We live in Zone 6b. The year we planted the miniature daylilies they bloomed fine. No blooms since then and they are in the 3rd year. They get 6+ hours of sun and daily water via a drip system. Fertilizer was used this late spring in early June, since our temperatures were cool. They seem to be growing fine just no flowers. What can we do to get them to bloom? Bone Meal?
A soil test would tell you if you have excess nitrogen in the soil. Bone Meal is a good way to boost phosphorous; which should promote flowering.
Also after flowering it is a good idea to remove any seed pods that form. Leaving them on the plant can retard next years blooms.
