How to prune cardinal flower sinningia

Deadhead during flowering (summer); cut back at dormancy (autumn–early winter). Pinch or snip individual spent flowers or entire flower stalks at the base. Once the plant dies back for dormancy, trim all dead stems to soil level. Store the tuber dry over winter.

Annually — deadhead through bloom season, one full cutback at dormancy. Sinningia cardinalis benefits from deadheading spent tubular flowers to encourage further blooms. After the flowering season ends and foliage dies back, cut all stems to the soil surface as the plant enters dormancy. Avoid cutting healthy stems while in active growth — the plant naturally manages its own shape.
