Caring for Carpet Bugle Plants
It is self-seeding, so if you don't want any unexpected pop-ups, deadheading would definitely help. Removing some of the runners periodically can also help keep this ground cover in line.
Should Ajuga be deadheaded?
Most Ajuga are evergreen throughout most of their growing range and will require little if any pruning. After flowering plants can be deadheaded if desired.
How do you prune bugleweed?
Cut off the flower spikes in late summer after the flowers have faded. To shear back a large area of bugleweed, use a lawnmower set to a high blade height. To keep the plant under control, rigorously prune runners twice a year. Be sure to remove any runners escaping the desired planting area.
