Containing ajuga

Question

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?

Answer 1

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:
