my hydrangea has new shoots but seems to be dying on older stems.

Question

I have repotted it in larger pot but its not flowering and the older stems appear to be dying.

Answer 1

Without seeing the plant, it will be hard to tell. What I can do is include an article to common reasons that they will fail to flower: https://www.gardeningknowhow.com/ornamental/flowers/foxglove/foxglove-flowers.htm
