Set out plants in the spring, 12 inches apart in part shade/sun. That the soil be well-drained is Ajuga’s most important requirement; if necessary, add compost and coarse sand to heavy soils to lighten and improve drainage.
Keep soil moderately moist, watering to a depth of 6 inches during periods of drought. Mulch in winter without covering the tops of the plants: this will prevent damage to the shallow roots from alternate freezes and thaws.
