Gardening

I mostly agree with Kurtzapril4, but do have some other ideas.

Where I differ is with the "Then this." (pic 5) - it looks like a radish to me. The seeds will stay dormant for years and just randomly sprout (generally when tilling brings them to the right sprouting depth). I scatter plant them for the root development (builds the soil) and we eat a lot of them. The one in the bottom right of pics 1, 2, and 5 (small) is a very prolific weed. Pic 7 left looks a lot like sorrel and the one on the right is clearly a brassica but it's too early to identify for sure.
