I was at the nursery the other day and was recommended to use a product called Protekt (with a K) from a company called Dyna-Gro. It is a fertilizer nutritional supplement that is supposed to add silicon to the plant or tree foliage to help it against the harsh elements of sun, wind, etc... Has anyone ever used it? Any reults? ANy helpful hints on how to use the product effectively? Any other thoughts?
