Last summer I planted 2 Glowing Embers Hydrangeas and they bloomed beautifully all season. This spring I pruned all the old blossoms and stems way down. I realize now that was a terrible mistake! My question is what happens now? I'm hoping that the worst that can happen is I won't have blossoms this year, but maybe next. The new growth at ground level is coming in nicely. Anything else I should do?
