How To Kill Morning Glory
Tips on how to kill Morning Glory (field bindweed)
I have a very serious infestation of morning glory weed (the kind with the little white flowers) on the corner of my lot, and cannot seem to get rid of them with anything. We spray them with round-up and the leaves die back, but then they come up from the roots again! Can you tell me what else there is to kill them?
Answer from Zamzows Lawn Expert
You have one of the two hardest weed to get rid of that grow in the Treasure Valley. I have said for years if you have morning glory or Canada thistle the easiest way to get rid of it is to move. What you have to do is spot spray the morning glory once every two weeks until you kill the whole root system off. Morning glory will produce as much as 60 feet of root on one plant. All along this root is dormant growth buds. Once you kill the foliage and part of the root up pops one of the growth buds and you have to spray that plant. Just walk and spot spray the morning glory every two weeks for most of the summer. Do not let this weed go to seed as the seed can still germinate even after 50 years.
I would use Zamzows Ultra Broadleaf Weed Killer. Ultra is herbicide concentrate that kills 200+ broadleaf weeds and won't kill your grass (if used as directed). You can see the fast-acting results in just 24 hours! This amazing product works even in cool weather climates! Many other competing broadleaf weed killers don't. It is also rainproof in as little as three hours!
