What's eating my zantedeschia 'captain tendens'?

Zantedeschia 'Captain Tendens', like all coloured calla lily cultivars, is a garden and container flowering plant. Aphids cluster on new stems and spathes; slugs and snails shred leaves overnight. Thrips cause silvery streaking on spathes. Deer and rabbits will browse the foliage where they have access. Aphids are typically the most persistent problem.

Distorted new growth, sticky honeydew on leaves, and clusters of soft-bodied insects on stems and flower stalks. Blast off with a strong jet of water; apply insecticidal soap spray or introduce ladybird larvae as biological control.

Ragged holes in leaves and chewed-off emerging shoots, especially after rain or overhead watering. Apply iron phosphate slug pellets around plants; lay copper tape on containers; hand-pick at dusk.

Silver-white streaks and flecking on spathes and leaves; distorted flowers in heavy infestations. Remove heavily infested spathes; spray with insecticidal soap or spinosad-based product; introduce Amblyseius cucumeris mites under glass.

Clean-cut browsing of stems and foliage, often overnight, particularly in suburban or rural gardens. Use physical fencing or wire cloches around plantings; apply deer-repellent spray to foliage in deer-prone areas.
