Three bushes in sunken pots, and probably, after three years in need of a
feed. I have the usual collection of bone meal, growmore, sulphate of
potash and super phosphate. Will any, or even all of those fertilisers
serve the bushes or do I rquire a specialised feed?

You don't say if the plants are still productive, or even reasonably
healthy. Blueberries require ericaceous compost to grow well. If the
leaves are yellowing, then they may be chlorotic and need an acid feed. If
the bushes have ceased to be productive, ie, not fruiting, then they could
be encouraged to become productive again with a high potash feed, in other
words, your sulphate of potash.

I should add that I am not an expert on blueberries, and the answer I have
given you is basic. There are other reasons why a plant may have yellow
leaves (*if* yours has?), and also why it may not set fruit, even though it
has flowered. Hopefully, you will also receive advice from the blueberry
growers on this ng, who may give you a more in-depth answer - in exchange
for more in-depth information.
