Change Hydrangeas Color?

Did you know rusty nails can change the color of your Hydrangeas?  It’s true!  The color of your plants are dictated by the pH of the soil.  An old wives tale says if you put old rusty nails at the base of the plant it will change the pH of the soil thus changing the color of the plant.  Overall they are a very traditional plant in the south.  Remember they don’t like much evening sun or having their roots wet all the time.  Typically they don’t get trimmed unless they get too big for a particular area.  If you do need to cut them back then October or November is the best time for this.  If yours aren’t blooming yet then get ready!  It’s almost time to enjoy these beauties!
