Yeah. It could end up looking kind of, ‘Trailer Park’ in some cases, so I can see his hesitation.
My beds are tall enough and at an angle where you really don’t notice the areas between the beds when you’re looking at the garden as a whole.
I have one long edge where the garden meets the grass I would love to use the shingles as it is our main walking path. The grass creeps into the garden all the time. Say I was just looking at tius and thought if your country type decor I thought you or others would like it. Turning old dressers into seating.
I have huge piles of wood chips from trees we’ve had taken down the last 1-3 years. If I put them down thick enough (like 6 inches), they will retard weeds for a while, but as they break down, the weeds are back. That’s what I did some years ago when we had chip piles from another bunch of trees taken down & the chips gave up the ghost last year & garden walkways are now a mess.
I intend to put a thin(ner) layer of chips over the shingles so they don’t show - an inch should do it. My garden will still look great, a couple of loads of chips should do the covering job ( instead of dozens of loads), & the shingles will keep the weeds down for years.
Now I can’t wait to get the golf cart tire back so I can use it/trailer for hauling.
