After much trial and error my husband and I have figured out how to propagate lavender organically without growth hormone. This is very important to gardeners committed to organic gardening.  Cut about a 3 to 4 inch softwood cut from new growing stems on your existing lavender plant. Remove the outer "skin" on the stem at the base of the cutting, as well as leaves at base (see photo). Place in a clear glass jar with less than a half inch of clean water at the base. Place in a sunny window sill and keep that amount of water at the base of the jar. It is very important to keep just a small amount of water at the base - this is key to the success of establishing roots. It should take 2 to 4 weeks to establish roots ready for transplanting into a small terra-cotta pot....
