What to Do If Lily Flowers Don't Bloom
Lilies are favored by gardening enthusiasts for their elegant floral posture, but they often face the problem of not blooming during maintenance. This article deeply analyzes the three key causes based on the growth characteristics of lilies and provides operational solutions to help you restore their fragrant blooms.
One: Bulb Quality Determines Bloom Quality
1.1 Analysis of Aging Bulbs Impact
Budget bulbs sold in the market are often aged bulbs from a 3-4 year production cycle, with insufficient nutrient storage leading to hindered flower bud differentiation. Experimental data shows that bulbs with a diameter < 14cm have a blooming rate of only 32%.
1.2 Guide to Choosing Imported Bulbs
It is recommended to choose high-quality bulbs imported from the Netherlands with a circumference of 16cm+, plump scales that are milky white, and bulbs weighing >80g, which can achieve a blooming rate of 91%. It is suggested to combine perlite and peat soil (1:3) as a substrate to enhance root development efficiency.
Two: Key Points of Light Control Technology
2.1 Golden Hours of Photosynthesis
Ensure a light intensity of over 20000Lux from 9:00 to 11:00 daily, which can be monitored with a professional light meter. A south-east facing windowsill or an outdoor environment with a 30% shading rate is ideal.
2.2 Application Scheme of Supplemental Lighting Equipment
During rainy seasons, it is recommended to use full-spectrum plant lights, providing supplemental lighting for 4 hours daily at a distance of 50cm from the plant. LED light wavelengths should include a combination of 660nm red light and 450nm blue light to promote anthocyanin synthesis.
Three: Detailed Management During Bud Stage
3.1 Optimization of Nutrient Ratio
Apply N-P-K=5-10-10 water-soluble fertilizer during the budding stage, once a week diluted 1000 times for root irrigation. Combined with 0.2% phosphorus acid monopotassium spray on the leaves, it can increase the number of flower buds by 23%.
3.2 Standard for Transportation Protection
Use EPE pearl cotton layered packaging, maintaining a temperature of 15-18°C and humidity of 60%RH. It is recommended to choose a constant-temperature logistics box for transportation to avoid flower bud drop caused by day-night temperature differences >8°C.
Through systematic management of bulb selection, light environment control, and precise flowering care, combined with the use of professional gardening tools, the reblooming rate of lilies can reach over 98%. It is recommended to establish a maintenance log, recording data such as temperature and light, to gradually form a personalized maintenance plan.
