Tiger lilies are hardy perennial plants that flower each summer. They usually have bright orange blooms but can produce pink or yellow flowers as well. They grow up to three inches in diameter and they have a strong sweet smell. The best location to plant them is one that gets full direct sunlight and excellent irrigation. The plants can produce dense ground coverage because crowding is not an issue. Once you have found such a spot, dig small holes to plant the roots. Add organic compost to fertilize the soil. Tiger lilies do better with organic fertilizer than with chemicals. Make sure the roots are on top of the compost and then cover with soil to where the roots are about two inches below the surface. Fertilize the flower bed monthly to insure that the flowers are getting proper nutrition. Do not fertilize when the tiger lilies are dormant during the winter. Water the area immediately and then once a week, or more in dry arid climates. It is a good idea to spread a two to three inch layer of mulch around the flower bed to help with water retention. The best time to plant them is in the early autumn. In warmer climates you can plant them into the late autumn as well.
Since tiger lilies are considered a delicacy by rabbits and deer, if they are indigenous to your area, place human hair on the ground around your plants and they will stay away. These flowers are not affected by insects and disease problems. They are prolific growers and can be propagated by digging them up, separating their tuberous roots, and replanting the roots to grow new flowers. Some varieties produce bulbs and the bulbs can be transplanted to grow new blooms.
If you follow these simple steps, you will raise flowers that will visit you every summer to add color and fragrance to your garden.
