What Is This Weed Under My Cotoneaster and How Do I Get Rid Of It?



Ask the Expert: killing weed without killing cotoneaster
What is this weed growing under my cotoneaster shrubs, and how can I kill the weeds without killing the cotoneaster?  I have Trimec Plus for post emerge grass weeds, but would that be safe to spray on the cotoneaster to get at the weeds underneath? Rex

Plant Expert Reply:

What you have is called vetch. It is a weed that we find often in lawns, but will also present itself in shrub beds. Trimec Plus is a product for lawn/turf application only. I would not recommend spraying it on your cotoneaster since it is a “broadleaf” killer. Cotoneaster is considered a broad leaf and therefore Trimec would damage the Cotoneaster. Instead I would wick it with a contact killer like Roundup or Hi Yield Killzall.

The method of wicking involves applying the chemical only to the plant you want to kill. You can surround your cotoneaster with a piece of cardboard and then spray the weed. Or you can take a piece of absorbent material and dip in chemical and then touch the weed.

I usually pull this weed and apply a pre-emerge granule to the soil to keep it from coming up again. I use a product called American weed and grass stopper about twice a year in my beds.

You can get all of the products I mentioned at your local garden center and nursery.

  2. You can use a grassicide which is a chemical that only kills grasses. The one we sell at our garden center is called Hi Yield Grass killer. This product will kill the grass but will not harm the cotoneaster.

    I have the weed Vetch popping up all over the lawn in in the flower beds and ivy.
    There is way too much to pull out. What can I use to kill it without killing grass and flowers and shrubs?
    Thank you.

  5. Rich,

    You can use trimec to kill the weed in the lawn and not hurt the grass. However, this chemical will not work in the flower bed or the ivy because it would also kill the plants you want to keep.
