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!!!
