Watch as Better Homes and Gardens shows you how to divide bearded iris plants! Late summer or early fall are the best times for dividing irises. Dig up and divide irises when a clump gets crowded every three to five years. With a garden fork, lift a section of iris rhizomes out of the ground. Separate individual iris rhizomes with a garden knife. Keep only the healthy ones. Cut the healthy rhizome leaves back to four to six inches. To plant irises, dig a shallow hole, then set the rhizome with the leaf fan pointing up. Cover the iris rhizome in soil. Keep these gardening tips in mind when dividing iris plants in your home garden!

Watching this video is obviously a learning too! Sharing techniques on dividing such plant or separating them from crowd is a simple task yet a very significant one. I'm really glad I found this video!
Hi, I have started doing this in mid to late summer but we had so much trouble digging out a clump today. There was no way a garden fork would go into the soil. I had to hack with a mattock around the clump, hacking through many roots in the process, to create s small trench around the clump. Then I had to ask my husband to come out and dig it up with a shovel. He needed to use a lot of power to get it out and I've dumped the clump on a potting table till tomorrow. I tried to saw off a tuber to separate it from the rest of the clump, with a bread knife, but it was too tough. I will try again tomorrow. There are another four similar clumps to remove, divide and replant. You can see one of the clumps on my channel in the Shasta Daisies video at the start, on the far right.Do you have any suggestions on how to remove the clumps if they are heavily entrenched in the soil? Also do you have any suggestions how to divide them if they do not break apart easily?
Easy and uncomplicated. I have some irises risomes with no leaf so guess these are old ones. Mine are very shallow and are coming out easily with a trowel as the soil in that part of the garden is fairly sandy. I wanted to know about planting distance and you gave me the info. Thank you.
Very simple and helpful, thank you!
Very helpful…thank you☺
