Can wisteria be grown floating at the surface of an aquarium? I recently got two bunches of wisteria, and they were quite nice. I put them in my 2.8 WPG tank and rooted them, yet they are dying. Not the top, but near the end in the gravel , it's very mushy and brown. I guess they're not taking very well to the rooting. Can I float them instead? I think since all parts will be exposed to light, this might be a better way to grow them. Will floating wisteria thrive, or die?
