I’m trying to “kill off” my “lilies of the valley” to start a vegetable garden, but nothing seems to work. Any suggestions? Thank you very much!
“Lily of the Valley’ is familiar to everyone, loved by some and hated by others. It tends to become extremely invasive and difficult to get rid of unless it can be well contained. Here are a few suggestions you may try:
1. Plants may be destroyed by thorough, repeated digging and with removal of their underground stems or rhizomes. Any pieces of rhizome that are left will sprout out and develop into plants. It often takes two or three attempts to completely rid lily-of-the-valley by digging.
2. The herbicide glyphosate (also known as Roundup) is another control option. Glyphosate is a non-selective, systematic herbicide that destroys virtually all plants onto which it is applied. However, lily-of-the-valley is a very tough plant. Two or more applications of glyphosate may be necessary to completely destroy lily-of-the-valley.
3. Some people love this classic perennial. Invite gardeners in your area to “dig your own” for free. Free plants have a way of disappearing on their own.
