We harvest ours early fall, sort and ship immediately. Previously we replanted holdovers asap but this winter I stored in damp peat @ 34 deg. They kept well showing no signs of root or stem growth. Replanting now. I expect I could hold them until April with these conditions. Will try next year. This Maryland extension fact sheet has much information about lily bulb handling and storage and well as propagation for cut flowers. http://extension.umd.edu/publications/pdfs/… from the pdf Bulb Storage and Handling Lily bulbs ready for production are available year round from bulb suppliers. Suppliers precool the bulbs for 6 to 8 weeks at 34 to 36°F to ensure that they flower more evenly. Once the bulbs are precooled, suppliers freeze them in peat moss at 28 to 29°F for storage (see photo 3). Freezing the bulbs prevents sprouting, reduces loss of bulb energy reserves, and minimizes disease occurrence. also After bulbs have been precooled, they should not be exposed to temperatures above 36°F for periods longer than 8 to 12 hours or premature sprouting will occur. If the shoots of unplanted lilies have grown beyond 2 inches, the bulbs are worthless. Oftentimes lily bulbs available through local garden centers or large chain stores are held in heated retail areas, reducing the quality of the lily bulb. Although these bulbs are adequate for a homeowner’s purpose, professional growers are not advised to use them for cut flower forcing.
