    over the summer we had a working group to try and cut back some of the iris' that are overaking our pond...we were led to believe the pond was extremely deep. After adventuring in it's fine to stand up in around the edges so we got in and started hacking out masses of iris' from the centre outwards. We had to stop eventually as the ground was so dry at the edges making it really difficult to dig out.

    Someone was asking if we should be chopping down/cutting back the out iris' now for winter. Honestly i have no idea and now consulting you lovies for advice. Any thoughts?

    Note how low the pond level is! Can't believe how low it has got!!!

      Sorry no one more knowledgeable hasn’t replied so far. I don’t think there is any harm in digging out the irises now. They can take over. Presumably the recent rains will have raised the water level now and softened the surrounding grounds you can finish the work.

        Well, it's obviously a mature pond with masses of what looks like Flag Iris around it. Irises foliage will die back some during the Winter, but some will remain. It won't do any harm to the Iris to thin it out but unless you really want to tidy the pond up I wouldn't cut back the foliage drastically as it's obviously still getting energy from the Sun to store in its rhizomes for flowering next year. I never cut back my Iris in my wildlife pond and only thin them when I need to.
        To be honest, not knowing the real depth of the pond apart from being told it might be "extremely deep" is, from the safety side, not good for carrying out any maintenance on the pond. I would strongly advise that if you know any one who coarse freshwater fishes to ask them to use a float and weight to plumb the depths. It can be done very easily and quickly and if he/she plumbs the length and width of the pond you will have a plan of the pond depth.:coffee::snorky:
