Have any of you ever had scale growing in the folds of the leaves? The ants have moved in and are 'farming' the scale similar to what they do for aphids. They go for the honeydew excreted by the scale. The ants have established colonies among the iris plants.
In other plants you scrape them off, wash with soapy water and sometimes use an insecticide. I have not dug them up yet, but apparently scale can infect the roots too. I've never heard anyone talk about getting scale on their irises.
If you have any experience or advice on the best way to treat this infestation I would love to learn from your experience! I discovered them as it was getting dark. Tomorrow I will investigate further.
