I’ve written many a blog and social media post about why blue hydrangeas don’t flower. You can read one of them here. But I’ve always had it in mind to put this in a graphic form, and today was the day! You can get a printable pdf of this graphic by clicking here.
I have another problem with my blue hydrangea. It used to have large flowers and now it’s flowers are half the size they were. Should l thin out the canes? Does it need fertilizer? Help please.
Compost over the area this fall, then fertilizer next spring and a good deep soaking once a week if it doesn’t rain. Don’t skip the compost!
