Today I transplanted those fern to the growbed on top the brick wall. I took only those older fern rhizome and trim all the leaves and plant it.
It will takes sometime for it to colonize this grow bed, and give my backyard a natural curtain for privacy.
This fern was such a bush as previous post, I am worried with those bigger fern trimmed water quality may be compromise. These fern provide good water cleaning properties. I have too see what effect it have to my tank water.
