Fred - Very impressive garden boxes! You really created a lovely raised garden area! Looks like your daylilies love it there!
I, too, was wondering about why you add lime to your soil?
I can not use wood here because of the humidity, rain, and termites. But I do make raised beds using concrete blocks. Works well, just a little heavier lifting and I have to use construction adhesive (instead of screws or nails) to secure them together. I add the concrete tops to each of the cinder blocks which serves as a nice place to sit while I weed and prune the raised bed and plants. For the middle bed and the top bed, I use recycled plastic boards. A bit pricey, but they don't rot or attract termites.
