ML ,DD and GG :

As Bill often reminds us , it all depends. We have 2 ponds within 500 yards of each other. Same type of soil and landscape both 25 yrs. + and same mgt. plan. One has had weed problems FA, pondweed, cattails, waterleaf, water primrose ,and others. The other has none of that and a GC would have starved. No weed problems in its 50 yr. history. Go figure? ewest
