My goodness! What is this little obnoxous thing? It comes up thick like this in every single flower bed I have. It's not all over, but where it is, it's thick like this. This morning I've been hoeing it. Since it doesn't seem to have deep roots, I'm hoping that will get it. I suppose I must sit there and sort of nake the soil around and pick the little things out, so they don't root again. Right? If not, tell me what you do, please.
