I have white fuzzy spots on the backs of hydrangea leaves and their woody stems. How do I get rid of them?

It sounds like you have mealy bug on your hydrangeas.
Try 'Yates Nature's Way Citrus & Ornamental Spray (Pyrethrum Plus Oil Pest Spray)'. Controls a wide variety on insects pests on many edibles and ornamentals.
