Ajuga, or carpet bugle as it is also commonly known, is a genus of perennial evergreen ground cover species prized for their distinctly blue flowers in the spring. Depending on the cultivar, ajuga can have either an upright or creeping and spreading growth habit. Creeping cultivars use underground stolons to naturalize and spread in the landscape and result in more plant material in the soil. It thrives in shady locations and moist soil. Ajuga is considered to be one of the common ground covers with the least propensity to be invasive. A combination of manual removal, temporary watering cessation and maintenance weeding will help to strip ajuga from an area where it's no longer wanted.
Water your ajuga the day before you intend to commence removal to ease pulling of the plants up by the roots and clearing the soil.
Don a pair of gardening gloves. Grasp the crown of the plant between the thumb, forefinger and middle finger down at the base of the plant right up against the soil.
Curl your remaining fingers around the plant and pull steadily up and out of the soil trying to remove as much of the roots and plant tops as possible. Repeat until you have removed as much of the plant material as you can.
Run a rake through the soil to lift up remaining roots, rhizomes and plant foliage tops. Use a weeding fork to dig down under and lever out deep or thick roots and rhizomes to the surface.
Collect all removed plant material with the rake and discard in the trash or compost pile.
Refrain from watering the immediate area where the ajuga used to be for several weeks to a month to allow the soil to dry out and choke off new ajuga growth.
Revisit the area every five to ten days for a few months, pulling any new ajuga growth that you find and discarding it.
