How to Trim Jasmine into a Tree Shape
To make jasmine bloom with an elegant tree-like posture, pruning is an essential shaping art. As a climbing shrub, jasmine naturally grows in a bushy form. Scientific pruning not only enhances its ornamental value but also promotes nutrient concentration (G-Y). This article will thoroughly analyze the five key steps for trimming a jasmine tree shape, helping you create a graceful and upright jasmine flower tree.
One, Basic Operations for Trunk Cultivation
1.1 Key Points for Pinching the Top
Select strong vertical branches as the trunk and pinch the top for the first time when they reach 50-60cm in length. Use disinfected pruning shears to remove the top 3-5cm tender shoots, combined with removing new side buds to force nutrient backflow and promote trunk lignification. Repeat the operation every 20cm of growth until the desired height is reached.
1.2 Tool Selection Standards
It is recommended to use stainless steel pruning shears with a thickness of 0.3mm, and keeping the blade angle at 30° makes it easiest to exert force. Disinfect with 75% alcohol wipes before operation to avoid infection by pathogens.
Two, Core Steps for Shaping Pruning
2.1 Strategy for Managing New Buds
After the trunk is shaped, it is necessary to promptly remove basal suckers and new buds below 1/3 of the trunk. Retain the top 3-4 main branches and make a 45° diagonal cut when the branches reach 15cm to stimulate the growth of secondary branches, gradually forming an umbrella-shaped canopy.
2.2 Techniques for Pruning Branches
Adopt the principle of 'removing straight and retaining diagonal', pruning vertical growth branches and retaining branches that grow at a 45-60° angle. Thin out crossing branches and inward-growing branches, maintaining a spacing of ≥5cm between branches. After flowering, promptly cut back the flowering branches to the base 2-3 nodes.
Three, Root Care Supporting Measures
Combine root pruning with potting every spring, removing winding roots and diseased and rotting roots, and retaining healthy main roots 15-20cm long. After pruning, soak in a rooting powder solution for 30 minutes, then use a new matrix of ceramsite plus decomposed leaf soil (1:3) to ensure healthy root development.
Through three years of systematic pruning, jasmine can form a standard tree shape 80-120cm tall. Accompany this with phosphorus-potassium fertilizer supplements (apply potassium dihydrogen phosphate 1000 times liquid once a month), maintain 6 hours of sunlight daily, and keep the environment above 10°C in winter. Your jasmine tree is sure to bloom with fragrant white flowers year after year, becoming an elegant focal point in the courtyard.
