fertiliser advice

Hello I was wondering if
anyone could give me some advice about feeding fruit trees and shrubs... oh and
rhubarb. I am lumping things together because I have read (online) that
10-10-10 should be good for soft fruit (although I appreciate they might not all
have exactly the same needs) and rhubarb. However googling for a source of
10-10-10 suggests that it's not that easy to get hold of, unless I am getting
the wrong end of the stick about it. (Is it maybe not available in the UK?)
Should Growmore be ok or should I go for something different. Ideally I would
rather not go down the bone, blood etc. route - I am a longstanding
vegetarian...
I have the following:
gooseberries
black, white and redcurrants
jostaberries
raspberries - summer and autumn varieties
loganberries
All of these are in the ground.
Rhubarb - in a raised bed - although the raised bed was been
placed straight on the ground.
Dwarf cherries in large pots.
All of the above are at least 2-4 years old.
Last year I think I just used some generic general fertiliser
(may have been Growmore - it's down the bottom of the garden in the shed right
now, and it's late and dark, and it's very squelchy down there, so I can't go
and look ) and things have been ok, but last year the rhubarb and raspberries
were not brilliant... although I realize that this may have been as a result of
the hot summer and me not watering things enough. (Plus I let some bushes in
the vicinity of the rhubarb get too big and overshadow them - now cut back.)
Apologies for such a long post!

Yes manure is fine. I'd like to be organic, so works well for me. Will see if I can source some locally. I just spotted a thread asking where it can be obtained in the area I live in on this forum.
I suppose I should be paying most attention to my potted cherry trees.
