Pocket BotanistCheck these first
- Count the hours of direct sunlight your plant receives each day.
- Inspect the base of the plant to see if the clump has become extremely tight and crowded.
- Check if you have been using a high nitrogen fertilizer which encourages leaves instead of flowers.
Likely causes
Insufficient Sunlight
Most likelyHow to tell: The foliage looks healthy and green, but no flower stalks appear. The plant is likely in a spot that gets less than 6 hours of direct sun.
What to do: Move the daylily to a location that receives at least 6 to 8 hours of direct sunlight daily. If moving is not possible, prune back overhanging tree branches to increase light exposure.
Overcrowding
PossibleHow to tell: The clump has grown very large and dense over several years. The center of the plant may look sparse or woody.
What to do: Dig up the clump in early spring or fall. Divide the root mass into smaller sections with a sharp spade and replant them with enough space to grow.

When to worry
It is normal for newly planted daylilies to skip blooming for their first year while they establish roots. Worry if an established plant fails to bloom for two consecutive seasons.
Stopping it coming back
Divide your daylilies every 3 to 5 years to keep them vigorous and ensure they have enough room to produce flower buds.

Questions people ask
- Will shade cloth help my daylilies bloom?
- No, shade cloth will likely make the problem worse. Daylilies need plenty of sun to store the energy required for flower production.
- Does fertilizer help?
- A balanced fertilizer applied in early spring can help, but avoid high nitrogen formulas that just make the leaves grow.
