Q.making peace lily fuller
My Peace Lily wasn’t split into two separate plants, so now I have the smaller one of the two. How do I get this small potted Peace Lily that wasn’t cut properly in half from the root bound Peace Lily that came from my Mother’s? How can I get it to start growing fuller? Do I need to give it a dose of fertilizer? It’s growing new stalks. But since it wasn’t cut properly, it is growing very, very slow. And it’s not bushing Up. After I’ve had it planted into a small flower vase for the tight compacted, like it prefers. What else can I do?
