I have a daylily border in my front flower bed, which has been there for about 3 maybe 4 years. The past several years we had blooms, not profuse, but definite blooms. This year, however, we have had zero. I'm pretty irritated about it. This border hasn't even filled in all the way yet, so I don't think being too full and needing dividing is the issue. (but I'm no expert here) Has anyone else experienced this, or know what the problem could be?
