How to prune tiger lily

Deadhead immediately after flowering (mid to late summer); cut stems to ground after foliage dies back in autumn. Snip off individual spent flowers with clean scissors. Leave all green stems and leaves intact until they yellow completely, then cut the whole stem to soil level.

Annually — deadhead each spent bloom, then one hard cut-back in autumn. Tiger lily needs modest pruning. After blooms fade, deadhead spent flowers to prevent seed set and conserve bulb energy. Once the foliage yellows and dies back naturally in autumn, cut stems to ground level. Never remove green leaves early — they fuel next year's bulb. Removing stem bulbils is optional but limits unwanted spread.
