When to tidy pond

I'm not an expert on ponds, but my wildlife pond will be tidied some time soon in the winter, before the spawing season comes. But as I can see from yours, you wouldn't really get spawn in yours due to your pump so can imagine clearing/dividing can be done now or sometime before Spring before the plants really get going.

I don't think there is anything for you to tidy as water irises are not normally pruned unless there is leaf damage. The rest certainly doesn't need attention. Our pond on the other hand needs some serious removal of weed and several plants pruned back!

I would clean/check over my aquarium at least once per month, especially if you have live fish.

If you think that needs tidying you should see ours! I wish I'd done it in the late autumn as many people do, before the water got so cold. I wouldn't touch it, its beautiful.

I've just done mine! Cut my irises down from the frost making them snap! I've got rid of a tonne of blanket weed too!

I cut out the old brown foliage on the iris early spring, but I take the lily leaves away in the autumn/early winter when they turn yellowy/brown. any other dead stems are cut down in the early spring.

it looks wonderful in your photo :o)

That has to be a photo from last spring! :)

Yes Tugbrethil you are right, that was in early Spring.Every plant was then new to the pond.

Thanks
for your comments and advise.
