    Once daffodils', surprise lilies' (Lycoris squamigera) and red spider lilies' (Lycoris radiata) foliage has turned yellow, you can mow or cut it down. If you remove foliage while it is still green, you decrease the amount of energy available for the bulb to store, which will reduce flower size next year.
