Had many oriental, aisatic and calla lilies that have great leaves, but alas, no blossoms. Could they bloom next year if treated correctly. In other words, should I use something now? Like bonemeal, or fish emulsion, etc. Or is it better to yank them out? Tha is, Nancy

The lack of blooming in most lily species is due to one or two reasons:
1). A lack of sufficient light
2). Crowded conditions; consider dividing your lilies this fall.
If these plants have bloomed in past years, my best guess is the latter
Overall I would guess that your plants are just fine. Applying a fertilizer rich in phosphorous, such as bone meal, would not hurt.
