We purchased an old Bed & Bath and have encountered a problem with the gravel drive. Weeds are sprouting throughout the very large driveway/parking area leading up to the house which is lined with gravel. After various attempts at spraying the weeds with chemicals they still keep coming back. The drive is also several hundred square feet so spraying constantly gets to be very expensive and time consuming. We know paving the drive would solve our problems but we prefer the gravel. It’s a medium size gravel right now, would finer gravel help? Do we need to line the base of the drive with something like weedblock that is used in gardens or would that make the gravel slip around all over when cars drove over it?
