How to Manage the Blooming Period of茉莉花 (Jasmine)
As the leader among the three fragrant flowers in the courtyard,茉莉花 (Jasmine) is deeply favored by gardening enthusiasts for its elegant fragrance and pure white blossoms. To make茉莉花 (Jasmine) bloom with the plumpest buds, mastering scientific blooming period management methods is crucial. This article will comprehensively analyze maintenance secrets from lighting, watering, and fertilizing to pruning, helping you create a jasmine-filled courtyard filled with fragrance.
Four Key Points for Maintaining茉莉花 (Jasmine) During Blooming Period
Light Control Strategies
茉莉花 (Jasmine) is a typical light-dependent plant, and 6 hours of direct sunlight per day can increase the efficiency of bud differentiation by 40%. Full-sun maintenance can be done in spring and autumn, while a shading net needs to be set up from 11:00 to 15:00 in summer to avoid leaf damage from high temperatures above 35°C. In winter, ensure 4 hours of sunlight on a south-facing windowsill each day, and using a grow light can extend the blooming period by 15 days.
Smart Watering System
Adopt the 'water when dry' principle, watering thoroughly when the top 3cm of soil is dry. It is recommended to set up a humidity monitor during the blooming period to maintain air humidity between 60%-70%. Water twice a day, morning and evening, during the hot season using rainwater or tap water that has been standing for 24 hours, to avoid directly rinsing the flower buds. Timely drainage is needed during the rainy season, as standing water for over 2 hours can cause root rot.
Nutrition Supply Plan
Alternate weekly between using phosphorus-potassium fertilizer (diluted 1000 times) and ripe rice washing water, and add bone meal during the full blooming period to supplement calcium. Spraying 0.2% phosphorus acid potassium solution on the leaves and combining it with EM bacteria solution for root irrigation can extend the blooming period of a single flower by 3-5 days. Be sure to rinse the leaves with clean water after fertilizing to prevent spot formation from fertilizer burn.
Accurate Pruning Techniques
Immediately after flowering, cut off 2 pairs of leaves below the残花 (spent flowers), leaving 1-2 buds at the base. Perform light pinching once a month to promote the growth of lateral branches. For branches over 3 years old, implement reduction pruning, leaving a 15cm trunk. Pruning tools need to be disinfected with alcohol, and the cut surfaces should be coated with a healing agent to prevent infection.
Detailed Explanation of茉莉花 (Jasmine) Blooming Cycle
In the Yangtze River Valley,茉莉花 (Jasmine) exhibits a 'three-season blooming' characteristic: flower buds appear in early May, reach full bloom from July to August (with a single plant producing 200-300 flowers), and the late blooming period is from September to October. Year-round blooming can be achieved through greenhouse regulation, and a day-night temperature difference of 8-10°C can increase the blooming frequency by 30%. The best time for picking flowers is from 5-8 a.m., when the essential oil content is highest.
By following the six-character principle of 'adequate light, moist, fertilized, and pruned', and precise management according to the phenological period, even beginners can make茉莉花 (Jasmine) bloom abundantly every year. It is recommended to establish a maintenance log, recording each pruning and fertilizing data, gradually forming a personalized care system, allowing this 'first fragrance in the world' to always stay in your home.
