Lilies only bloom once per year. That's the nature of the plant. Those lovely green leaves are busy making food and helping the bulb store up energy to bloom again next year.

In your zone they will not bloom again if you will not chill them for several weeks in winter.

Thank's for the feedback.

Yes you need to give your Lilies a chilling period. They will not bloom again inless they are given a period of about 6 weeks where they are frozen. It is best if you can leave them in the pot and freeze the whole thing. After that they will regrow. In zone 10 this is a problem willl bulbs that NEED to bew frozen like tulips, daffs, lilies, etc.
