Hi Anne, some helpful suggestions from our community:

"They are called Mealy bugs n coz lot of harm to plants and leaves. Best way to keep them away is plant Lavender, Marigold, Lemon grass around your garden which will attract Lady birds who love eating these pests. Also attract honey bees as well.Lady birds are needed to kill them"

"Mealybugs, hard to control, I remove the most infected leaves and I squash the others, could try jet of water using a hose. Check the stems as well."

Hope this helps?

On a smallish indoor plant I have used ethanol on a cotton bud (vodka!) to clean off mealy bug - but I wouldn't want to tackle a hydrangea! Maybe pick off the worst leaves as suggested and try wiping some others with a bit of cotton wool soaked in ethanol.

Another suggestion for you:

"Also looks like they could be cottony cushion scale, which are definitely hard to pull off the leaves and a bit more difficult to treat."
