Welcome to Modern Agriculture!
Deadheading lilies will encourage more flowers to form and prolong their display. It will also divert energy away from seed production, which can reduce flowering performance in subsequent years. If you’re growing martagon lilies, don’t deadhead these as these will gradually self-seed.
Follow this easy advice on deadheading lilies the right way.
Tidy up the lily flowerheads once the petals have fallen, trimming them back to just above a pair of leaves.
