I've heard people say to push a nail or two in the ground near the bush and that will change the color of hydrangeas. I've never done it as I never had hydrangeas. But two years ago I planted climbing hydrangeas close to our newly-built pergola and am wondering what anyone thinks as to what I can use to make them grow faster! They're awfully slow growers, aren't they?
