How to Make African茉莉 Bloom
As a tropical evergreen shrub, African Jasmine is favored for its pure white and fragrant flowers. Many flower enthusiasts often face the dilemma of vigorous plant growth without blooming. Actually, by mastering four core maintenance points, you can make your African Jasmine bloom as expected, filling the room with fragrance.
Light Management and Temperature Control
Light Intensity and Duration Requirements
African Jasmine is a positive plant, requiring 4-6 hours of direct sunlight daily. It is recommended to provide full sun in spring and autumn, shade 40% from 10-15 hours in summer, and place it on a south-facing windowsill in winter. Experimental data shows that when the light intensity reaches 20000-30000 lux, the efficiency of flower bud differentiation increases by 60%.
Temperature Gradient Control
Maintaining a day-night temperature difference of 8-10°C is most conducive to flower bud formation. A daily temperature of 25-30°C and a night temperature of 18-22°C are the best ranges. When the temperature exceeds 35°C, a spray cooling system should be used, combined with an air flow of 0.5m/s per hour, which can effectively prevent high-temperature burns.
Nutrient Supply and Plant Management
Phosphorus and Potassium Fertilizer Ratio Plan
During the flower bud differentiation period, apply a water-soluble fertilizer with N-P-K=5-15-15, and spray 0.2% potassium dihydrogen phosphate solution on the leaves every 10 days. Special attention should be given to adding decomposed bone meal during the budding period, with 200g per square meter of soil increasing the number of flowers by 35%.
Scientific Pruning System
Use a three-level pruning method: level one removes sick and weak branches (retaining 3-4 main branches), level two shortens the overly long branches (retaining 3-4 nodes), and level three removes the terminal buds to promote lateral branches. Data shows that reasonable pruning can increase the number of flowers by 50% and extend the blooming period by 15 days.
Environmental Optimization and Special Treatments
Humidity Adjustment Techniques
Maintain an air humidity of 60-70%, using a pebble water tray combined with an ultrasonic humidifier, along with daily morning and evening foliar atomization. Be careful not to directly spray the flower buds during the blooming period to prevent mildew.
Root Care Essentials
Every two years, when repotting, use a growing medium mixture of red jade soil: decomposed leaf soil: perlite=5:3:2, and add 5% pine phosphate to improve aeration. Regularly check the EC value to keep it between 1.2-1.8mS/cm, with a pH value of 6.0-6.5 being optimal.
Through systematic light and temperature control, precise nutrient supply, and scientific plant management, combined with regular environmental monitoring and adjustments, African Jasmine can not only achieve stable blooming but also showcase its unique charm as a tropical flower. It is recommended to establish a maintenance log, recording daily environmental parameters and plant changes to gradually form an individualized cultivation plan.
