for those who live near a river or stream and want to do some terracing, i found this not too long ago and think its really neat.
i wonder if there is any eatable plants that we could do this with.
what about olives in a less wet environment with almost the same method. they root pretty easily when layered or touching soil, can be pruned to keep close to the wall, and give you olive oil, they dont need that much water. what does anyone else think.
I'm only a couple of years into growing olives and I'm really pushing their tolerances, so I don't have a whole lot of experience. the only problem I see is that they grow rather more slowly than willows. practically that means that gathering enough stakes for a retaining wall project could be more difficult and potentially damaging to existing trees. could also mean that the wall isn't stabilized before some destabilizing event occurs, such as heavy winter rains. other than that, it wouldn't surprise me if olives worked quite well.
