Now, these farmers are restoring coal mining land with lavender. They spread the lavender on the floor to cut the buds and bundle the stems to sell for cooking. We stripped the bottom two leaves off and we'll dip that in water and rooting hormone. They save small leaf clippings and plant them to grow more lavender. The oil floats to the top. Just drain the water off of it, which we keep the water, too.
