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.

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:

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

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
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.
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.
I planted a large bed shaded by an old maple tree with hostas, astilbe and ajuga. The tree had to be taken down this winter. I plan to move the hostas and astilbe, but will the ajuga be all right in what is now a sunny bed? There is a *lot* of ajuga in the ground, and I really don't want to relocate it if I don't have to.
Yes, you can grow ajuga in sun or shade.

We have a beautiful focal point in the very front of our yard that was a gorgeous stand of ajuga with the lovely spring blooms. It has been declining the last several years and I have determined that it has succumbed to Southern Blight (we are in Atlanta) or crown rot. Everything I am reading suggests digging it and the soil out and replacing. I have ajuga in other areas that is lovely. I would prefer to keep the ajuga, but not the way it is now. Can you suggest a way to salvage the ajuga, or dig out and replace with something similar that will make a nice combination planting with the surrounding daffodils?
You could certainly dig it out and replace the top few inches of soil with a combination of compost and topsoil. Then purchase some of the newer varieties of ajuga or dig some up from your other stands.
If you are worried about the pathogen infecting new ajuga, you can try one of these:

Large areas of ajugas are dyeing in my garden. Do you think it could be grub worms?
It could be! Your photos did not come through, so I am unable to assess the damage.
