Answer: Now that your hydrangea is in its permanent spot and it has had all summer to become established, it should bloom for you next year. As for your peach tree, it should be fine over the winter months. What you want to protect are the flower buds in the late winter/early spring if a hard frost threatens. If so, simply sprinkling the unopened flower buds with water should provide all the protection they need.
Best wishes with your garden!
