What season does the narcissus bloom?
As a representative of Chinese traditional New Year's flowers, narcissus is loved for its simple and elegant fragrance. Every time the Spring Festival comes, placing a pot of blooming narcissus on the table always brings a burst of spring. However, many flower friends are often confused: why doesn't the flower bloom even after careful care? In fact, mastering its growth patterns and blooming tips can make the narcissus bloom on time.
Characteristics of the Growth Cycle of Narcissus
Biological Characteristics of Autumn Planting and Winter Blooming
Narcissus belongs to the typical autumn-planted bulbous flowers, with bulbs waking up and rooting from September to November, and starting to sprout in December. The flower bud differentiation requires a low-temperature stimulation of 10-15℃, so the natural blooming period is concentrated in January and February, with some late-blooming varieties lasting until early March.
Environmental Impact on Blooming Period
Temperature is the key factor in regulating the blooming period, with the fastest growth rate in an environment of 15-20℃. In the southern regions, when cultivated outdoors, the blooming period is often提前 due to higher winter temperatures; in the north, excessive heating indoors can lead to the phenomenon of flower buds withering.
Three-Stage Flower Boosting Care Method
Temperature Control Strategy
When the flower bud forms but stops growing, the gradient warming method can be used: 1. Maintain 18-22℃ during the day and not lower than 12℃ at night. 2. Use a transparent cover to create a greenhouse effect. 3. Avoid direct blowing of air conditioners or baking by radiators.
Light Enhancement Plan
Ensure 6 hours of direct sunlight every day: • Use plant growth lights to extend the lighting time to 10 hours • Regularly rotate the flower pot to ensure even light exposure • On cloudy and rainy days, use a mirror to reflect and enhance brightness.
Optimization of Hydroponic System
The water temperature should maintain a ±3℃ difference from the room temperature: • Change the 25℃ warm water daily • Add 2 drops of plant vitality • Control the water level at 1/3 of the bulb • Use a black container to promote root development.
Secrets to Extend the Viewing Period
After the first flower opens, the cooling method can be adopted to reduce the ambient temperature to 10-12℃, and by adding 5% sugar water every 3 days, the overall blooming period can be extended by 7-10 days. After the flowers fade, promptly remove the withered flowers and retain the leaves to continue photosynthesis, accumulating nutrients for the next year's reblooming.
