I finally asked my neighbor about his gravel path after seeing it hold up for 3 years
He lives two doors down in our Phoenix suburb, and his whole backyard is rock and cactus. I asked him last week what he used under the gravel to keep weeds out. He said, 'I just used the cheap landscape fabric from the big box store, but I put down a full 4-inch layer of crusher fines first and compacted it.' He explained that the fines make a solid base so the fabric doesn't tear, and the gravel on top stays level. His path looks as good as the day he put it in, with almost no weeds. Has anyone else had luck with crusher fines as a base layer, or did you use something different?
