How to prune alcantarea imperialis

Anytime for dead leaf removal; pup separation when pups reach one-third to one-half the size of the mother. Pull or cut dried lower leaves at the base — no need to prune healthy foliage. After flowering, leave pups attached to the dying mother to absorb nutrients; separate them with a sterilized knife once large enough and pot in free-draining mix.

Rarely — dead leaf tidy-up as needed; once per lifecycle for pup removal. Alcantarea imperialis (giant bromeliad) rarely needs pruning. Lower leaves naturally dry out over time and can simply be pulled or cut away once fully dead. This monocarpic giant flowers after many years, then declines, producing pups at the base. Remove the dead mother rosette only once pups are well established.
