How to prune true lily

Deadhead immediately after flowering; cut stems back only in autumn once leaves yellow. Snap or snip individual spent flower heads below the seed pod. Leave the full stem and leaves intact until they turn yellow in autumn, then cut to the ground.

Deadhead each bloom as it fades; cut back once annually in autumn. True lilies (Lilium spp.) need targeted pruning at specific stages. Deadhead spent flowers promptly to prevent seed set and redirect energy to the bulb. Do not cut back the stem or foliage after flowering — the leaves must stay green to photosynthesize and replenish the bulb for next year. Cut stems down only once foliage yellows naturally.
