Thank you for your question. I think the hydrangea variety you pictured is a Hydrangea macrophylla, or large leaf hydrangea (in alkaline soil, judging by the pink flowers). Assuming that is correct, you can prune either in the fall or the spring, as this Extension article indicates: https://extension.oregonstate.edu/gardening/flowers-shrubs-trees/general-care-hydrangeas

Hope this is helpful. Good luck!
