Please help we live in a cute little bungalow, with a stone path that leads from our back deck to our patio and garden. The path has patio stones and gravel throughout it. It looks great but when the weeds take over it looks horrible and pulling weeds is very time consuming. The people who put the path in, placed plastic over top of the earth, then gravel and just placed the stones in whatever way because they are easy to move. How can we fix the weed and stone problems without having to tear the path out and start again?
