When I built my backyard out of them, the tyre shop nearly paid me to take them...but that was nearly 10 years ago now.
Funny thing about that, and surely I'm not alone here either...I had a very shithouse backyard. Locals will know the Islington of old to some degree, well I was on fern St. It was a mix of industrial and residential going back a very long way. The soil was a fucked up mix of coal dust, spot/ash, rubble, litter, and sand. The deepest I dug down there was about 3 feet and it was still heavy with old broken up bricks and similar. It was wrapped around a cracked and fucked concrete slab with a hills hoist in the middle. Anyway I gave about zero fucks for yard maintenance the grass was waste deep for most of my ownership! Then (foolishly?) A woman moved in with me (we had been on/off/on/off for a very long time by then) and I had the house revalued which triggered a bit of a clean up. I decided to landscape the yard to some degree.
Being a bit hard up for cash at the time I decided to build up the garden bed out of car tyres...tiered up to 3 tyres high then fill them with compost (mostly coffee grounds) and potting mix. I think I've talked about this before, so hopefully not boring anyone too much yet. Ummmm...the woman involved was unable to envision where this was going and expressed the doubt fairly clearly quite often "this is stupid" and "it looks like shit" kind of talk. After about 3 months (I used to be a really good gardener) I had a the garden greened out and under control without very much work at all, just some very selective planting (mostly plants that I liked but grow like pests and some fruit trees I got for free).
where was I going with this? Ummmm...not once did I get anything like a "oh...now I see it,chat was a good idea".
not sure how this all relates.
