I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
You could use the herbicide glyphosate (an example product is Roundup). This herbicide will kill most green things it is sprayed on and breaks down quickly in the environment. Give it a week to move in and begin to kill the weeds. Then the area could be mowed or cut to the ground with a string trimmer and covered with weed barrier.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
