My hydrangea is growing wild, it is a huge bush, but there are almost no flowers. Why and what to do?

It sounds like it needs cutting back. This will thicken the bush and should produce flowers next year,

They are not blooming this time of year. Don't do anything. They will bloom on the growth from this year so next spring/summer you should have a good amount of blooms.
