Why block paving and gravel are such weed magnets, and how to clear them and keep them out: re-sanding, sealing and gravel membranes.
Do weed membranes actually work?
Yes for a while, no forever: what a membrane genuinely stops, why it fails over time, and the research that says mulch alone can do the same job.

What the residual half of a path and drive weedkiller actually does in a paving joint, how long it really lasts, what it costs per square metre, and the surface it is not approved for.
