  • Copper sulfate is (was) one of the ingredients of the styptic powder, Kwik Stop, which is/was widely used to stop superficial bleeding in animals.
  • Copper sulfate can be applied to your plants before the disease starts as a preventative as well as when you begin to notice the dark spots of infection show.
  • As an additive to swimming pools to clear the water and eliminate algae. Put half a teaspoon every 10 to 15 days into the skimmer box and let the pool pump run for at least 12 hours. (You can swim right away)
  • Copper sulfate pentahydrate is a fungicide. However, some fungi are capable of adapting to elevated levels of copper ions. Mixed with lime it is called Bordeaux mixture and used to control fungus on grapes, melons, and other berries.
  • Bluestone is frequently encountered as an ingredient in mojo hands made by African-American hoodoo doctors, especially those for gamblers' luck and protection from evil. It is sometimes mentioned in old recipes for floor wash used by spiritualists to purify the home in the interest of keeping out evil spirits.
  • Copper sulfate has had widespread use over the years to control roots in sewer lines. Although most plants need a small amount of copper to survive, a high concentration of the metal can injure the roots without actually killing the plants. Introducing copper sulfate into the sewer line is an effective and easy way to increase the concentration of copper in the sewer water and kill the roots. The usual method is to pour 1 or 2 lbs. of crystals into the toilet nearest the sewer line, then flush the toilet.
