The only cattail that I would plant is the dwarf cattail that stays short. After years of experience with tree leaves in a pond I would not plant any trees near the pond. I have had tree roots grow 3 times further out beyond the branches drip edge. Roots can transpire a lot of water from the pond. Roots also infiltrate the pond wall eventually causing leakage. Only tree that I like near the pond is the arborvitae and white cedar. If you have to have trees stay with short varieties and keep them on the down wind side of the pond. Tree leaves are an enemy to the pond due to producing excess organic matter that results in excess bottom muck / slop.

Bill, why do you like White Cedar vs. other coniferous trees?
