We have a large pond surrounded by scrub, autumn olives, cattails, elderberry, a few trees, and large grasses (they look similar to bamboo). What I thought was algae may be duckweed, and it covers most of the surface each summer. How do I remove the autumn olives and cut back some of the growth so we can walk to the edge of the pond? I don't want stumps left everywhere and the ground is very marshy. What tools would we use? Also, we don't want to use chemical treatments, can we effectively rid the pond of duckweed manually, or is it too invasive? We'd like a depth of maybe 10 feet of growth, with pond access points rather than 20 feet, around the perimeter.
