How do you kill vines in the flower bed.. with out killing plants?

You pull them out.

Keep pulling and hand weeding ...making sure to get the all of the roots!

Hard work. Put on a thick pair of gloves, get a trowel to loosen the weeds if necessary, have a shovel handy for the tough ones, and pull, pull, pull. If you just break off the weeds or use a weed eater, you are only adding work...putting seeds back in the ground to germinate.

Make sure you have a container close to put the pulled weeds into...you don't want their seeds to spread.

I saw on TV last night a hint for removing sod that would work with weed pulling.

The night before you want to do this chore, soak the ground really good to soften the soil...this will do 50 of the work for you!

If they cannot be pulled,smother them out with newspaper,cardboard and heavy black plastic

Definitely keep digging - it's super important!

Spray ONLY the leaves of the vines with round-up and NOT before a rain. Rake/pull up after they die.

Be aware that nightshade grows vine-like with little purple flowers that turn to red berries in the fall. Some nightshade is harmful to animals and humans and also can cause allergy related rashes if you come in contact with it. Found this in my yard last summer for the first time in over 20 years and it is back this year growing throughout my forsythia bush.

This is just the thing! I find this works wonderfully. You have to cut the vine and then brush this on the top of where you cut it. Bonide It will travel down to the roots and kill the plant. Cut it wherever it is coming back and brush that on. Be careful not to get it on the plants you want to keep.
