Yellow corydalis: when to prune it?
In July or August, when the plant has become untidy.
Yellow corydalis: how to prune it?
- Cut the whole plant back to about 5–10 cm above the ground: fresh foliage appears within a few weeks.
- Cut off faded racemes to limit self-seeding.
- In March remove dead or damaged leaves.
How much to cut, and how often?
- One pruning period a year: July–August.
What does it mean for wildlife?
- Yellow corydalis flowers in April–October, when it attracts bees.
- If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
Caution: All parts contain alkaloids and are poisonous if eaten. Keep children, dogs, cats and grazing animals away from the plant, and take care when weeding or tidying.
