Gardeners can grow more than 30 types of lavender species, according to Washington State University. All of them are known for their scented foliage and vibrant, purple blossoms that make for a stunning addition to any landscape. Lavender plants are very hardy. You can dig them out and quickly replant them should you ever need to reorganize your landscape's layout.
Choose a new gardening site for your lavender plants. The shrubs require full sun--aim to give them a minimum of six sunny hours per day--and well-drained soil, such as on a slight slope.
Prepare the gardening area. Use a spade to breakup the soil to a depth of 6 to 8 inches. Amend the soil with 3 to 4 inches of compost to improve drainage and aeration.
Dig out the existing lavender plants with a spade, starting in the early morning when the plant has not yet been weakened by the sun. Work the spade in a circle around the plant. Start digging at just beyond the edge of the lavender plant's outermost branches, as the majority of the shrub's roots are within this circumference. The more roots you can retain, the faster the plant will get established in its new location.
Dig a hole in your new planting site that's 1 1/2 times wider than the removed lavender plant's root ball and an inch shorter than the plant's root depth. This shorter height allows for some settling and ensures the plant won't be deeper than the surrounding soil, which can cause rotting of the plant's stem.
Place the transplanted lavender plant into the hole. Fill in the hole around the plant halfway with the removed soil. Water the area to help the soil settle, then fill the hole in the rest of the way before watering again.
Water the lavender once a day, using enough moisture to soak the soil to a depth of 8 inches. Reduce watering to once a week as soon as the plant is established, symbolized by the appearance of new growth on the shrub.
