I have tiny green weeds across much of my flower beds. When they do get established they look a lot like clover. I spent ages pulling out the shoots one by one yesterday, but it took me a long time to do a small patch. What’s the best way to get rid of them quickly? Would a hoe work (the roots are shallow) and when using one, do you just leave the uprooted weeds on top of the soil to decompose? Thanks!
