A membrane stops weeds from below. Most weeds in pebble beds arrive from above.

Where the weeds come from
A membrane blocks weeds rooted in the soil below. It does nothing about windblown seed landing on top of the stone and germinating in accumulated dust and organic debris — which is how most pebble-bed weeds start.
Depth helps
A 60–75 mm layer makes it much harder for a seedling to reach soil before it exhausts itself. Thin beds of 25–30 mm are the ones that need constant weeding.
The routine that works
- Rake the surface every few weeks to disturb seedlings early
- Remove leaf litter before it breaks down into compost within the stone
- Hand-pull the few that appear — they lift easily from loose stone
- Top up the depth when the membrane starts showing through
