I believe in recycling old tires as flower planters in theory but in reality they almost always seem to turn out really ugly and unintentional. These aren’t so bad here but I still think other options would look a lot better. Clover Chadwick of Dandelion Ranch flower shop in Los Angeles disagrees though and really seems to love her tire planters — she’s recycled a whole mountain of them to create a very “urban chic” garden design outside her store. She’s known for repurposing old and vintage items as planters and the tires were inspired when she became annoyed by all the garbage in her neighborhood.
It might not be something that really appeals to me but I have lots of respect for the effort and the principles behind it!
