Algae & Weed Control
(3 Common Types)
Filamentous algaeis most common, growing in mats and strings.
Planktonic algaecauses green water, it has millions of cells that cloud together.
Chara algaeis weed-like, it grows like a carpet along the bottom.
Cattails & Other Emergent Plants- Emergent plants grow around the perimeter of a pond in shallow water with all or most of their foliage above water. Examples are Cattails, Bulrush, Reeds, Purple Loose Strife, Pennywart and Pickeralwood.
Pondweeds- The pondweed family has over a dozen varieties with these four being the most common: Sago, Clasping Leaf, Curly Leaf, Large Leaf.
Elodea- This plant grows in thick clumps and is usually not a big problem, the leaves are in whorls of three around the stem.
Duckweed & Watermeal- Duckweed is hard to control, it forms a thin layer over the surface in calm ponds. It will not grow well in moving water so use of a surface aerator will help in controlling growth.
Waterlilies- Waterlilies can become a problem in many ponds, they grow off of a large central root system (much like popal trees). Some growth is great for shade and cover for fish, but when left unchecked they will overpopulate quickly.
Eurasian Milfoil- Spreads very easy since fragments of plant can re-root and grow. Do not try to remove by raking.
Other Less Common Weeds: Include Naiad, Coontail, Bladderwort, Hyrdilla, Parrot Feather & Water Hyacinth.
