Hydrangea - advice please

I can only pass comments on what I have observed with the ones I have, so I hope this is of help. Perhaps others could chime in on this also.

A lack of blooms could be down to a number of things.

First, the frost gets at them. They do seem to prefer cooler, partly shaded positions. I suspect that this is partly because these places are also sheltered, and therefore keeps frost damage at bay. As @Verdun says, they like moist conditions and the shade also stops them drying out.

Second. Never, ever feed hydrangeas! Feed promotes faster growth, and ones that grow quickly do not bloom. Do give them regular doses of organic material. I use compost or turf

 

Hi I have to be honest ive not really done anything with them I have no idea what im doing they get plenty of water same soil one flowers the other nothing! Should I prune it or something. Sorry for sounding so dim

 

One looks to be in gravel katie....? Or has a gravel mulch?
No, dont prune now.
I would give the non flowering one.....(by the way, it could still flower this year. May be later flowering. Different varieties behave differently). ......a mulch of dried manure or chicken pellets mixed with compost
Could you post a picture of the two together? ...you said they are in the same soil.

 

Yes they are in the same soil just a few feet apart the pics aren't the best they dont have gravel thats some pots thats in the picture they are both covered in bark chippings, i use a multipurpose feeder every couple of weeks. I'll tru het better pictures today it's raining now thanks
