What to Do When Aquatic Lily Fails to Bloom
Aquatic lilies are loved for their clean and elegant characteristics, but many enthusiasts often face the issue of their lilies only growing leaves and not blooming. This article will systematically analyze the key care points for blooming aquatic lilies from four core dimensions: water level control, water quality management, pruning techniques, and nutritional supplementation.
Water Level Control and Water Quality Management
Scientific Adjustment of Water Level Height
When the water level in the hydroponic container exceeds 1/3 of the stem, it can cause root hypoxia and asphyxiation. It is recommended to maintain a water level of 2-3 centimeters, and by regularly observing and replenishing water, it can ensure water absorption needs and promote bud differentiation.
Establish a Regular Water Change Schedule
In spring and autumn, change the water every 3 days, in the high summer temperatures, change the water every 48 hours, and in winter, extend it to changing the water every 7 days. When changing the water, retain 1/3 of the old water to maintain microbial balance, and clean the mucus substances from the inside walls of the container.
Plant Pruning and Nutritional Enhancement
45° Diagonal Cutting Technique
Use a sterilized scissor to perform a 45° diagonal cut every 3 days, moving the cut 1-2 centimeters upwards, effectively increasing the water absorption area by more than 30%. After pruning, use a cotton cloth to absorb the secretion from the cut before placing it back into the container.
Scientific Nutrient Solution Ratio
Add a specialized hydroponic nutrient solution when changing the water, diluted at a ratio of 1:500. During the budding stage, apply phosphorus and potassium fertilizers, and supplement with iron sulfate solution twice a month to prevent yellowing leaves, ensuring the nutritional supply for bud development.
By controlling the water depth, maintaining clean water quality, regularly pruning the stems, and properly supplementing nutrition, these four measures work together. Combined with an ambient temperature of 18-25°C and 4 hours of scattered light daily, it is usually possible to observe the bud expansion phenomenon within 2-3 weeks. It is recommended to use a transparent container simultaneously to easily observe the root status and adjust the care plan in a timely manner.
