How to Plant and Grow Irises

  • Planting for Irises should be done in the mid-late summer.
  • Plant them in a location where they can receive plenty of sun and no other flower shades them. Better Homes and Gardens recommends 6 hours of sun light a day.
  • Make sure to plant them in rich-well drained soil.
  • Organic Gardening recommends to barely cover the rhizome when planting. Also make sure you point the “leafy end” in whatever direction you want it to grow.
  • Group the irises together in groups of three to five and space the groups about 2 feet apart.
  • Install aeration tubes to help the roots establish themselves.

Tips on Growing Irises

  • Make sure not to add mulch to your irises because too much moisture will actually rot the rhizomes.
  • Don’t forget to prune back the foliage in the fall.
  • Every 3 to 5 years in the late summer divide your irises.


Don’t forget to add this beautiful summer flower to your garden. It’s easy to grow and makes the perfect addition.
