Q: I have seen golf courses use green sand to fill divot holes on their course. How can I make green sand to cosmetically hide small problem areas in my lawn until the grass takes over the spot?
A: I think you’re seeing a divot repair mix that has been dyed green. Most courses keep a container on the carts or near each green so golfers can repair damage done during a shot. I don’t know how the coloring is done commercially but you could experiment with food coloring or perhaps concrete dye. A better option would be to use one of the lawn patching products that contains seed and a green mulch material.
