Killing off weedy vines w/out hurting Periwinkle

There's a section of my yard that was always pretty much maintenance free - it was a nice patch of periwinkle. This summer, however, I didn't keep a close eye on things and the next thing you know, the patch is overrun with creepy vines that seem to have invaded and spread quickly.

Is there an herbicide that would work for this area - something that wouldn't kill the periwinkle?

Nope. It would sure be handy but, so far, no one has invented such a product. What kind of plant is the culprit?

RE: Killing off weedy vines w/out hurting Periwinkle

The first course of action should be to try to pull/weed out the vines. If you can't get them out, you can get rid of the vines with Roundup if you're very careful. Fill a jar or small bucket with the Roundup. Carefully dip into the solution as much of the leafy ends of the vines as you can pull away from the groundcover. Put down pieces of plastic to protect the periwinkle from the liquid until it has dried on the vines. Then it will not hurt the periwinkle. Be sure to wear protective gloves while doing this since it's not a good idea to splash around in herbicides with your bare skin.

Another method that can work is to cut out the bottom of quart or half gallon milk jugs or one or two liter soda bottles (depending on how large the vines and how thick the periwinkle.) Pull as much of the vines into the bottom of the jug as you can and set the jug down on the ground, keeping the periwinkle out of it. Spray into the top of the jug to wet the leaves of the vines. Leave the jugs in place till the vines and jugs have dried so you don't transfer or drip the liquid onto the periwinkle.

Some vines may take more than one application to get good control. But be sure to give plenty of time for the herbicide to work. It may take up to a couple of weeks to show results since it has to transfer to the roots and kill them before the tops die off.

Thanks for the replies all. Sandy - sounds like a do-able approach, I'll give it a try!

If the vine is woody, a product called Vine-X that has an applicator brush on the bottle may work better.
