My Hydrangea Suddenly Turned Blue!

I planted my first hydrangea bush about six years ago. It was a purchase that I had made on a whim from an online supplier. When it actually arrived, the plant was less than 6 inches tall. It took a few years before it finally bloomed. Though the plant had been advertised as pink, the flowers in my yard were actually purple. This was due to neutral pH of my soil. I’ve had lovely purple blooms every since – until this year.

As you can see, this year’s blooms are a very true blue color. This would indicate that my soil pH has become much more acidic over the past year. Since I’ve done nothing to change the pH, I’m only left to wonder why such a change did happen.

My best guess related to soil pH relates to my neighbor’s use of liquid chemical fertilizers. Since my hydrangea bush is located directly next to the property line, I’m thinking he may have applied something to his own plants on the other side.

Either way, I’m not disappointed. The bright blue color is very lovely. What do you think? Have you ever had a hydrangea bush suddenly change color? I’d love to hear all about your experiences in the comment section below. Thank you so much for visiting the blog!
