Answer: Depending on how long they have been in the ground, it may be time to worry, but lilies can take quite a while to root and then grow. Six weeks would not be at all unreasonable. You might very carefully dig down and see if they are sprouting underground or not. (Do not break off the growth tips). Lilies should be planted in a rich soil and in a well drained location; in a soggy spot they will rot. During the establishment phase they also need regular moisture (but not soggy soil) to promote rooting, so the dry spell we had may have delayed their growth if you did not water them. If after all that you think there was a problem with the bulbs, please contact Burpee directly. Their customer service number is 800-333-5808.
