Beginner Gardening: Pond Iris Biomass, 1 by HollyAnnS

The plants in this pond grow like crazy thanks to the nutrients deposited by the birds. My husband uses the roots from the iris to help keep the pond clear and clean. Every spring he divides the iris and instead of potting it he ties a small piece of it to a blue milk crate. And weights it down with a rock.
At the end of the season it takes both him and my very strong son to get it out of the pond. The crate is completely filled with roots and the mass is just unbelievable.
