How Do You Prune Ajuga

Cut the ajuga back to 1 to 2 inches above soil level after the flowers finish blooming. Use pruning shears to cut the spikes by hand, or mow over the patch with a lawn mower.

Will ajuga rebloom if you deadhead it?

Ajuga flowers mid to late spring. After flowering, the plants may be deadheaded to improve appearance. Large areas may be mowed at high setting. Spent flowers should be pinched off stems.

How do you control an ajuga ground cover?

Cover large areas of ajuga to be removed with impermeable black plastic sheeting (weed mulch or heavy garbage bags). Anchor it with rocks, and leave the area alone for at least four weeks. This removes both light and water, drastically inhibiting growth.
