Ok, I gave Ruth her present! I built a raised planter box for out back. Got a few pictures on my masto.
There’s this drop-off between the patio and the fence where you can accidentally scoot your chair legs off it and wipe out, and we had an idea of blocking it off with a planter. That’s why there’s only two legs: the front edge will sit flush on the pavers, and the back legs will reach down to the dirt!
She DID, in fact, guess what it was; I knew I wouldn’t be able to hide all the preparations. She saw me measuring something out back, and while her first guess was a cat tunnel, she eventually figured it out. But she DIDN’T notice that I’d stolen the absolutely massive segment of waste fencing that keeps falling on our plants, so I still managed to surprise her with the scale of it; it’s 6 feet long, a foot wide, and 18 inches deep. We could even farm potatoes in this thing. (Probably tomatoes and tomatillos the first year, since we need to rotate them out of the back beds.)
