    Mealey bugs. Wipe them off while you only have a few. If they are on the stems scrape gently with a butter knife. Soapey water can help too.
    Marne la vallée, basically just outside Paris 🇫🇷, but definitely Scottish at heart.

    I think it’s Hydrangea Scale ... info and advice here

    Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.

    Agree with Dovefromabove, I just spry all my Hydrangea's with soapy water.
