We went to the Habitat for Humanity ReStore to look for bricks, but didn't find any. Instead, we found some white ceramic floor tiles that had bits of green and blue glass stuck in them that would make nice stepping stones. We also went back over to Lowes to get the brick and mulch.
We picked up 95 bricks, some pea gravel, and 6 bags of Cedar mulch to match the Cedar raised bed boxes and loaded up the Saturn. I dug the trenches and laid the brick while Katie planted some more onions, carrots, cauliflower, peas, lettuces, and weeded behind the fence. As I walled in sections of the garden, Katie came by and started filling in with mulch. It took most of the morning and afternoon to get it "finished" after going to Lowes, but it looks nice and clean now.
There was some risk of frost last night, so we covered the peas, asparagus, spinach, onions, and some of the strawberries with painters drop cloths.
