Question
my son gave me a hydrangea for easter  but now it look like it is dying  because  the  flowers are   faded  zone 9

Answer
Your fading Hydrangea is fine -- it just needs a rest.  Your Zone 9 climate is perfect for growing the more tender florist Hydrangeas.

Do you know how to repot this plant?  Find a pot -- preferably Terra Cotta -- one size larger than the pot it's been growing in, and fill with good, healthy potting soil, enriched with compost.

Now get a large empty juice container, preferably plastic, NOT one that has ever been used to hold milk or other fatty beverage.  Fill that container with water, and add a teaspoon of White or Cider vinegar.  Mix well.

This is a perfect ready to use highly acidic watering solution for watering your Hydrangea.  Keeping the soil acidic will ensure that next year's blooms will still be blue.

A dose of Nitrogen fertilizer would also be appreciated by the leaves; Phosphorous would be used by Roots.

Good luck with your plant.  Any questions, I'm here.
