winterizing my hydrangeas
I have just bought a new home and in doing so have adopted a yard full of landscaping - mostly perennials and including hydrangeas. I have never gardened but look forward to the new hobby!! So, I have no idea what kind of hydrangeas I have but they are large, white and beautiful. Very few are browning. The big question....what do I do to prepare/protect them for winter? Do I cut them back? If so, when? Do I leave them - let the flowers brown? Do I need to mulch? If so, when? After the first frost?
