Control is recommended where natural resources are being protected or as part of a stewardship plan. However, this plant is very difficult to eliminate so it may only be possible to suppress it while allowing other plants to establish. Contact the noxious weed program for advice on managing large infestations. Field bindweed Convolvulus arvensis closely resembles hedge bindweed, but its leaves and flowers are smaller and it tends to grow along the ground instead of climbing.
It is a very problematic weed in many crops. Because hedge bindweed is so widespread, property owners in King County are not required to control it and we are not generally tracking infestations. We can provide advice on how to control hedge bindweed, but there is no legal requirement to do so.
The bluish-purple flowers are pretty, but the relentless vines wind their way around our fence and plants, and I can never seem to get ahead of them. Every year, they pop up overnight like something in a Tim Burton movie.
Is that because they dropped seed in the fall? Is there a spray or something I can use in the spring? Don't let Jan scare you, Allison; although the vines do self-seed like mad, true morning glories, that is members of the Ipomoea species pronounced "eye-Poe-ME-ah" , are annual plants, not perennials; and can be well-controlled in areas with freezing winters.
The vines are not self-supporting, so they are typically grown over a fence, or famously in some Chicago neighborhoods up string running from the ground to the roof of a building. The individual flowers are ephemeral; they open a rich blue in the morning, become purple in the heat of the day and then crumple and die that same evening.
But there can be a lot of them, and every flower gives birth to a seedpod that will drop its distinctive dark, little rock-like seeds onto the ground for next season. So yes, Jan—you can prevent them in future seasons. If you apply a corn gluten meal product that's labeled for use as a pre-emergent herbicide to the soil early in Spring, those seeds should be inhibited from sprouting.
If you miss that 'prevention' window, the young vines are easily hoed or pulled out of wet soil. Mulch fence lines and other non-planted areas heavily with wood chips, or sheets of newspaper or cardboard covered with soil.
Flame-weed any young sprouts that appear at the outskirts or spray them with a high-strength vinegar or herbicidal soap. It really isn't that hard; and if you prevent seeds from dropping over the summer, you will get zero volunteer vines the following year.
As I learned the season I collected every seedpod from my morning glories for an organic seed house. Morning Glories have taken over a raised flowerbed in my backyard.
Every year I have to constantly pull them out. We have even sifted the dirt thru a screen. I would appreciate any suggestions you might have on getting rid of them. Thanks, Donna in Bensalem PA I have a wonderful raspberry patch in full sun that gets overrun with a flowering vine that looks like a morning glory. Is there any way to rid my sweets of this intruder?
My neighbors have it and have been battling it for years. Seed from field bindweed can persist in soil for up to 60 years. Scary, huh? Its roots can grow up to 30 feet deep. It grows up and over anything in its path. Much like pole beans, bindweed's stems rotate in a circular pattern until they make contact with a solid structure fence posts, other plants, etc. Each stem wraps around the object as it grows. If you have it, prepare to battle with it for years.
Weed scientists at Oregon State University have told me over the years that the best way to get rid of field bindweed is to pull it up, over and over, at least every three weeks. Its roots should be depleted in a couple of years if you persist. Identifying field bindweed can be a bit tricky. Its arrow-shaped leaves grow opposite each other along each stem.
