To all of you hybridizers or commercial growers out there, I need some info on growing iris for the fastest amount of increase. Do you split the increase off every year? Wait and divide a 3 year clump? Give me some pointers as to how to handle it ! I would like to see the first bloom ( just to help confirm that it is the "correct" iris), but sacrificing bloom , for increase, would be an option...Thanks...Arlyn

What most commercial growers do is divide every year for Maximum increase.

Feed for growth instead of bloom? I fed too much nitrogen one year and got the most gorgeous clumps of leaves you ever saw for two years running. and talk about rhizomes, it looked like I was trying to grow a cross between irises and potatoes! I had purchased some 'super soil' which is a mixture of all things good for plants then a few months after planting the irises in this nutritious concoction I fed them. no blooms, lots of increase. Had to divide because the new increase grew out of their beds and fat rhizomes were perched up on top of walkways and patio stones.

I hadn't thought of that! Initial bloom, like I said ,would be nice, so One could be sure it was the right iris, but from then on, it wouldn't matter. Split them often, and feed them..............Thanks Lucy and Dee..Arlyn

I grow sibs and JIs, but I divide a portion every year into very small sections. Looks like rows of garlic. It usually then takes two years to sales.
