We planted two little tomato plants last week. We're considering this part of Botany 101. I don't know how many tomatoes we'll actually get from just two plants, but I'm sure the girls will love picking them, and then eating them.
I've also tried to pretty up a corner of the back yard. Wind funnels back there and trash (from who knows where--ok, the elderly lady who lives next door keeps dumping stuff there) accumulates. We raked it all up, dug up all kinds of gunk, raked some more, and planted sunflowers and wildflowers. Lining it with bricks has greatly decreased the debris that accumulates. In fact, we've had no more to gather up!
Here are the sprouts of flowers we planted at the back of the house. Lining the area with bricks helps keep little feet off the plants!
