Removed all the sawdust and organic matter to decrease soil biological activity in the structure (to prevent rot), leveled the dirt, added gravel to cover dirt a couple inches thick, built a dimensional wooden deck with a trapdoor over the cold sink . . . soon will install the greywater bathtub supports on top of the existing gravel and then fill in with more gravel until it’s level up to the trim pieces on the decking.
Also, check out this crazy squash seed which was germinating inside its parent squash in our pantry!
The yellow buds are Oregon grape, and the last one is a knapweed seed head from last year. I’m not sure about the white one, but hepatica seems a good guess! I can try to get better pictures of the leaves and habit today.
