I am not an experienced gardener by any means. But, when I saw the asiatic lilies at lowes, I couldn't help myself. Since I planted them two weeks ago, five out of eight have lost their flowers. Will they reflower this year, and if so, do I cut off any part of the stem to help them? All of the plants still look healthy. I'm just not sure what to do now. Any help would be appreciated. Thankyou.
