How to prune sea urchin cactus

Any time of year, as needed for damage or dead tissue only. Use long-handled tongs to hold the cactus steady and sharp, sterilised scissors or shears to snip dead or mushy tissue at its base. Let the cut dry and callous for 24–48 hours before watering.

Rarely — only when dead or damaged tissue is present. Sea Urchin Cactus needs almost no pruning. Remove dead, damaged, or shrivelled pads with clean, dry shears. After flowering, spent blooms drop on their own — no deadheading required. Never cut into healthy green tissue; the globular form is natural and should not be shaped.
