Help! Moldy Rhizomes!

I'm a newbie iris grower and I received my order from Ross Road Iris last week...I opened the box and they looked wonderful...big and healthy! I didn't have time to deal with them until today and when I went out to the garage to get them, I noticed most had developed fuzzy green, black, and white mold on the leaves and roots (totally my fault for leaving them in my hot humid garage all week wrapped up). I know with daylilies I can soak them in water mixed with alittle bleach to kill any mold that develops on their roots, but I wasn't sure if I should do the same with the iris since they seem to be more water sensative and don't like getting too wet. What is your advice?


Here's a couple of pictures of what's going on :(

This one is about the worst with its big black mold puff on top :(

I would do the same for the iris. Just dip in a light bleach solution, maybe 10% bleach, try to wipe off as much mold as you can, then separate them out flat to dry well before you plant. Probably not even necessary for the bleach solution, but seems like a nice safeguard to me. Just be sure to get them dry before planting. They still look quite healthy, I've planted much worse looking rhizomes & they have done great.

Thanks :) So do I soak them in the bleach solution for a few hours, or just dip them and take them right out?


RE: Help! Moldy Rhizomes!

Dip. Then dry completely. Irises do not like to be moist- they need cool and dry, unlike daylilies.

You can trim down the tops a little bit to get rid of the mold. They should be fine.
