Poison primrose: when to prune it?
Real pruning is not needed. Remove faded stalks and yellow leaves all year round; after flowering, in May–June, also clear away the old leaves.
Poison primrose: how to prune it?
- Wear gloves because of the hairs.
- Pinch off faded flower clusters with their stalk at the base, without damaging the heart.
- Remove yellow or dead leaves with their stalk at the base.
- After flowering, take away the old leaves and repot the plant in fresh compost.
How much to cut, and how often?
- One pruning period a year: May–June.
What does it mean for wildlife?
- A houseplant lives indoors, so wildlife hardly notices the pruning. Healthy clippings can go on the compost.
Caution: Wear gloves and do not touch your face: the hairs can cause a rash in sensitive people. Wash your hands after handling the plant. Poison primrose is poisonous: wear gloves and keep clippings away from children, pets and livestock.
