    Daylilies are in peak bloom in June. It is a good time to buy new daylily selections for your garden to ensure you get the color you desire. Visit a daylily farm for the best selections, and plant them in full sun for the best flower production.

    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.
