How to prune oxalis tetraphylla

As flowers and leaves die back; fully cut back when dormant in winter. Snap or snip off spent flower stems and dead leaves close to the soil. At dormancy, cut all remaining top growth to ground level and allow the bulbs to rest dry until spring.

Tidy as needed during growing season; cut back once at dormancy. Oxalis tetraphylla needs very little pruning. Remove spent flower stems and any yellowing or damaged leaves at the base as they appear. When the bulbs go dormant in winter, trim dead top growth back to soil level. No structural pruning is needed — the plant regrows neatly from its bulbs each season.
