How to divide Iris in Spring…Because I know things can get away from us and we miss the optimum times to do certain garden chores. It works very well and you can still get blooms.
How to Divide Iris in Spring is a simple yet effective way to separate those Iris you missed last Summer and Fall. You find a clump that is overcrowded and struggling and you want to divide it.
I can see so many garden enthusiasts shaking their heads already. You don’t divide Iris in Spring!
Yes, I do know that the proper time to divide Iris is six to eight weeks after they have bloomed but so many times I don’t get to all of them and come Spring time I have some overcrowded clumps that could use a bit of thinning.
But rest assured I have used this method for years with 100% success.

Find Dividing Point
Here is my clump of Iris that needs to be divided. The center is obvious and you have rhizomes fanning outward from it.
Decide which rhizome you want to remove and follow it back to the center. With your garden knife cut the rhizome off where it attaches to the mother rhizome.
Divide Iris rhizome from mother
You may need to dig around the connecting area to get a good view of it, then slice as close to the mother rhizome as you can. Take your shovel and dig up the rhizomes freed from the mother.
Dig Out Iris Rhizomes
Dig down deep to get underneath the roots of the rhizomes, this way you preserve any blooms that may be already forming on them and it may go ahead and bloom.
You can see I left a nice sized hole where I dug it up from.
The rest of the plant is undisturbed, it will bloom just as if nothing has happened. (just to the left of the tip of the arrow)
Find a nice spot where you want to place your dug up Iris, dig a shallow hole and mix in a bit of Bulb Fertilizer (this is the one I use) into the soil.
I placed the freshly dug up Iris in my Secret Garden I am developing in my back yard. You can see it there next to a Foxglove I transplanted. This coming Summer they should both give me lots of lovely flowers!

One thing I do enjoy about Iris is they are constantly reproducing giving me loads and loads of plants to move about to fill in empty spots or trade friends for more colors. There are so many!
I have toured two Iris Farms the past couple of years and I shared all the beautiful blooms here IRIS FARM VISIT
and here SUPERSTITION IRIS GARDEN
