Thanks for asking.
The alternative is gravel with no weed f
proof underlay. The way I manage my gravel is to drop weed killer on selected wild plants such as docks, briars, holly , baby wild cherry ,and ivy. I positively encourage clover ,green alkanet, daisies , buttercups , dandelions, annual grasses , and garden escapes such as hyacinth. I think stinking iris is ugly so I ask a son to dig it up and bin it.
The large front drive which used to be a barley field has a lot of barley which is very pretty in spring and summer. The cars that park on my drive and front garden don't get bogged down in the wet as I just buy more river gravel as required.
