What else to prune in those months? October
Arrowhead: how to prune it?
- Cut yellowed leaves and spent flower stems off just above the water surface.
- Leave the tubers in the bottom alone: next year’s plant grows from them.
- Leave the cut material on the bank for a day so small creatures can return to the pond.
How much to cut, and how often?
- One pruning period a year: October.
What does it mean for wildlife?
- Arrowhead flowers in June–August, when it attracts bees.
- As a native plant, it feeds more insects than a non-native species.
