Does茉莉 need a complete pruning in spring?
As the king of courtyard fragrance, the spring maintenance of茉莉 directly affects the quality of flowering throughout the year. Among them, the pruning process is particularly crucial, as it should neither be left uncontrolled nor overly pruned. It is necessary to master scientific pruning methods to allow the plant to burst with vigorous vitality.
Ⅰ. Core Principles of茉莉 Spring Pruning
1.1 Misunderstanding of Complete Pruning
Jasmine should not be completely pruned in spring, as retaining the main branches can maintain the photosynthetic capacity. Experimental data shows that plants with more than 30% of branches and leaves retained sprout new buds 2-3 weeks faster than those that are fully pruned, and the flowering amount increases by 40%.
1.2 Layered Pruning Strategy
It is recommended to use the '333' pruning method: retain 1/3 of the vigorous branches, prune 1/3 of the weak branches, and cut back 1/3 of the overgrown branches. This ensures the plant's vitality while promoting the sprouting of new branches.
Ⅱ. Four-Step茉莉 Systematic Pruning Method
2.1 Precise Pinching to Promote Branching
When the new shoots grow to 3-4 pairs of leaves, leave the base 2 pairs of leaves and pinch the top. This operation can cause a single branch to differentiate into 3-5 new buds, and when combined with weekly phosphorus-potassium fertilizer, it can increase the flower yield by 60%.
2.2 Scientific Thinning to Shape the Plant
Follow the principle of 'remove inner branches, retain outer ones; remove weak branches, retain strong ones.' First, prune the inward and crossing branches, then thin the dense ones. Maintain a branch spacing of 5-8cm to ensure ventilation and light.
2.3 Root Synergy Pruning
When repotting, remove the brown old roots and retain the white new ones. After pruning the roots, soak them in ABT rooting powder, which can double the amount of new roots that sprout.
2.4 Wound Care Tips
Prune at a 45-degree angle to ensure a flat cut surface; wounds with a diameter over 0.5cm need to be coated with healing ointment. Avoid rain within 3 days after pruning and use a fungicide solution of 800 times to prevent infections.
Ⅲ. Post-Pruning Maintenance System
After pruning, adopt the 'three controls and three supplements' maintenance method: control watering frequency (water only when the potting soil is completely dry), control the amount of nitrogen fertilizer, and control the intensity of sunlight; supplement trace element fertilizers, supplement EM bacteria solution, and supplement scattered light. After 20 days of such maintenance, the plant will enter a vigorous growth period.
Scientific pruning is the key to茉莉 spring maintenance. By combining layered pruning with systematic care, it not only shapes an elegant plant form but also increases the flowering amount by over 50%. Remember the eight-character maxim 'Prune when needed, retain what should be retained' to make茉莉 bloom even more brilliantly in spring.
