Abstract: An aquatic weeder is provided which includes an elongated handle with a generally rectangular, flat blade assembly rigidly mounted at the lower end thereof. The weeder includes a pair of support straps extending from the handle to each end of the blade assembly. The blade assembly includes a flat rectangular cutting blade sandwiched between a pair of rigid generally rectangular support plates. The aquatic weeder is useful for cutting and pulling weed growth from the underwater soil surface just above the root tops to leave the underwater area growth free.
