Pond Maintenence in Winter, should you?

It may be cold or and wet 😆 and windy 🤔 😳 but maintenence still needs to continue.
In this one I do pond maintenence such as cut back the plant filter Carex, filter clean and look at the pond koi.
I also mop the koi house roof 😆 yes this is maintenence for me in Winter.
Thanks for joining me in this one and thanks for the support.
