Pond Boss Forums GENERAL QUESTIONS Property Projects & Construction Are wood chip mulch harmful on a steep pond bank?

+1 on the stone. Two layers of 4" plus rock cover will reduce the plant growth and make spraying with weed killer much easier and cost effective (once you get over the cost of the rock). I also like the idea of killing off the slope and getting a more desired plant to take over, but you will likely continue to fight the tree saplings unless your plant of choice is thick and tall (like 3 or 4 feet tall).

I'm afraid that mulch would end up washing into the pond under heavy down pours and it only takes a couple of years before mulch breaks down an turns into some fantastic top soil for more plants to grow, not to mention the nutrient load it would add to the BOW.
