When Easter is over, your lily still has life as a garden plant! So, don't throw away your lily after it is done blooming. You can save the bulb and plant it outdoors. Easter lilies can be replanted outside after the blooms are finished. Plant the Easter Lily outdoors as soon as the ground unfrozen and can be worked. Plant it in a sunny location with well-drained soil. Set the top of the bulb six-inches below the soil surface. Cut off the old flowers, but be sure to leave the stem and leaves. Grow through the summer. Do not cut back the stem until it dies down in the fall. Cut it off at the soil surface. After the soil surface freezes in late fall, mulch the soil. You will see new growth begin in the spring. Your lily will flower in the summer months.
