How to Grow a Hairy Mountain Mint Plant

Plant hairy mountain mint in an area that has dry or semi-dry soil most of the year. Avoid areas that have wet, boggy soil. Rocky well draining soil is ideal for this native mint plant.

Dig planting holes slightly larger and as deep as the nursery pots or starter pots. Space the plants 18 to 24 inches apart to give them room to mature and spread.

Grasp the hairy mountain mint plant gently at the base of the stems and, with your other hand, carefully work the nursery pot away from the roots.

Set the mint plant into the hole. Check to see if the hole is the right depth by holding the plant so that the base of the stems are level with the natural soil line. Adjust the depth of the planting hole as needed.

Push soil back around the root-ball of each plant and press it down gently to secure each mint plant in the ground.

Water the mint plants in by soaking the soil as deep as the planting hole. Then water once a week or when the top 1 inch of the soil feels dry.

Spread a 2-inch-thick layer of compost around each plant throughout the planting area. Spread the compost layer in a circle that extends 6 to 8 inches out from individually planted mint plants.

Cut back hairy mountain mint plants in late fall or early spring to maintain a tidy garden area. The stalks and leaves will die back each winter with the first frosts and new shoots will emerge in the spring. Use clippers or pruning shears and cut the stalks 1 inch above the soil line.
