I have a patio, that is laid with natural stones,with moss growing between the stones. I thought it was very pretty when we purchased this home, but now the moss has turned into grass and weeds, and as we are in our 60's the stone are a little uneven, and it is even hard to sit our patio furniture, especiall the table, on these stones, and maintain an steady table and or seating. Otherwise, we have a lovely backyard, with a fountain, two huge trees, and lots, of hostas, flowering bushes, etc. We do not have the extra money it would take to remove the stones, and do some type of patio. I wonder if you have any suggestions.
