Based on this comment, I think the idea is that if you plant trees within the bend of a wall, they are shielded and heated from more than 180 degrees. https://

You only get this benefit for tree right along the wall, which is not much agricultural area. Seems like a strained justification.

- jessriedel 7y agoThanks. You're talking about espalier? https://en.wikipedia.org/wiki/Espalier https://en.wikipedia.org/wiki/Espalier I could only find a single picture of something like this on a curved wall. https://images.app.goo.gl/AXPFnXgE47K1vm5U7 https://images.app.goo.gl/AXPFnXgE47K1vm5U7 If the tree is going to be pinned to the wall (as opposed to being free-standing and surrounded by the wall), I don't really understand how making it curved helps with absorbing heat or shielding from weather.
- Razengan 7y agoSlightly tangential, but having lived mostly in bare concrete jungles, there's something so aesthetically pleasing about green things growing on a backdrop of bricks or wood. A soothing harmony of nature and artifice. :)
