Rinse “New” Plants First Before “Introducing” Them to Your Pond.
This is a common “rookie mistake” among new pond owners. Newly-purchased (or newly-obtained) aquatic plants should first be rinsed thoroughly. This precautionary measure helps circumvent the presence of any parasites or the growth of duckweed in your pond. “New” water plants can also be disinfected with some salts or Potassium Permanganate, to be added to a container of water where you “soaked” your new plants.
