Feeding Clematis

Hi everyone
My summer flowering clematis havent been very good this year.
Could you advise me what I need to do.  Thinking a feed but not sure what to use.

Any help will be great.

    I feed mine  in early spring with a generous handful of slow release clematis feed when I can get it, otherwise rose or tomato food is good.  If I have one that needs extra encouragement I give occasional liquid feeds of tomato food up until the end of June.

    However, the main thing is to make sure they get enough water a clematis are thirsty, as well as hungry, plants.  It probbaly got a bit stressed if you had that period of drought earlier on thi summer so, give it a good drink of 5 to 10 litres once a week in dry spells during the growing and flowering season.

    You can buy packs of 'Clematis feed'. I was persuaded to buy some at the garden centre. It hasn't done them any harm. I do water everything with Miracle Grow quite often and the amount of growth in the garden, including clematis, has received good comments. It's easy to use with a feeder on the end of the hosepipe.

    I was always told to feed weekly during growing season but to stop during flowering.  They are thirsty and hungry plants

    Can you give us more info too? What age is it? In a pot, or in the ground? If in the ground, is there other planting nearby? What is the soil like if it's in a pot?
    Lack of water is the most likely problem as Obelixx says, and the abovementioned can be reasons for that as there can be competition from plants, and in pots, they can dry out rapidly . If the clematis is struggling, feeding isn't a good idea. 
    A photo would also be very helpful  :)

    I live in west central Scotland - not where that photo is...
