How to prune lupinus 'chandelier'

Deadhead throughout flowering (late spring–midsummer); tidy in autumn or early spring. Cut faded spikes back to the nearest lateral shoot. Once all spikes have flowered, cut back to the basal leaf rosette and clear dead material in autumn.

Deadhead after each flush; full cut-back once annually. Prompt deadheading after each flower spike fades encourages a second flush of the distinctive yellow blooms. Cut spent spikes back to a lateral bud or basal leaves. After all flowering is done, cut plant back to its leafy rosette. Remove all top growth in autumn or early spring to refresh basal growth.
