How to prune tiger nut

End of growing season, when foliage dies back. No pruning needed. Cut old brown stems to ground level at season's end for tidiness. Harvest the tubers by digging — do not attempt to shape or thin the foliage during the growing season as the plant spreads by rhizome and regrows freely regardless.

Rarely — end-of-season tidy only. Tiger nut (Cyperus esculentus) is a sedge grown for its underground tubers, not a shrub or tree. It has no pruning requirement. You can cut down old, brown foliage at the end of the season as a tidying step, but this has no effect on tuber yield. No pruning technique applies.
