Lavender, a multipurpose, perennial herb, grows best in well-draining soil with a pH level of 6.5 to 7.5 and full sunlight. Used for cooking, beverages, medicines, fragrances and landscaping, lavender grows well in gardens, containers and hedgerows. The spiky blooms of this hardy, drought-tolerant herb come in shades of white, yellow, pale and dark purples and blues. Cathy Blanc, Jean Davis, Hidcote Blue and Melissa are all ideal lavender varieties for spectacular hedgerows.
Clear weeds from the chosen planting location four to six weeks before planting lavender. Lay clear plastic sheets over the row, weighing edges and corners with bricks or large stones.
Apply 3 to 4 inches of organic compost and 1 to 2 inches of coarse sand over the planting location and work into the soil at a depth of 8 to 10 inches, using a pitchfork or garden tiller.
Water potted lavender plants and allow them to soak up to one hour before planting in the ground.
Dig holes only deep enough to accommodate the roots of each plant. Space plants according to their mature height. For example, if the mature height is 3 feet, dig holes 3 feet apart.
Remove the lavender from its container and brush away all planting material to expose the roots.
Place the root into the prepared hole and pack soil around the base.
Apply a 1- to 2-inch layer of mulch around the base of each plant, leaving a space of 2 inches between mulch and the stem.
Water lavender plants when soil dries out, but do not allow first-year plants to stress. As lavender plants mature they develop tolerance for drought conditions.
