Odd that you have some spots that are so "resistant" to repeated sowing of seeds even though other parts seem to be doing pretty well. If your friend is a landscaper I'm sure he knows what he's talking about, but I'm surprised by the recommendation to use sand. Sand doesn't retain water - it just drains through. I'm a big believer in compost. It retains moisture and provides nutrients for the plants.
