This post is about the physical planting of lavender. It isn’t about the area of the country, type or use. Please see other posts for that information.
Gently knock the plant from its pot, spread the roots. Place the plant in a hole that will be big enough for the roots to spread and grow. Mixing a little bone meal into the soil mix below the roots will promote both root and leaf growth. Roots should not be placed directly on the meal, but on a mix of soil and meal. If the stems are long enough, give the plant a little shape by pruning, this will start the stems branching. When you water the new transplant for the first time, you can use a liquid fertilizer instead of plain water. A two-inch mulch of sand will moderate the soil temperature and reflect heat and light up to the plant. More heat creates more fragrant blooms. The sand mulch is important. If you are planting in a pot make sure you choose a very large pot. The root ball is much, much bigger than the top of the plant. I’ve used pea gravel in the bottom of my holes to help with drainage. If you are planting in a pot use at least an inch or more gravel in the bottom of your pot and have plenty of drainage holes.
Place your lavender in the design that makes you happy and allows room for air currents around the plants when they reach maturity. Lavender loves the sun and hates too much wet, so choose a position with good drainage and plenty of sun. They are excellent for rock gardens. Humidity can be an issue in the Southeastern and some Midwestern states. Lavender isn’t fond of damp, still air which makes the plant more susceptible to root rot. This difficulty can be minimized by increasing the spaces between the plants so the air can move around them more easily. Grow lavender with plants that have similar sunlight and watering needs. Select soil that is well worked, well-drained and loose enough you can dig it with your hands. Once established in a garden, lavender is a hardy and drought tolerant perennial. Lavender likes a slightly alkaline soil so adjust accordingly. Some sand and well-rotted manure or compost will get the plant off to a good start.
