I’m going to turn about 1000 sq of grass into hardwood mulch for future berries. Getting rid of the grass is the tricky part. The area is large enough that I don’t want to screw around with individual cardboard boxes under the mulch to kill the grass. Not gonna use Roundup either to start this project.
I was looking into getting 250 foot rolls of cardboard to put under the mulch to kill the grass. Any experience with this? Good idea, bad idea? One layer or more? A flute or B flute preferable?
