How to Care for Hyacinth During Bloom
As one of the most popular bulb flowers in early spring, hyacinths are favored for their unique spike-like inflorescence and fragrant aroma. Mastering the tricks of bloom care and flowering time adjustment is particularly important to achieve a spectacular display. This article will systematically analyze the key technologies for extending the viewing period, from light management to temperature control.
Elaborate Care Plan for Hyacinth During Bloom
1. Stabilize the Environment to Avoid Displacement
When the first flower bud opens, it is necessary to fix the position of the potted plant. Sudden changes in the environment can cause the flower stem to twist, resulting in the shedding of over 30% of the buds. It is recommended to choose a window area with good ventilation and stable temperature and humidity.
2. Scientific Light Control
Maintain 4-6 hours of diffused light daily, using a shade cloth with 40% light transmission to filter strong light. The light intensity should be controlled between 10,000-15,000 lux, which can be monitored with a professional light meter. Overexposure to sunlight can shorten the bloom time of a single flower by 2-3 days.
3. Precise Water and Fertilizer Management
Apply a phosphorus and potassium solution (0.2% concentration) every 10 days during the bud formation stage, and stop applying nitrogen fertilizer during the full bloom stage. Use the "moist when dry" watering method, maintaining a substrate moisture level of 60%-70%. Over-wetting can cause bulb rot.
Factors Influencing Hyacinth Bloom Time
1. Regional Climate Differences
The natural blooming period shows distinct latitudinal characteristics: the Lingnan region blooms in early March, the Yangtze River Valley in mid-February, and the northern heating areas can achieve blooming during the Spring Festival through temperature control. A day-night temperature difference of 8-10°C is most conducive to bud differentiation.
2. Spring Control of Bulbs
Commercial bulbs require 6-8 weeks of low-temperature treatment at 2-5°C. Unvernalized bulbs have a reduced flowering rate of 40% and the flower spike is shortened by 1/3. For home cultivation, wrap the bulbs in newspaper and place them in the refrigerator fruit and vegetable compartment to complete the vernalization process.
Through scientific environmental control and precise care, the viewing period of hyacinths can be extended to 20-25 days. It is recommended to cut off the withered flowers and retain the leaves after blooming, then remove the bulbs for sand storage after natural withering, to store energy for the next year's reblooming.
