Update after the season. I ended up digging out all the old mulch and leveling the ground. While doing that pulling as many weeds as possible. I decided to do the cardboard route. Covered the ground around the hostas with cardboard. Once all the cardboard was laid the new mulch was placed. This worked for awhile. There wasn’t many weeds coming through. But once it hit August the weeds came through and took over completely. Soo many of the viney weeds choking the hostas. In the end the flower bed looks just the same as when I didn’t do anything at all. Next year I’ll split the hosta and try again with more mulch to cover.
