Things You'll Need
- Rope
- Mesh bag
- Water lilies
- Heavy rock
- 2 handfuls of barley straw
Instructions
Tie the handfuls of barley straw together over the rock so that it is one bundle and place the bundle in the mesh bag.
Submerge the bagged bundle of barley at the center of the pond. Barley straw, when it decomposes, releases chemicals that prevent the growth of algae.
Cover the pond with water lilies, covering about two-thirds of the surface area. The lilies will block out sunlight and absorb algae-promoting nutrients.
