Lemon lily: when to prune it?
In March remove last year’s dead foliage; after flowering cut off the flower stalks and, if you like, the foliage in July.
Lemon lily: how to prune it?
- In March, cut the dead foliage down to just above the ground.
- Cut the bare flower stalks off at the base after flowering.
- If the foliage looks tatty or yellow in July, cut it back to about 10 cm: fresh green growth follows.
- Remove faded flowers regularly to keep the clump tidy.
How much to cut, and how often?
- There are 2 pruning periods a year: March and July. You don’t have to prune in every one.
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: Daylilies are very poisonous to cats. Do not leave trimmings where a cat can get at them.
