I'll have to take a picture tomorrow of mine. I put the taros in the rocks and nothing else, then have a catch pond that has some plants and I just cut that back this month...it really needed it.
Remember how small your taros were when I sent them to you? I had six of them left that were that small and now they're about 4 feet tall...so about 2.5 feet in a month and a half! I'll try to remember and post them tomorrow.
I had watercress in the waterfall years ago, but the roots from it changed everything and I had water running out onto the ground, so I plant nothing but taros in the falls now.
Just a reminder of what these taros do in a waterfall...the pictures below are dated: Four months of growth between first placing it in the water and the second picture
