Blossoming Questions

I’d appreciate advice on how to over-winter my Endless Summer hydrangeas in urns. For instance, should I move them into the garage (unheated), then when, or give them a special fertilizer? I’m hoping they will re-bloom next year and remain healthy planter plants for several years. I’m in Zone 7b (northern NJ).
I have bought the Blushing Brides online. When receiving the plant, I found some dead spots on almost all leaves. I have asked the staff and they replied it is not the disease. It is only because of high humidity during the transportation. However, I have no experience with this situation. Because I have other Endless Summer collections in my yard, I want to make sure this will not infect my other plants.

I was given a lovely Vanilla Strawberry Hydrangea and the leaves are turning yellow. I read that watering on top can make that happen. I checked the soil and it’s good and have mixed in some food. What am I doing wrong?

I am wondering if I’m doing something wrong since one of our Endless Summer hydrangeas is not blooming. Both hydrangeas were planted at the same time. We added some soil meant for Azaleas. The hydrangeas are in the shade all day. We have wrapped a soaker hose around each plant so they get watered at the same time. The flowering one is planted next to a man hole which limited its growth on the right side. They are planted in a heavy clay soil. Please help! How long should we be watering them?
