Oriental lilies such as Stargazer (red & white) or Casablanca (pure white) are easy to care for once they are established in your flower bed. Both are hardy to zone 4-9.
As the saying goes, “lilies like their heads in the sun and feet in the shade”. Plant Stargazer in full sun/part shade in well-drained, fertile soil that is slightly acidic (ph6). In hot climates lilies prefer morning sun and afternoon shade. Too much sun can prematurely fade the flowers.
Plant in early spring or fall, 3 times the depth of the bulb (6-8″). Add a teaspoon of bone meal to the bottom of the hole.
Lilies need a steady moist but not soggy soil. They should get at least 1 inch of water per week from rain or manual watering. In the heat of summer, place 2″ of mulch around the plants to conserve moisture, keep the soil cool and keep the weeds away.
Fertilize with a 10-10-10 twice a year, in early spring and again just before the flowers open.
The sweet scented lilies bloom from mid to late summer ( July-Sept).
They can grow 2 1/2-7 ft tall and may require staking for support.
Aphids- can transmit viral disease,
Bulb mites, weevils and red lily leaf beetle.
Common fungal diseases: Foot rot (Phytophthora cactorum)-stems rot just below soil surface can also attack new shoot tips.
Botrytis elliptica, gray mold-tops of emerging shoots wilt and die.
