Growing Irises

You know it's time to split or thin your Irises when they start to spread into the grass (lol).   As you can see by the picture below that is exactly what happened with my Iris patch.

A clump of Irises that I dug up - they are now ready for splitting
After the Irises have finished flowering, simply remove your Irises with a shovel (you will need to dig down 6 to 8 inches to make sure you get the root base).  Then look at each stalk and follow it down to the base, there should be a twisted bulb-like root for each stalk.  Now separate each stalk - you might have to snap or cut the thick Iris roots apart.  (see pictures below)

I was able to get 5 plants out of 1 Iris clump

As you can see Irises have a thick twisted root.

Then simply plant each new Iris in it's new location.  Splitting should be done about every 3 years or whenever you notice a large conglomeration of Irises.


  1. I just love iris, but don't really have enough sun for them. I think I will get maybe 3 rhizomes that bloom this year. :( Your bicolors are so nice.

  2. I noticed that all of your blog images are lovely, and I am a fan of complimentary color schemes, like violet and yellow. And I got hop image, no html needed. Thanks!


Please feel free to leave comments or questions (no question is ever stupid) - They will show up on the blog once I have read through them.
Thank You.
