Q. grass growing in my Ajuga plants

Among my Ajuga ground cover I have grass growing. I can’t seem to control the grass, as I try to pull it out but there are too many. Is there a spray (or any other chemical) that will kill the grass and not kill the Ajuga? Thanks.

A lawn weed and feed would also kill you ajuga as it contains a herbicide.
Beside continuing to hand pull the grass you could try to use vinegar in a spray bottle to spot treat the grass. You would still need to be careful how you spray it.

Q. Containing ajuga

I am considering planting either silver beauty or burgundy glow around two trees that are surrounded by stone(see photo attached) Should I be concerned about the ajuga “creeping” onto the lawn?

As you mention, Ajuga can indeed spread and creep into new areas quickly. To prevent this, you could add edging around the border in most locations, but I am concerned that this could damage the tree roots

These articles have some ideas but most of them will require regular upkeep:

Q. Will Ajuga grow by the Bay in VA?

We need a hardy groundcover around our condo. The soil can be sandy. Plenty of shade if need be. Lots of sun in areas also.

Ajuga is hardy in zones 3-9 and prefers part shade-shade. This article should help

Q. Ajuga

I love my Ajuga and have it out by the road. I have grass growing up in it and want to kill “the grass” NOT the Ajuga. I was told to spray it with buttermilk because of it acidic content, but it’s not working to well. Any help would be great

You can purchase a selective herbicide that targets only the grass. Make sure you read the label carefully and only apply if it says it's safe for your Ajuga.

There is a product called Grass B Gon, by Ortho. I'm sure other products are available. It is an herbicide that kills grass but not other plants. Being next to the street, car tires and winds will kick up seeds of all sorts. I wonder if a pre-emergent next spring would help. Ajuga spreads mostly by stolons, not seed so a pre-emergent won't hinder your groundcover.
