This raised bed developed a sagging side. I was concerned it might fall. I had to remove the entire side, and re-start from the bottom up.
My original plan was to make it more narrow, because it's hard to reach the muddle. But this is too much hard physical labor for an old, handicapped guy like me.
I had to use that steel fencepost to pry the lower blocks out.
I can see that moles undermined the outside side, causing the soil to sink. I'll fill in the gaps with lava gravel, which I hope is more difficult for moles to dig. Then re-build in place.
I can mulch the difficult-to-reach area so it doesn't need much care this year. It's not a lot.
I'd like to finish before the soil freezes, but I need a break first.
