I live in zone 4 and planted some pee gee's this spring. The crop farmer behind us sprayed his soybeans and it spread onto our hydrangeas! I've clipped them back and have added miracacid to them. What else can I do to prepare them for the winter hoping that they will come back in the spring!!

Hi Klappster,

I realize that I'm probably a little late to help you with your question, but here's a site that should be helpful.
