How tough IS it?
I cleared a 2 foot wide strip alongside the gravel drive- this sort of melds into a wide nature strip alongside. The understorey is pure ivy! I hoiked it out but obviously have left many roots and rootlets.
If I dig out 10cm of soil, edge the cleared area with concreted-in 'kerbing'; put a weed barrier on the exposed soil, fill it with 5cm hardcore and 3 cms of pebble, is the ivy likely to break through? I will attempt to prevent spread across the ground by using the kerb as a pruning line but I am worried that the ivy runners will manage to break up through into the gravel.
I know it's not a triffid but it IS tenacious!
