While I was convalescing Hügel number 1 became infested with ragweed, which I finally pulled out. However, the roots on that stuff are no joke, and I lost a significant amount of soil. Luckily I had plenty of compost to back-fill it with and enough straw mulch to make it look halfway decent again. Unfortunately it's a little late in the season to be planting new things, but I'll see what I can do.
