I pull mine out by hand. You have to be very vigilant.

I have read that trying to pull them out by the roots is the worst thing you can do, because each tiny broken root will grow a new plant!

I am sorry you want to get rid of your morning glory. I get it that they can become invasive. Have you tried to train it up a pole/trellis and keep it controlled? They can be so lovely when they are controlled.


If you truly want it gone, it is a long process you have to get every vine going to the end and getting all the roots. It may take one or two seasons to make sure you have found them their roots/feelers travel.

Chemicals can be used, but I avoid them at all costs because not only do they kills off other things you may want, but if you have dogs, stray cats or children in the neighborhood you could be setting up for a dangerous situation. Plus these chemicals leach into the watershed and can poison drinking water (yes, I am a bit of an old tree hugger--safety first!)

Good luck!

If you ask most people about using chemical means for killing weeds most will say no they do not wish to use chemicals because .......

  • I can tell you that it will take years for you to kill off the morning glories in your lawn if you do not use some sort of chemical weed killer and in fact most say it will never happen.

  • If the glories are isolated and you can smother them you may be successful over a period of time but if these are scattered in your lawn then smothering will not work unless you want large patches of cardboard/newspaper with mulch on top in spots all over your yard.
  • Some people do say they have had good luck with a strong vinegar solution (white vinegar with a few squirts of Dawn liquid soap). Cut glories about 1-2 inches from the ground (place all pieces in a throw away bag), spray with vinegar solution (hot sun is best) and wait a few days to see if it seems to be working (this will kill other weeds with deep roots) but it may leave a small brown spot in lawn for a few weeks.
  • Here is some information from a university web site:
  • Herbicide control for Morning Glory is much more effective. If you are looking to control it on your lawn, herbicides that have 2,4-D and dicama will kill Morning Glory and not your turf.

    To get the most effective control on your turf, apply one of these active ingredients several times over the summer months.
  • It has been suggested that with herbicides that have 2,4-D in it should be applied in small areas with 1 gallon of herbicide and 1 gallon of water. Make sure you follow the instructions on the package.
  • Glyphosate is another herbicide that can control mature Morning Glory plants without damaging desirable plants nearby. It has also been suggested to be applied with a 2% solution of glyphosate herbicide. It will take a few weeks for the weeds above-ground to die off, and it will take several applications for you to have completely eradicated the Morning Glory.
  • If you are worried about glyphosate ruining desirable plants in ornamental areas, carefully paint the leaves with the 2% glyphosate herbicide solution with a foam paintbrush to reduce the drift of the herbicide.

these plants are notoriously hard to eradicate - pulling them by hand or chemicals are the way to go

I've been stuck with morning glories for years because my next door neighbor planted them and they got into my back yard. While pretty, they grow over everything else you've got. Months ago, when I saw the seedlings come up, I went out and started pulling them up by the roots. It's easy. Each day I'd pull up 50--70, until I didn't see anymore.


As the weeks went by, I'd find less. Today I pulled up about 15. I don't have a huge yard, so this is doable. I'm pretty sure I won't have the problem this summer, with them taking over everything the eye can see in my yard. Next year, I hope to see far fewer sprouts come up.
