Indoor Hydrangea Care

I have a Shooting Star hydrangea that I brought in for the winter. The room has indirect light and is cool. The leaves are turning yellow. Is this normal and will it survive the winter? Thank you.

The leaves are turning yellow due to the fact that it is trying to go into dormancy. Hydrangea really need to go into dormancy for a few months to be healthy. Do you have an attached garage or basement - basically somewhere relatively cool and dark - you can place it in for a few months to do that? Once there, it will lose all its leaves. Water it once or twice a month and bring it back out in the spring.

Shooting Star Hydrangea Not Blooming

I have a shooting star hydrangea that I bought in a small pot at Whole Foods. I planted it in my yard in morning sun, afternoon shade; and while it grows nicely each year, it has not bloomed since planted. I also fertilized in spring when new growth started. I have not pruned it, not knowing if it needed the old wood. Any ideas?

This is most likely a Nitrogen issue. To much Nitrogen will cause lots of leaves but no flowers.
Phosphorous can be added to promote flowering. Bone Meal is a good way to do so.
