    Hi everyone. I've tried this post in another area & got no replies. It's puzzling me - does anyone have any thoughts on this?
    I have a selection of different irises in my garden which I planted 4-5 years ago. They are all in the same place, a long thin bed, and have multiplied, producing lots of large, colourful blooms. Last year and now this year again some of the buds are failing to fully open and are either shrivelling up or turning slimy & deformed.
    Does anyone have an idea about what might be causing this? It applies to all the plants, whether I've brought them indoors as cut flowers or whether they are still in the ground. There don't appear to be any obvious pests on them. Could it be an overcrowding issue? I am considering splitting them. When would be the best time to do this?
    Many thanks for any help. lindycoView attachment 176222View attachment 176223

      Hi

      this can happen when we have heavy rain and it collects between the petals and ends up rotting them ... so its not a disease or insects the iris bred today are huge flowers ..

      best time to split is August as it gives them time to settle in before winter

      Thank you, Spruce. Good to know it's only the weather that's caused it.
      Cheers. lindyco
