Plant with the roots downward and the scales upward, cover with soil, and firm well to prevent the formation of air pockets in which the tiny rootlets can become dry. Two or three additional good soakings prior to freeze up will ensure good root growth. The better established the bulb is prior to freeze up, the better it will withstand the rigors of a long, cold winter. Label your lilies after planting. Not only will you know where to expect them in the spring, but you'll know what they're called when an admiring friend or neighbor inquires.
Mulches conserve moisture, keep soil cool, and prevent weed seed germination.
Mulches also tend to slightly delay the emergence of the lilies in the spring, which could mean the difference between frost-damaged and healthy bulbs. The use of fresh manure is NOT recommended. Good housekeeping means cleaning up and removing the dead foliage in the fall. Most problems associated with lilies are fungal-related, botrytis being the most common disease associated with lilies on the prairies. Symptoms are root rot and browning of stems and leaves.
