This question was asked by
We followed all directions for taking care of the plant but now after all original giant beautiful flowers have finished blooming and all large petals have fallen off, the dark green large healthy leaves are turning brown. Will they bloom again? Not sure what to do!
Once your lilies have finished flowering, you can stop watering them and then cut just the flower heads off leaving plenty of stem on. Allow the stem and foliage to die back naturally until it has turned yellow and hollow. (This is usually towards the Autumn time.) You can then remove the stem and foliage at this point. Leaving it all to die back naturally will then feed the bulbs, allowing them to flower again the following year.
Leave the bulbs where they are (outside) over winter as they like a cold dormant phase, they just don’t like to get waterlogged as they will rot.
You can then give them a fresh layer of compost in the Spring and feed them with a diluted tomato feed during active growth periods.
Hope this helps.
