How to Train茉莉 into a Tree Shape
Among numerous household green plants,茉莉 is deeply loved for its elegant shape and refreshing fragrance. Training茉莉 into a tree shape not only enhances its ornamental value but also improves the plant's ventilation and light penetration. To achieve this, it is necessary to master systematic cultivation methods such as soil improvement, shaping pruning, and nutrient control.
Basic Cultivation Preparation
Soil Matrix Configuration
Use a 5:3:2 ratio of humus soil, coarse river sand, and fermented pine needles to ensure the matrix is loose and breathable with a slightly acidic pH. Every two years, mix bone meal into the pot when repotting to supplement calcium, which can effectively promote the lignification of the main stem.
Principle of Container Selection
Choose a deep cylindrical ceramic pot to cultivate the tree-shaped茉莉, with a pot depth of at least 35cm to ensure vertical root growth. Replace the pot with a larger one every spring before sprouting, and place it in a scattered light environment for 7 days after repotting before resuming normal care.
Techniques for Shaping the Tree
Main Stem Cultivation Stage
Retain 1-2 strong main branches as the shaping trunk and continuously remove lateral buds at the base 30cm. When the main stem reaches 50cm in height, perform the first topping to stimulate the growth of upper lateral branches to form an umbrella-like canopy.
Support and Shaping Method
Use a three-legged bamboo frame to secure the main stem and tie with hemp rope in an 8-shape knot. When new branches reach 15cm, shape them by bending and guide them to extend horizontally with aluminum wire.
Nutrient Control Management
Fertilizer Ratio Scheme
Apply a nitrogen-phosphorus-potassium (15-10-20) liquid fertilizer weekly during the growing season from March to June, and add monopotassium phosphate in September to promote lignification of branches. Stop fertilizing during the winter dormancy period and use EM bacteria solution to improve soil activity.
Maintenance of Acid-Base Balance
Test the soil pH value monthly, and when it exceeds 6.5, water with a ferrous sulfate solution in a 1:1000 ratio. Combined with the application of mature rice water, it can maintain a slightly acidic soil environment.
Key Points for Environmental Optimization
In the summer noon, provide 40% shading to ensure 4 hours of direct sunlight daily. Maintain air humidity between 60%-70% and use the pot-in-pot method to keep the roots moist. Regularly rotate the pot to ensure even light exposure to the canopy, and perform shaping pruning every winter to maintain an elegant tree shape.
Through systematic cultivation measures,茉莉 can form an elegant tree shape within 3-4 years. The key is to grasp the rhythm of nutrient supply during the growing season and shaping pruning during the dormancy period, combined with appropriate temperature and humidity control, to create a精品 tree-shaped茉莉 with sturdy branches and abundant flowers and leaves.
