Chinese rhubarb: how to prune it?

  1. After flowering, cut the flower stem off just above the ground, or leave it for the decorative seed heads.
  2. In autumn, cut the yellowed and dead leaves off at the base.
  3. In summer, feel free to remove torn or damaged leaves; new ones will follow.
  4. Wear gloves and do not leave cut leaves lying where children or animals can reach them.

How much to cut, and how often?

  • There are 2 pruning periods a year: August and October. 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: When tidying up, do not cut off the buds on the rootstock: next spring’s new leaves grow from them. Chinese rhubarb is poisonous: wear gloves and keep clippings away from children, pets and livestock.
