Hydrangea turning purple?

I have some hydrangea (mophead) that lost all their leaves this winter. Now the buds are starting to open but the leaves that are growing are purple around the edges and now are starting to dry up and turn black. I'd like to treat the plant before the rest of the buds open, is there anything in particular I need to do and is it normal for the hydrangea to drop all of its leaves over the winter? I live in northwest florida.

I have hydrangea and live in New Jersey. They always lose their leaves in the winter and reblossom in the spring. Even though the branches and buds look like they're dying - they are not. They will bud anew in the spring. If you want your hydrangea to get bigger each year than don't cut them back, but if you do cut them back to prevent them from getting too big just keep in mind that some varieties after being cut down to ground level may not produce blossoms again for 2 years. Also, hydrangeas can be pink or blue or various shades in between depending on the pH of the soil.
Reply:I've had hydrandeas in the San Francisco Bay area and they have dropped all of their leaves. This is the time to trim them into shape. When they begin to return the budding leaves are very dark. Unless you know the actual hybrid name its hard to say but most survive cooler winters
