I found some fire color sprinkles which is basically powdered copper. Can anyone advise me on what ratio of powder to water to spray my tomato plants. Or if that is even a good idea?
Thanks Kindly

You mean pure copper metal in powered form? It won't dissolve in water and i don't think it would be healthy for your plants or soil anyway.

For garden use copper sulphate is what is usually used, it does dissolve in water. It's a bluish powder. Copper powder not good for garden.
