light requirements for peonies and hydrangeas

Post by kmcc54 » Thu Jul 22, 2010 4:24 pm

I would like to plant peonies and hydrangeas on the Eastern Shore of Virginia. I am not sure of the zone. Can I plant these in full sun in this zone? Also, once lime is added to the soil how long does it take for the flower color to change from blue to pink? How many applications are needed. Any help would be appreciated. Belle Haven, Va

Peonies will do very well planted in full sun in your area, but you may want to provide some afternoon shade for your hydrangeas. Changing the flower color of your hydrangeas from blue to pink is a matter of making aluminum less available to the plant by increasing the pH of the soil. It is apparently more difficult to change the flower color from blue to pink than it is to change it from pink to blue. Here is a link that describes this process very well: http://www.hydrangeashydrangeas.com/colorchange.html. I'm not sure how long it will take but I know it will be a gradual process. Good luck!
