Bar Harbor juniper is a variety of the creeping Juniper. It is a low-growing ground cover (reaching only a height of 6 to 12 inches) that is native to Mount Desert Island, Maine. Bar Harbor juniper can spread up to 6 feet and is an excellent choice for coastal areas where sea spray is an issue. Like all junipers, it's tolerant of most soil conditions; however, good water drainage is a must. Transplant your Bar Harbor juniper in the spring from a nursery-grown plant or from an existing plant in your garden.
Prepare the new planting site, which should be in full sun. To help with water drainage, turn over the top 12 inches of the soil and mix in 2 or 3 inches of compost or peat moss. This helps improve drainage in heavy soils as well as help retain moisture in light sandy soils where water drains too fast.
Remove out your existing Bar Harbor juniper by carefully digging around each plant, about 6 to 8 inches away from the crown and 6 to 8 inches deep. This is easiest when the soil is moist. Dig a bit deeper or wider if you feel you are cutting into the roots. Gently push down on the shovel to lift the plant out of the soil. Try to get up as much of the roots as possible. Shake off the excess dirt and gently separate the roots that are tangled.
Plant the junipers in their new location. Dig holes so that they are planted to the same depth as they were previously planted. Set the junipers in the holes and spread out the roots. Lightly pack the soil around the plant. Space multiple plants 4 to 6 feet apart.
Water the transplanted Bar Harbor junipers with about 1 to 2 inches of water.
Cover the site with 4 to 6 inches of bark, pine or similar organic mulch to help keep soil temperatures more consistent during the winter months. Keep mulch about an inch away from the crown of the plant and in the spring, remove all but 2 inches of the mulch.
