What else to prune in those months? November
Hardy begonia: how to prune it?
- Cut the dead, limp stems off just above the ground.
- Let the bulbils ripen and drop first, or collect them to plant elsewhere.
- No other pruning is needed.
How much to cut, and how often?
- One pruning period a year: November.
What does it mean for wildlife?
- Don’t cut more than you need to: what stays standing gives insects and birds food and shelter.
Caution: Leave the spot alone until June: the tubers are still in the ground, even if you see nothing. Hardy begonia is poisonous: wear gloves and keep clippings away from children, pets and livestock.
