I wonder though, if lily type has a lot to do with production? When I moved
my lilies from 6-8" from the surface down to 20" some (most) have performed
better, and others have not. Flowers seemed bigger.

I put in the lily pond because the koi pond was so shady, but now my
neighbor's trees (evergreen) have grown to the point of also causing a lot
shade there. Only way I can win is to move. :-( ~ jan
