Jasmine flowering season
As a representative of traditional Chinese fragrant flower plants, jasmine is deeply loved for its simple and elegant fragrance. Its flowering characteristics are closely related to maintenance methods, and mastering the correct approach allows the pure white flowers to bloom from early summer to late autumn.
Characteristics of Jasmine Flowering Time
Natural Flowering Span
In its natural state, jasmine flowers mainly bloom from May to August, and the flowering period can be extended to November through artificial intervention. The lifespan of a single flower is about 1-2 days, but the inflorescence continuously differentiates new buds, creating a wave-like blooming effect.
Influence of Temperature and Light
When the average daily temperature is stable above 20°C, the flower buds begin to differentiate, and the flowers bloom most vigorously around 30°C. It is necessary to ensure more than 6 hours of direct sunlight each day, making a south-facing balcony or open courtyard the most suitable for cultivation.
Annual Three-Season Flowering Cycle
First Flush Flower Management
The first batch of flower buds appearing in early June are recommended to be removed, as they are few and consume the plant's stored nutrients. Retain 2 pairs of leaves for branch pruning to promote the germination of lateral branches for subsequent flowering.
Summer Flower Care
In the full bloom period of August, phosphorus and potassium fertilizer should be supplemented every 3 days, with a 0.2% phosphorus acid hydrogen potassium solution foliar spray showing significant results. Appropriate shading at noon and maintaining air humidity above 60% can extend the lifespan of a single flower.
Autumn Flower Regulation
In late September, reduce nitrogen fertilizer (N) and gradually decrease the watering frequency. Move the plant indoors when the night temperature is below 15°C, use supplementary lights to maintain daily sunlight duration, and the flowers can be prolonged until the frost.
Key Maintenance Techniques
Substrate Formula Improvement
Use a mixed substrate of humus soil: coarse coconut bran: perlite = 5:3:2, changing the potting soil every two years. Regularly add decomposed sheep manure to improve soil structure, maintaining a pH value of 6.0-6.5 in a slightly acidic environment.
Water and Fertilizer Management
Keep the soil moist during the growing season but avoid waterlogging, using the immersion pot method for more even watering. Apply bone meal before flowering to supplement calcium, combined with EM bacteria solution for root irrigation to enhance nutrient absorption efficiency.
Overwintering Protection Measures
Keep the potting soil slightly dry during low temperatures and wrap the flower pot with double-layer thermal insulation film. Prune heavily in the spring when it warms up, retaining the main stem at 15-20cm to stimulate the germination of new branches.
By precisely controlling the light cycle and water and fertilizer supply, combined with scientific pruning techniques, jasmine can achieve continuous flowering throughout the year. Regularly observing the plant's condition and adjusting the maintenance plan in a timely manner allows the fragrant white flowers to decorate the living space year after year.
