I received a potted Mona Lisa Lilies. It has 2 plants. When I got it 3 had already bloomed. And petals have fallen off. Another 1 has bloomed & there are 4 more that haven't bloomed yet. In the last 2 days 1 plant the leaves are falling off. I have only watered it once. It gets about 6-8 hours of sunlight. Am I doing something wrong? I'm new to Lilies. I would also like to know if & how I could put these outside. I love how beautiful they are & the fragrance is wonderful. Thank you in advanced. Any info on Lilies is welcome!
