I have a chance to get Nikko blue hydrangeas really, really cheap but they are about 3 inches tall. I live in zone 6 and wonder if I could get them and plant them and either keep them inside my garage or put them in my dining room until spring. I would like to purchase 10 and would be saving a fortune to buy them now this cheap and hold onto them until spring. Do you think either of my ideas would be a good idea?
Yes, you can overwinter the hydrangeas in pots indoors. During this time they should only require minimal care--like monthly watering to keep them from drying out completely. Once spring returns, you can plant them outdoors or keep them in containers outdoors to overwinter inside each year.

I recently purchased a Nikko Blue hydrangea. Some of the leaves had some brown on the edges. I cut them off, but I'm still getting the brown on the leaves. Could it be a disease or am I doing something wrong? Thank you.
This could be a number of things--too little or too much water, over fertilizing, leaf scorch (if planted in too much sun), etc. Typically, in hydrangea, this is caused by a watering issue. Has it recently been planted? If newly planted, there may be gaps in the soil around the root ball that is drying out the roots. I would tamp down the soil around the plant. I would also recommend upping the watering. In addition, it could be suffering from shock.

I bought 2 large Nikko hydrangea plants a couple wks ago (bush/shrub) from a nursery. The leaves became droopy about the 4th-5th day after. What should I do? I've always loved hydrangeas...see them everywhere. I'm devasated. Please help. Thank you.
Daily watering is important for new planting for the first 2 weeks.
Water the shrubs and adding 2 to 3 inches of hardwood mulch will help with moisture retention.

What makes the leaves have brown spots and then leaves fall off?
That is quite normal for this time of year The leaves will start to fall off next month. Don't prune it now or you will lose flowers for next year.

I have nikko blue hydrangea 8 yrs. old. the 1st yr. they were blue. Now they are pink and lavender and have been since. I feed them acidic fertilizer. I have talked with the nursery man and he told me my water is probably neutral. Is there anything now this fall I can do to help them to come back to blue. I cannot change the ph of the water. Pls. help if you can and many, many Thanks.
It can be difficult to get soil down to a low enough (acidic) pH to get hydrangeas to really turn blue. Aluminum is also needed in the soil for the plant to create the blue color. Having a soil pH test done can show you how close you are to the necessary pH of 5.2-5.5.

Aluminum sulfate can help with both the pH and the aluminum requirement:

Only one bloom this past summer! We had a frost so the leggy stalks and leaves are wilted. Adjacent oak leaf and climbing hydrangeas bloomed beautifully...
This particular hydrangea is one of the macrophylla species. These will flower on old wood, so this can be a chore to keep it alive to flower. This article will explain a little more in detail: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/hydrangea-not-blooming.htm
