How to Prune and Shape Aglaia odorata
As a common fragrant plant in gardens, the pruning and shaping of Aglaia odorata directly affects the amount of flowers and its ornamental value. Mastering scientific pruning times and methods not only creates a beautiful tree shape but also enhances the plant's disease resistance. This article will systematically analyze the key points of pruning and maintenance of Aglaia from the growth cycle to shaping techniques.
Three Elements of Pruning and Shaping Aglaia odorata
Best Time for Pruning
Pruning Aglaia odorata should follow the principle of "Shaping in Spring and Maintenance in Autumn": 1. Seedling stage (March-May): The first pinching should be done when the main branches are 15-20 cm high. 2. Growing period (November): The golden pruning period 7 days after flowering. 3. Shaping period (March-April): Completing the framework shaping before germination. Special attention should be paid to avoid pruning during the winter dormancy period, as the wounds heal slowly and are prone to disease infection.
Step-by-Step Shaping Techniques
1. Basic shaping: Use the pinching method in the seedling stage, retaining 3-4 main lateral branches to form an umbrella-like framework. 2. Detailed pruning: Thin dense branches before flowering, retaining healthy flower buds with a spacing of 2 cm. 3. Artistic shaping: Create special shapes like cloud-like or cliff-like forms through coiling and牵引. 4. Diseased branch treatment: Immediately cut off withered branches and apply healing agents to prevent infection.
Special Period Maintenance
• After pruning in the plum rain season, spray Mancozeb to prevent black spot disease. • Remove the withered flowers in time after flowering and apply phosphorus and potassium fertilizers. • Shaping adjustments should be done in the morning on sunny days, avoiding high-temperature periods. • Tools should be disinfected with alcohol to prevent cross-infection.
Advanced Guide to Shaping Aglaia odorata
For plants over five years old, it is recommended to: 1. Synchronize root pruning with pot changing every spring. 2. Use the broken stem bending technique to shape robust branches. 3. Adjust the direction of branches with aluminum wire coiling. 4. Retain an appropriate number of adventitious buds to enhance the层次感 of the canopy.
Scientific pruning of Aglaia odorata can not only increase the flowering amount by 40% but also form the classic "three branches and nine tops" shape. It is recommended to adjust the pruning intensity according to the light angle, increase the thinning density for south-facing plants, and retain more leaves for photosynthesis in north-facing plants.
