Feeding fruit

[davholla]

I have the following in my garden:-
Gooseberries, Jostaberries, Whitecurrants, Tayberry, Raspberries, Blueberries and Apple Trees.
Should I feed them?  If so with what?

We use sulphate of potash sprinkled round the trees and bushes at the start of the season (now will still be OK).  We also mulch our trees and bushes with well-rotted chicken manure of which we have an ample supply.  That we haven't done yet, but will do before the dry weather of summer.
