15 years ago I removed my Chinese elm hedge, which was 35 feet from my house. Now I have two or three growing by my foundation. How can I kill them for good?
Killing Chinese Elm
Certified GKH Gardening Expert
Cut the tree seedlings and paint the fresh cut with undiluted Round-up. The fresh cut will cause the plant to pull the Round-up into its system and will kill it. You may need to repeat 2-3 times if the roots grow deep, but it will work.
