Just dug up the large bed of iris I got and planted last year.60 + Iris in a large bucket of water hoping to drown all those little pest.
Was best thing to do from what I read.
I am new to growing them well kinda had bunch of old purple and blue ones at the old house and never had any pest problem with them.
I brought some with me and planted them by my mailbox and they are doing fine.
The small bed iris are doing fine as well,but after researching I discovered what I did wrong in the large bed
I covered them in early spring to fight off weeds
So any safe weed killer for iris so I wont have to weed everyday.
