Lavender, a member of the mint family, is a shrub that can grow up to 24 inches in height. While there are 20 to 30 different species of lavender, it is the English variety that is most prized for the high-quality essential oil it produces. Propagating lavender plants by cutting is considered a better method than planting seeds from a lavender plant, as the seeds will not grow a true form of the parent plant type.
Fill a pot with a mixture of one part sand to three parts peat moss.
Water the soil mixture, but do not make it soaking wet.
Look for a healthy, soft-stemmed shoot on the lavender plant.
Cut the shoot, also known as a heel, so it measures roughly 4 inches in length.
Make a hold with your finger approximately 1-inch deep in the soil mixture.
Strip the bottom two leaves off of your lavender heel.
Dip the end of the heel into the root stimulator.
Place the end of the heel into the 1-inch hole in the soil of your flower pot. Carefully cover the hole up around the end of the heel.
Water the new lavender heel thoroughly. Place the flower pot in a well ventilated area, but out of direct sunlight (reference 1).
Keep the soil in the pot moist for the first two weeks. Afterward, water the lavender heel only when the soil becomes dry.
Transplant the lavender heel after six weeks. Plant the lavender heel in a sunny area with well-draining soil.
