Barley straw has been shown to emit a chemical that's effective in controlling algae in water gardens and ponds. There are many purely functional barley straw products on the market, but a new planter delivers the algicidal properties of barley straw in an ornamental package.
The Barley Straw Planter consists of a sturdy foam ring that contains the barley straw, and a hidden foam core that keeps the ring afloat. You can place terrestrial plants, such as houseplants or annual flowers, in the center of the donut hole and float the planter in your water garden. Plant roots are protected from nibbling fish by the foam core.
These planters come in three sizes: 3-inch, 9-inch, or 11-inch diameter rings. They treat ponds of 500 to 4,000 gallons. The planters keep the pond water clear for up to six months.
