Dear Iris

Thank you very much for your inquiry. The weeds in the garden are not my specialty, I will tell you that up front, and nay herbicide applied over the top can be very injurious, as I am sure you know. Second, a vine weed is the most difficult to control, particularly in flowers. My first suggestion is to paint herbicides on the weedÂs leaves. Literally get a paint brush and paint the herbicide on the leaves. This insures no contact on any other portion of the garden. You will need to work back to the source, and it will take time, but you can use Roundup for this situation if you are careful. Once you get to the yard, use Weed B Gon MAX plus crabgrass control as this contains Trimec plus quinclorac. (you can use this to paint with as well). In the lawn area you can spray the grass with no effects.

Again, thanks for the question and let me know if you have more.

Respectfully

Alas, I know this weed very well. It takes forever to paint all the tiny leaves and you drip it any way onto other areas. This worked well for me....Cut off the stems to about 8-10 inches and unwrap/detangle them intact from the plants. Place the cut ends into a container filled with 1/2 roundup, 1/2 water. I like to bury the container partway into the ground to avoid tipping. Don't water to aviod splashing the herbicide out of the cup. I cover the cup as well with a plastic bag to avoid fumes from damaging the other plants. You can reuse the cup several times for each bindweed you wnat to remove. This is how I removed bind weed from the plants I could not dig out and move. I have to caution you that on 2 instances, I had a little root burn on the plants where the bindweed roots were in close contact with the other plants roots. Also, some plants will be sensitive to the fumes of the roundup. This isn't a perfect method, but it worked well enough for me to completely get rid of all the binweed in my yard so I call it a good solution.

Other soulutions that worked for me were

Keep the plant cut off at ground level until no more growth sprouts. ( This takes FOREVER )

Dig out all the precious perennials you can and put them in containers while you continuously spray any growth the roots put out until the roots are exhausted.

Dig out any trace of root and sift all the soil for root bits. ( this works 70% of the time for me )

Above all, NEVER let this weed flower and set seed. A pre emergent herbicide works to control existing seeds but the plants with roots already need to treated with one of the above methods.

Thank you both for your help. I am determined to win the battle over this weed and will try these methods ASAP, (if the rain ever stops here in western Maryland)
Thanks!

I have never seen a more tenacious and overwhelming weed than this stuff!

I am ready to give up, and let it become my ground cover, instead of grass.
