Some creative PB Forum member should test this bottom sheet plant inhibiting idea. What I know is it did not work for me. I think it is even less likely to inhibit coontail that is classified as a non-rooted plant and can thrive without true normal root structure.

This type of weed control / management is discussed in a book titled "Lake Smarts The First Lake Maintenance Handbook" and 2nd edition Lake and Pond Management Guidebook. both by Steve McComas. He says the preferred and tested method is to use a woven fiberglass screen product. It can get gas bubbles under the barrier plus it has other concerns and limits. It is recommended to lift and clean the barrier each year. If the barrier is left in place sediment collects on top of it and new plant material eventually becomes established.
