I have invasive ground cover and I want to take it all out. Was thinking of Covering it all with cardboard then maybe some mulch so it will not be unsightly until Spring.

Do you think that will work?

Hi Marilyn,
Why not give it a shot. I have never tried this with groundcover, but the principle is the same...if you deprive a plant of light and air, it should die.

Marilyn, I've done a combination of this and plastic to kill vinca - it DOES work, but you have to make sure you get all the groundcover. In my case, the vinca comes back into my yard because it originates outside my yard, and I can't get to the source.

Vinca is a mess. Finally got rid of mine when they excavated to put in new patio. Have not seen any new sprouts so am guessing they got it all. It has been a year now. I had liberally doused the area with weed killer before they came. I don't want to do that area as I want to plant something else (don't know just what yet)

It is just the first 12 inches from the brick edge that has soil, the rest is rock, all is in deep shade.

I will remove the pots and misc other stuff and cover with the cardboard and some mulch to make it look a bit less unsightly for the HOA of my townhouse complex. Do I need to cut the groundcover back before I do this?

I don't know that it's necessary, but it wouldn't hurt. And white vinegar will help kill it, without ruining the soil, or so I'm told. Thumbs up

Marilyn, if I were doing this, yes I would cut it back. If nothing else, that would make it easier to cover. That's a cute little area!

Thanks, it is my only bit of ground. Everything else is rock and concrete. When I planted the groundcover, I just wanted a bit of green but the ajuga has gone Crazy and is now creeping over the rocks.

Has anyone else used vinegar to kill the stuff before I do the lasagna?
