning management, roses can be maintained with strong vitality and achieve flourishing flowers year after year. Core tips for rose pruning 1. Spring rejuvenation pruning Carry out structural pruning before germination in early spring, retract the old lignified branches to the base 3-5 buds, and retain strong main branches with a diameter of> 0.6 cm. Use a 45-degree oblique cut method to prune crossed branches, with the cut 0.5cm away from the bud eye to promote the germination of new buds. Combined with the application of decomposed organic fertilizer, the growth rate of new branches can be increased by 40%. 2. Fine trimming of residual flowers after flowering needs to be completed within 7 days after flowering, and cut down from 0.8 cm above the fifth compound leaf at the base of the branch. Remove thin and weak branches (diameter <0.3cm) simultaneously, and retain outward and plump buds. Retain 8-12 main branches per square meter to ensure ventilation and light transmission of the plant, which can reduce the incidence of black spot by 65%. 3. Mild pruning is carried out 2 weeks before the winter protective pruning frost, leaving the trunk height of 60-80cm. Focus on removing pests and diseases, and apply healing agents to the incision to prevent frostbite. Retaining a suitable amount of leaves for photosynthesis and combining with soil cultivation to prevent cold can increase the survival rate of plants through winter to 95%.
Systematic pruning management can make roses bloom 2-3 more rounds every year. It is recommended to equip professional pruning shears (blade length 8-10cm) and spray carbendazim solution for disinfection after each pruning. By mastering the pruning principle of "promoting hair growth in spring, maintaining shape in summer, and protecting root in winter", you can harvest rose bushes that continue to bloom.
