Choose a planting site with good drainage and full to partial sun. Wait until the soil has warmed in the spring to plant Vintage lavender.
Clear the area of all foliage and debris. Add a 2- to 3-inch layer of organic matter, such as compost, peat or manure, to planting areas with sandy or clay soils. Mix this into the native soil to a depth of 6 inches or more. Level the area with a rake before planting.
Dig planting holes the same depth of the pots holding the Vintage lavender transplants and slightly wider. Space the plants at least 6 inches apart.
Remove each Vintage lavender from its pot and gently loosen the roots. Place the plant in the hole with the roots spread out.
Backfill around the plant with the removed soil, and then water the area well to settle the roots in place.
Add a 1- to 3-inch layer of mulch around the base of the Vintage lavender, but keep a few inches of space clear next to the plant's stem to prevent damaging it.
