Yep, chickweed. I had a thread on the old forum entitled "Year of the chickweed". It was everywhere here. And not just on my place, it was everywhere. In the end, it really didn't seem to be much of an issue and in fact, I've come to believe that soil health needs something growing...never fallow and dead. These early spring weeds may actually be good for our soil. And healthy soil grows better forages later on.
