    Soil can very, even in a short distance.
    Avoid fertilizing any lawn areas around the shrub, as the excess nitrogen can migrate into the soil area.

    Are the plants the same variety? Is the sunlight conditions different?
    This article will help with the proper fertilizing for healthy, blooming Hydrangea.

    Allow this madame to propose a few possibilities. Sun burned leaves indicates either your hydrangea is in full sun, suffered fertilizer burn or is not being watered adequately. (How insolent or me!) Frankly, I don't think the plant can handle afternoon sun even if the leaves look OK. I'll assume you know whether your plant blooms on new wood or last year's stems and that you prune accordingly. A late spring frost, even though the leaves made it through fine, may nip those blooms in the bud. Too much water causes root rot and the plant will not perform well. And then there is the truism that sometimes the darn plant just doesn't bloom. Here is some good reading; follow the links on the left to your species of hydrangea. http://www.hydrangeashydrangeas.com/wont_bloom.html

    Could it be Cercospora leaf spot? See link: https://extension.psu.edu/pests/plant-diseases/all-fact-sheets/hydrangea-diseases

    Yes, a late frost will nip the bud. Also important is when you pruned them. Some hydrangeas bloom on old wood (bigleaf, aka macrophylla, and oakleaf hydrangea), some on same-year growth. If you have an old-wood cultivar, pruning those dead-looking stems will remove this year's blooms. Too much sun, particularly the hot afternoon sun, also seems to be a factor. If you don't know what type you have, go to a grower's website to view them. Here is White Flower Farm: http://www.whiteflowerfarm.com/all-hydrangeas
