Why does my big, beautiful, healthy-looking plant never get the big, pink blooms it used to?

When can I unwrap burlap from a hydrangea in spring?
In most cases, you can unwrap them now. But it depends on how sensitive your hydrangea varieties are to the cold and where you live. As this article explains, Hydrangea aspera and H. macrophylla are the most sensitive to cold, while H. arborescens and H. paniculata are the most cold-hardy.

When the temperature is reliably above 0 degrees F, you don't need to protect any hydrangeas and you can unwrap them.

I have 3 hydrangeas--one of unknown variety as it was here when purchased home and 2 nikko blues that I planted. Unknown is in area that has become shaded over time but gets afternoon sun; nikko blues get sun all morning. I have deer problems and they have feasted. I tried pruning just below where deer ate but they do not seem to be recovering for past 2 years. What can I do to resurrect them or must give up? I try spraying them with repellant and fencing in winter. Unknown is shown in photo but nikko blues look same.
I cut back one to the ground and it grew nearly a foot in one week, so I cut the others back as well. They all grew back completely and I even got a few blooms on the Nikko blues! Thanks for the suggestion!
Dear downtoearthdigs, I had read the articles you mentioned previously. When I did the pruning, it was at the end of the season before winter and I took care to remove dead canes and leave live ones. They just haven't come back. I will try cutting to the ground. These were beautiful for years before the deer damage.
Prune back all the dead material and see if the plant can recover from the root.

I have several Hydrangea's that haven't bloomed for 2 years. We had a hard freeze 3years ago when they were just starting to bloom. I am not sure if that is what caused them to only leaf out or that our trees have gotten larger and we only get about 4hrs. of late morning sun. Is there anything I can do to promote blooming? I sent you a picture of one side of my garden. I wanted you to see the tree line so I took the picture from a distance. If you look on the right of the steps, top down, you can zoom in on the Hydrangea's. I appreciate any advice that you give me. Thank you so much, Josie
You will want to protect your hydrangeas for the winter. The unusual cold is damaging the buds most likely. This article will help: https://www.gardeningknowhow.com/trees-shrubs/hydrangea-winter-care-how-to-protect-hydrangeas-from-winter-cold-and-wind.htm
