This is a good method for propagating lilies:
best done when its time to plant, so once you see them in stores its time. Lift or purchase and clean a mature, virus-free lily bulb. Snap off a few scales from the bulb as close as possible to the base Place in a plastic bag with a 50:50 mix of slightly damp peat-substitute and perlite Shake the bag and fill with air before sealing and labeling and place it in a warm dark place such as a hot water cupboard. leave until growth appears - between 2 to 12 weeks depending on conditions and variety. a similar method if you live in a warm area is to plant the scales direct in soil outdoors once temperature and weather are stable.
Too much cold and moisture will rot the scales.
