Transplanting lavender in the fall is the perfect time unless you live where there are harsh winters. Then you would want to transplant the lavender in the spring. Transplanting lavender in the fall gives the plant enough time to establish a strong root system before the heat of summer.
How to Transplant Lavender
Water the lavender plants thoroughly before transplanting. Select the new location for the lavender. Make the hole just as wide and deep as the previous lavender plant hole. Prepare the soil with a cup of bone meal and a cup of compost. If it is a clay soil, mix in sand to loosen up the clay.
Sand should be patted around the bottom of the plant to help with good drainage of the soil. The sand mulch throws up heat to the leaves of the lavender stimulating more blossoms.
How to Care for New Lavender Transplants
Newly-transplanted lavender plants need to be watered regularly especially if there are drying winds. The lavender will die without enough moisture. The regular watering will make more spikes, lengthen the stems, and cut out some of the stress of summer.
For the first summer, you need to cut off the spikes so the plant’s energy will flow into the foliage and roots , not the blossoms.
