I moved into my house about 4 years ago so I inherited a number of shrubs one of which is a climbing white hydrangea which produces massive flowerheads but only blooms round the edges of the flowerhead and the rest doesnt bloom at all.Any new growth is coming from old wood which is extremely gnarled.There is lots of new growth coming from all the old wood and the whole plant looks very healthy.It has had bone meal dug in round the base,granular and liquid tomato food at different times and has been checked for vine weevil.I have always allowed it to die back over the winter. I have never pruned it.it seems to me that it is using a lot of energy to produce many healthy shoots and flowerheads but doesnt seem able to bloom fully. Please can you help? Sorry I can't upload a photo.

There are varieties of hydrangea that have been developed to bloom only around the edge of the flower cluster. Sounds like you have one of these varieties.
