Holes in crocus buds/flowers?
I am in zone 7b in about central NC. My crocus buds and flowers have huge holes in them. Any ideas?
-- They were originally planted fall 2011 and came up beautifully in 2012.
--They are in a full sun box.
--I made sure to not cut/remove leaves until they were good and brown.
--I did use leaf mulch this winter (but not the first one).
--I didn't fertilize until a few weeks ago (would earlier have helped)?
--Our winters are usually 40s and 50s with some 30s. It did seem wetter this past winter.
