Rat’s tail cactus: how to prune it?

  1. Remove dead, shrivelled or damaged stems at the base with a clean, sharp knife or scissors.
  2. After flowering, shorten overlong stems to the length you want.
  3. Let the cut dry for a few days before putting a cutting in compost, if you want to reuse the cut stem.

How much to cut, and how often?

  • One pruning period a year: June.

What does it mean for wildlife?

  • A houseplant lives indoors, so wildlife hardly notices the pruning. Healthy clippings can go on the compost.
