The Weakest Link
To date all of the stone walls that we have built are still standing. Here the certain future failure is rooted in a poor choice of stone. We call stones like this mud stones. They remain soft after they are removed from the ground. This stone will continue to disintegrate in the near future. The novice builder placed it near the bottom of the wall. Replacing this stone will be a major task.
Looking at this photo has spawned an idea. Perhaps the crumbling area of stone could be chiseled out and replaced with the rest of the wall remaining in place. If only half the stone was removed at a time, the stone above should support the wall. Winter would be a good time to try that. The frozen planting bed in front of the wall could be safely walked on with no damage to the plants.
