Why won’t my daylilies bloom?

Many factors may lead to an individual daylily plant not blooming. Some of the most common causes include: 

• Lack of sufficient sunlight. At least five hours per day is recommended. 
• Overcrowding. A previously floriferous clump no longer blooming is a sure sign that the clump is in need of division. 
• Immature plant. Smaller daylily divisions may take a year to fully establish before blooming
