I have a granddaughter getting married in March and she wants white hydrangeas in her bouquet. Could you give me some advice on how to keep my white hydrangeas bushes white. Do I need to put a special fertilizer on after this season and should I prune the bush? Should I protect the bush with shade cloth when it flowers, as we have very hot weather in January/February?
