Every year in Watertown, we have a Life-Friendly Garden Tour, in which gardeners who don’t use chemicals in their yards open their gardens for you to see. This year, I finally signed up to be a part of it. After all, not using chemicals is pretty important if you want to give the bees a nice place to visit. Then if you plant flowers and leave the ground undisturbed, all sorts of bees will show up. I’m still finding new bees, like this long-horned bee on the sunflower.
