Lavender, belonging to the mint family, is grown for its fragrance, color and medicinal properties. This small shrub radiates from a central mound, reaching about 24 inches tall. Certain varieties of lavender are hardy down to USDA zone 5, where the temperature does not drop below -20 degrees F. With knowledge on how to create the right environment for the plant, you can keep it healthy and attractive.
Purchase a 4-inch tall lavender plant in the fall. Alternatively, take a cutting from a bud-less lavender stem after the plant blooms. Plant it in a pot with well-drained potting soil and keep the cutting moist, but not soaked, until it starts to grow a vigorous root system.
Choose an area to plant your lavender with full sun and well-drained, alkaline soil. Lavender prefers light soils such as sand and well-drained loam.
Dig the soil to a depth of 8 to 10 inches with a spade, breaking up clumps and removing any rocks and weeds. Lavender does not do well with competition. Mix 1 inch of small bark mulch 6 to 8 inches deep to increase drainage in heavier soils.
Plant the lavender so that the top of its root ball is even with soil level. Space multiple plants 2 to 3 feet apart in rows 3 to 6 feet apart.
Keep the lavender moist, but not soaked, to help establish it. Watering once or twice a week should be enough. Once established, it is a drought-tolerant plant.
