Daylily: how to prune it?

  1. During flowering, pick off faded blooms without damaging the buds next to them.
  2. Cut flower stems off at the base once they have finished.
  3. Let the leaves die down in autumn and remove them in March, before the new leaves appear.
  4. Brown leaf tips in summer can simply be trimmed off.

How much to cut, and how often?

  • There are 2 pruning periods a year: March and September. 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: Do not put buds infested by hemerocallis gall midge on the compost heap; put them in the household waste. Daylily is poisonous: wear gloves and keep clippings away from children, pets and livestock.
