Hello! I took out my lawn a couple years ago. I planted clover, mint, and other lovely "weeds" to feed my mason bees, cut down on water, ect. We live along a stream and have a runoff pond on property as well. This winter almost everything has been completely taken over by creeping buttercup! What can I do without picking them all out of the ground or spraying to kill everything that I still want? It's about a quarter of an acre. Thanks!
