This project is on hold...my downstairs neighbor had a leak that necessitated rerouting some water pipes. In order to get to the area so they could work, they cut down a large shrub that sat where the block raised bed now sits. I asked the landscape guy if I could replant the area, and they wouldn't have to bother. He liked the idea, and I copped a few more square feet of prime CA garden area...gratis.
They have finished the piping, and now they need to re-stucco, paint, and be gone.
I'm going to try to dig out this agave and put it in the raised bed. These things can be lethal to muscle around...you need goggles and plenty of big thick towels.
