When does the Osmanthus Flower Bloom
As a classic representative of traditional Chinese courtyard flowers, the osmanthus flower is deeply loved by gardening enthusiasts for its waterfall-like bloom quantity and elegant fragrance. Its unique blooming characteristics and key points of maintenance are essential in creating a spring flower corridor.
Analysis of Osmanthus Flower Blooming Period
Standard Blooming Period
The osmanthus flower blooms mainly from April to May, with a single flower's blooming period lasting about 7-10 days, and the group blooming period lasting about 20 days. Through precise temperature control technology, Jiangsu Shuyang Changjing Garden can make some early blooming varieties bloom as early as late March.
Varietal Differences
Double-petal osmanthus flowers bloom 5-7 days later than single-petal varieties but extend the viewing period by 3-5 days. The phenological difference between yellow osmanthus and white osmanthus is within 2-3 days, and mixed planting can extend the overall viewing period.
Complete Guide to Osmanthus Flower Maintenance
Water Control Strategy
During the blooming period, it is necessary to maintain soil moisture at 60-70%, using immersive irrigation methods. It is recommended to set up an automatic drip irrigation system, supplementing water twice a day, with each watering volume controlled at 500-800ml/m².
Nutrition Supply Plan
Apply compound phosphorus-potassium fertilizer (N-P-K=5-10-10) 30 days before blooming, at a rate of 200g per square meter. During the bud formation stage, apply boron fertilizer solution (0.2% concentration) and spray twice on the leaves at 10-day intervals.
Light Control Key Points
Ensure at least 6 hours of direct sunlight per day, and use a 50% shade net during the strong sunlight period at noon. When planting on the north side, it is recommended to set up reflector boards to enhance the light intensity for lower flower buds.
Disease and Pest Defense System
During the blooming period, focus on preventing aphids and black spot disease. It is recommended to alternately spray matrine (diluted 1000 times) and mancozeb (diluted 800 times) once a week for preventive treatment.
Through scientific maintenance management, the osmanthus flower can not only achieve the expected blooming period but also present a magnificent display like clouds and rosy. It is recommended to visit professional nurseries such as Changjing Garden to purchase quality seedlings and obtain customized maintenance plans.
