Q.Getting rid of Morning Glory

Zone 84057 | Anonymous added on September 20, 2018 | Answered

I have used Round Up on the various spots of Morning Glory in our garden this summer. There are still plants coming up. What is good to use and when before the freezing temperatures come? Also, does Preen work if I use it in the early spring on these area when the Morning Glory is coming up in spots all summer.?

Morning glory makes thousands of seeds and the germination rate is high. Unlike bindweed and bigleaf morning glory, typical morning glory doesn't have a huge root system. You can pull or hoe individual sprouts until all the seed is exhausted which may take several years. A pre-emergent like Preen may prevent sprouting although I think you will need to reapply it near mid-summer. Follow instructions on the container.
