Water hyacinth are one of the fastest growing plants known. They produce by runners which eventually form a new plant. In man made ponds they need to be thinned out periodically keeping them from covering much of the waters surface. When not controlled they can block sunlight from reaching other aquatic plants and starve the water of oxygen which can kill other plants and fish. Controlled they provide a food source for fish, keep the water clean and help to provide oxygen to ponds.
