Dollar weed and Newspaper
I have been battling the dreaded dollar weed in one of my plant beds for about a year now with little luck. I am determined to win this battle. I have spot sprayed with Vinegar, RU, and Triclopyr.
I only irrigate once a week in the middle of summer, and about once every 3 weeks in winter. The bed currently has 3-4" of recycled mulch.
My plan is to remove the mulch, place several sheets of newspaper down, then replace the mulch on top of the newspaper.
My hope is that the newspaper and mulch will block out the sunlight and the dollarweed will DIE. What do you think?
