Q.How to kill a morning glory plant
First, I want to say I think the Morning Glory is a beautiful flower BUT very invasive. My problem is the plant belongs to my neighbor. It grows under my porch into my hot water heater, under my hot tub and has gone so far as to grow under my house and inside it as well, into my bedroom and living room. I have talked to my neighbor and she won’t do anything to control it and has said kill it if I want.
I agree with you, beautiful but a very invasive plant!
