I apparently have prickly lettuce (very easy to pull but I have tons of them), bull thistle (my gigundo plant from last year), common mallow (a pain to pull), and common mallein. I already knew I have dandelions and grass that spreads from the neighbor's lawn (sigh). Of course I also have the ever-prevalent trees, which we finally pulled or dug up on Thursday night, thanks to the soil that was saturated quite deeply! I was too tired to take pictures of the trees after pulling them. It was a lot of work and Nathan had to help with the three largest ones. I think they are elm trees but I'm not really sure. They line our fence on one side and provide excellent backyard privacy in the summer.
The rest of these are generic photos from the Internet - this first one is the prickly lettuce. It only grows in one section of my garden.
