Hydrangea falling over

evelyn o flynn asked 4 years ago
I have a 4 year old hydrangea which has blossomed each year pink so this year I wanted to change it to blue which successfully worked after adding colourant. what I did notice however was these beautiful blooms have fallen over onto the ground and doesn’t look so good. Is there something I can do to prevent for next year. They seem top heavy but I have seen large bushes dotted around the country that don’t seem to have this problem.
