When is jasmine pruned in spring?
Jasmine is a common aromatic plant in the courtyard. The timing of pruning directly affects the quality of flowering and plant health. Mastering the "three-season pruning method" can not only maintain beautiful plant types, but also stimulate flower bud differentiation, allowing the fragrance to last throughout the growing season. 1. Key tips for spring pruning 1.1 The best time window is when the temperature stabilizes above 15℃ and new buds germinate 1- 2 cm. It is mostly in mid-March in the south, and in the north it is extended to early April. Pay attention to avoid the late spring cold period. 1.2 Specific operating steps use disinfectant branch scissors, prioritize cutting off cross branches and inner branches, and retain 3-5 nodes of the main branch. Keep 3 pairs of leaves on the top branch and 2 pairs of leaves on the lateral branch. Apply Yushang Cream immediately after pruning. 2. Autumn maintenance pruning 2.1 Points for pruning after flowering Within 15 days after the last flower withers, retract the branches to the second pair of leaves and clean up the withered leaves at the same time. At this time, phosphorus and potassium fertilizers can be combined with the application of phosphorus and potassium fertilizers to promote the lignification process. 2.2 Shape maintenance techniques are used to pick the long branches to keep the crown uniform. Each branch retains 2-3 branch points to form a "chicken claw" skeleton to accumulate energy for overwintering. 3. Deep shaping and pruning in winter 3.1 The pruning intensity is such that 1/3 of the total branch quantity can be removed after falling leaves are controlled to before germination. Focus on cutting off pest and insect branches and thin and weak branches, and retaining 3-5 bud points at the base of the main branch to form a "bowl-like" transparent structure. 3.2 Wound management is standardized. Thick branch incisions require 45° oblique cuts and special sealing wax is applied. After pruning, lay a 5cm thick pine needle cover to prevent freezing damage and adjust the soil pH.
Mastering the three-season pruning rules for jasmine and cooperating with water and fertilizer management, you can achieve 4-5 cycles of flowering per year. Special attention should be paid to tool disinfection and wound protection to avoid bacterial infection. Regular pruning can not only enhance the ornamental value, but also extend the life of plants to more than 10 years.
