Q.Hydrangea and Pests
My hydrangea does not bloom each year. I was told changing soil would help the color of the plant to change. Is this true? How do I get my hydrangea to change color, and why doesn’t it bloom every year? How do I keep rabbits and deer from eating my new plants, such as lilac trees?
