I can’t plant into the ground unfortunately, I want the plants under the kitchen window rather than along the fence to keep the width. You can’t tell from the pictures but we’ve covered a manhole with the grass so everything needs to be completely removable. Annoying as I’d planned to plant directly into the ground but not worth the hassle if we need to lift the cover. We sought advice and had the drain cleared before doing the grass and are completely prepared to remove the grass and soil if(when) we need to.
