How to Care for Narcissus
As one of China's top ten traditional famous flowers, narcissus is deeply loved by people for its elegant and unconventional form, as well as its fragrant and rich characteristics. Whether grown in soil or water, mastering scientific care methods can make narcissus bloom more beautifully. This article will provide a detailed analysis of the full cycle care points for narcissus, from substrate selection to flowering period management.
Scientific Narcissus Care System
Substrate Configuration and Cultivation Choices
The narcissus has unique requirements for the cultivation substrate: 1. For soil cultivation, it is recommended to use humus soil + river sand + perlite (proportion 5:3:2) to ensure a balance of loose and breathable properties with water retention. 2. For water cultivation, a special planting basket should be chosen to secure the bulb with cobblestones, and the water level should be maintained 1 cm below the root disk. 3. The substrate pH should be controlled between 6.0-7.0, which can be adjusted by adding rice husk charcoal.
Critical Period for Nutrient Supply
Narcissus nutrient management is divided into three stages: • Growth period: Apply diluted organic liquid fertilizer (recommend earthworm fertilizer or soybean cake fertilizer) every two weeks. • Bud formation period: Switch to phosphorus-potassium fertilizer (monopotassium phosphate 1500 times liquid foliar application), supplemented with weekly sugar alcohol calcium supplementation. • Flowering period: Stop fertilizing to avoid premature flower wilting.
Intelligent Watering System
Watering strategy needs to be adjusted according to the growth stage: 1. Keep the substrate moist (water content 60-70%) during the germination period. 2. Increase water supply (water content 80%) during the stem elongation period. 3. Gradually reduce water supply after flowering, and change the water daily for water cultivation to prevent root rot.
Comprehensive Pest and Disease Control Plan
Implement precise prevention and control measures for common issues: • Bulb rot disease: Use carbendazim 800 times liquid to water the roots at the early stage of the disease, combined with the removal of decayed tissue. • Leaf spot disease: Spray with mancozeb zinc 600 times liquid and maintain environmental ventilation. • Root mite control: Use matrine biological insecticide, combined with high-temperature disinfection of the substrate. • Preventive measures: Spray the leaves with garlic extract (1:10) monthly to enhance disease resistance.
Through scientific temperature control (optimal growth temperature 12-18℃), light management (4-6 hours of scattered light daily), and post-flowering treatment (retain leaves to wither naturally), the rejuvenation cultivation of narcissus can be achieved. It is recommended to change the cultivation method for water-grown plants every year and divide and change the soil for soil-grown plants every two years. By following these care rules, your narcissus will surely bloom with a frosty and jade-like elegance year after year.
