What Causes the Excessive Growth of Jasmine Branches?
Jasmine branches growing excessively is a common issue in the maintenance process, which not only affects the aesthetic appearance of the plant but may also delay flowering or even prevent flowering altogether. When slender branches grow rampantly, it often indicates that the plant's growth needs are not being met. Observing the growth state of the branches can help us adjust the maintenance strategy in a timely manner.
Key Elements of Branch Management
Pruning Timing During Dormancy
Pruning after flowering should be completed within 10 days, retaining 3-4 bud points on the main branches. In winter, heavy pruning should leave the main trunk about 15cm long, and combined with potting and root pruning, it can stimulate the development of new roots. Formative pruning should be done before spring sprouting, removing intersecting and parallel branches to improve ventilation.
Regulating Light Intensity
In spring and autumn, ensure 6 hours of direct sunlight, avoid strong midday light in summer. Use supplemental lights in winter for 2-3 hours a day, controlling light intensity between 5000-8000 lux. For north-facing balconies, it is recommended to set up reflective boards to increase the utilization of diffused light.
Optimization of Growing Environment
Control of Nutrient Ratio
Use a 10-30-20 nitrogen-phosphorus-potassium water-soluble fertilizer during the growing period, and apply additional potassium dihydrogen phosphate during the budding period. Replace the potting soil every 2 years, with the matrix formulated as garden soil: decomposed leaf soil: river sand = 4:4:2, adding bone meal as a base fertilizer.
Temperature and Humidity Management
Maintaining a day-night temperature difference of 8-10°C can inhibit excessive growth, and the night temperature should not exceed 18°C. Keep the air humidity between 60-70%, adjust using a wet gravel tray method, and avoid direct spraying on the leaves.
Key Points of Maintenance During Special Seasons
During the plum rain season, set up a rain shelter, and stop fertilizing and reduce watering during continuous rainy days. Water twice a day in the high-temperature summer period, using the immersion pot method to ensure deep soil moisture. Reduce watering frequency after bringing the plant indoors in winter, keeping the soil slightly dry.
By combining阶段性 pruning with environmental control, the jasmine can maintain a compact plant shape. It is recommended to establish a maintenance log to record pruning times, fertilization cycles, and other data, and adjust the management plan dynamically based on the plant's response. Regularly rotating the pot direction can promote even light exposure to the branches and prevent biased growth.
