I tried this last night and got a few beds weeded in less than an hour. Most were dandelions once I got up close and personal! I just used a small serrated knive, worked like a charm. Even with the quack, I was able to grab a hold of the quack, throw the knife underneath and gently pull the long trail of roots under the soil until I could cut them off.
Even took care of a few weeds this morning before heading off to work at 6:30 am. That's how fuss free it is! Glad I saw your post.
Thanks again!
