What to Do When Narcissus Falls Over
Narcissus, as a traditional New Year's flower, often困扰s flower enthusiasts with its lodging issue. This article systematically analyzes five prevention and control strategies for phenomena such as the weak stems and drooping leaves of narcissus, helping you cultivate upright and graceful narcissus plants.
Causes and Solutions for Narcissus Lodging
Light Control Solution
Ensure 4-6 hours of scattered light every day, especially during the first 10-15 days of hydroponics, which is a critical period. Insufficient light can cause the leaves to grow at 2-3 times the normal growth rate. It is recommended to use a lux meter to monitor and maintain a range of 2000-3000 lux. In special cases, LED plant growth lights can be used for light cycle regulation.
Water Quality Management Tips
It is recommended to change the water every 72 hours, using tap water or purified water that has been standing for 24 hours. The addition of nutrient solution should follow the "Three-Stage Method": clear water maintenance during the rooting stage (first 7 days), adding 0.1% nitrogen fertilizer during the leaf extraction stage (7-15 days), and switching to phosphorus and potassium fertilizers during the budding stage (after 15 days). The temperature needs to be stable between 12-18°C, with a temperature fluctuation range not exceeding ±3°C.
Physical Support Techniques
Use the "Three-Pillar Positioning Method" to make a支架: insert 3 bamboo sticks in a triangular shape into the substrate and use green gardening ties to secure the stems at 3 nodes. For plants that have already fallen over, the gravity correction method can be used—hang a 5g weight at the tip of the leaves, continuing for 3-5 days to allow the stems to naturally return to an upright position.
Advanced Narcissus Care Techniques
Accurate Temperature Control
Scientific Pruning System
Establish a three-level pruning standard: level one pruning removes yellow leaves (retaining 100% healthy leaves), level two pruning controls leaf length (maintaining a standard of 25-35cm), and level three pruning adjusts the plant shape (keeping 5-7 functional leaves). After pruning, immediately treat the wounds with wood ash to reduce the risk of infection.
By implementing the above comprehensive prevention and control measures, combined with regular observation and recording, the incidence of narcissus lodging can be effectively reduced by more than 80%. It is recommended to establish a care log, recording key parameters such as temperature, light, and water change frequency, to achieve precise care and management.
