BARLEY SEED FOR GROWING BARLEY
STRAW FOR USE AS A NATURAL ALGAECIDE IN PONDS AND FOUNTAINS
Barley straw controls the growth of algae in ponds and
fountains. When the barley straw is placed in ponds, it
begins to decompose and releases lignins into the water.
The lignins are then oxidized into humic acids, which in
turn, produce hydrogen peroxide. The continuous release
of hydrogen peroxide stops algae from reproducing and stops
growth of existing algae.
Depending on pond size, the straw can be used in bales,
sprinkled in water as loose straw or conveniently packed
into net bags. The amount of straw needed depends on the
surface area of the pond. Approximately 1/3 ounce of straw
per square yard of surface area is recommended. More may
be used at first if water is already green and decreased
once the algae is under control. Time needed to get algae
under control depends on amount of algae already present
in water and water temperature.
Barley straw is harmless to plants, fish, pets and wildlife.
