When does the flowering period of Hyacinth start?
As a representative of spring bulbous flowers, Hyacinth is deeply loved for its brilliant colors and fragrant aroma. However, many flower enthusiasts often encounter problems such as abnormal flowering or failure to bloom during the maintenance process. This article systematically sorts out the key factors affecting Hyacinth flowering through detailed data and professional suggestions.
Characteristics and Patterns of Hyacinth Flowering Period
Natural Flowering Time Distribution
Under normal growth conditions, the peak flowering period of Hyacinth is concentrated in February to March. In the northern heating areas, flowering can be accelerated to late January due to the temperature advantage, the Yangtze River Valley often blooms in early March, and the southern regions may delay to late March due to insufficient low temperatures in winter.
Expression of Variety Differences
Early-flowering varieties like 'Pink Pearl' can bloom in 45 days at a temperature of 12°C, while late-flowering varieties like 'Blue Giant' require more than 60 days of accumulated temperature. Double-petal varieties have a flowering period about 5-7 days longer than single-petal varieties, but the difficulty of bud differentiation increases by 30%.
Key Inducements for Non-Flowering of Hyacinth
Imbalance of Light Energy
Daily sunlight less than 4 hours can lead to a 60% reduction in photosynthetic products, it is recommended to supplement with LED plant lights before the flowering period, maintaining 8 hours of 2000lux or more of sunlight daily. Complete darkness is required for storage during the summer dormancy period.
Mistakes in Temperature Control
Temperature higher than 20°C during the bud differentiation period can cause the phenomenon of flower bud abortion, the best day-night temperature difference during the bud formation period is 8-10°C (day 18°C/night 10°C). The water temperature should be kept stable at 15±2°C when hydroponic.
Improper Water and Fertilizer Management
Imbalance of nitrogen, phosphorus, and potassium ratios (recommended 1:2:2), EC value > 1.2mS/cm can inhibit flowering. Apply monopotassium phosphate (0.2% concentration) every 10 days before budding, stopping fertilization during the flowering period can extend the viewing period.
Plant Care Plan to Promote Flowering
Choose high-quality bulbs with a circumference >16cm, maintain a constant temperature of 9°C for 6 weeks during cold storage. The soil culture matrix should be mixed in the ratio of peat:perlite:vermiculite=5:3:2, maintaining a pH of 6.0-7.0. After flowering, cut off the残花 (withered flowers) and retain the leaves, then dig up the bulbs and dry them for storage after natural withering.
By precisely controlling the four elements of light, temperature, water, and fertilizer, combined with scientific bulb rejuvenation management, it is possible to achieve annual reblooming of Hyacinth, allowing the balcony to continue to bloom with rainbow-like flower spikes throughout the spring.
