Hi All. You were so helpful last week when I posted, I would like to ask
your advise again!

I have a miniature blueberry bush - Vaccinium corymbosum 'Northsky' - on
our balcony. I have had it around three/four years and it seems to
flourish, and each year produces a mass of flowers, but it never fruits. It
is supposed to be self fertile, so not having another plant isn't the
problem here.

I suspect it may well be. Allegedly self-fertile hides a multitude of
sins. And it may not be the named cultivar on the label.

Obtain a small cutting off someone elses blueberry and put it in a vase
of water nearby if you don't have space for a pair. We used to do this
to get our lonely pair tree to set fruit before it had a mate.

We live in N. Derbyshire, the balcony is south facing, so it
gets plenty of warmth and sun during spring/summer months. It is in full
flower again at the moment but I know they will just fall off and that will
be it - no berries! Any thoughts would be much appreciated! Thank you!

If it is still in flower try a soft paintbrush to pollenate them and/or
find a piece of another different cultivar in flower at the same time.

Regards,
Martin Brown
