Pond Boss Forums AQUATIC VEGETATION Balance of plants in the environment Hardy Water lilies gone wild?? Help

I think part of you problem is lack of regular division, thinning (maintenance), and possibly overcrowding and lack of space - too many in too small of space. It sort of sounds to me like they became similar to a pot bound lily or plant. I would do some divisions and repotting of your better varieties. Remove all others and sort of start over with new divisions.

I think hornwort and lilies will compete to some degree for nutrients and the lilies may need some annual pot specific fertilization to get optimum blooming.
