How to Stake Irises

Bearded irises are stars of the May garden, but the flowers are so large that the stem can snap in wind and rain. In mid-April, stake tall varieties with a single stick to support the flower stem.

  • Push the stick in behind the flowering stem, a few inches into the ground.
  • Use a paper-covered wire twist tie to secure the stem to the stick. You can position it behind a leaf to make it less obvious.
  • Irises emerge at different times, so check every week or so for any tall enough to stake.

One simple task done ahead of time in April helps to ensure these seasonal stars look their best and avoid any mishaps in the spring showers. It's worth doing in a thoughtful way so as not to detract from the flowers.
