Hand-pulling allows the flexibility to remove undesirable aquatic plants while leaving desirable plants. These methods are environmentally safe. Disadvantages As plants regrow or recolonize the cleared area from fragments, the treatment may need to be repeated several times each summer. Because these methods are labor intensive, they may not be practical for large areas or for thick weed beds. Even with the best containment efforts, it is difficult to collect all plant fragments.
Most aquatic plants can regrow from fragments.
Some plants, like water lilies which have massive rhizomes, are difficult to remove by hand pulling. Pulling weeds and raking stirs up the sediment and makes it difficult to see remaining plants. The V-shaped cutting tool is extremely sharp and must be only used with great care. Permits Permits are required for many types of projects in lakes and streams. Check with your city or county before proceeding with your project.
