Question From: Madison, Wisconsin, United States
Q: How do you rid the garden of lilies of the valley, or at least reduce the number of them?
There are three methods. Dig it out - a killer job and it may take several tries. Smothering using cardboard or heavy black plastic and several inches of mulch. Leave it in place for a year. 3- Spray it with RoundUp - it may take two applications. Read the directions carefully. Roundup kills what it touches so you can do a lot of damage if you are not careful. Good Luck and thanks for visiting Yardener.com, Nancy
