Should I cut off Brown hydrangea blooms?

Do hydrangeas bloom on old or new growth?
Old Wood Versus New Wood Some hydrangea species bloom on last-year’s growth, which is often called “old wood.” This old wood contains the flower buds that will open with the coming summer. Pruning in winter or spring would remove the flower buds, leaving us with a bloomless plant this year.

Is afternoon sun OK for hydrangeas?
Hydrangeas grow best in morning sun. Direct sun in the afternoon can burn the large, soft leaves. For this reason, a location where the plant gets some sun in the morning and none the rest of the day is best, but late afternoon sun probably won’t hurt the hydrangea if it isn’t in direct sunlight.
How do I know if my hydrangea is overwatered?
Root rot caused by overwatering produces yellowed leaves rather than dark, rich green leaves. An overwatered plant may shed leaves prematurely, or there may appear to be an overgrowth of green foliage due to stunted flower growth. Leaves may also grow too large, obscuring opportunities for budding.
Is my hydrangea dead?
If a stem is alive, it will display some green under the bark. If you can’t find any live stems and no sprouts are visible from the base of the plant by late spring, you have a dead hydrangea. Pull the plant out and try for a more cold-hardy variety.
