Looking for a bit of advice - I have a blueberry plant given to me by my mum a couple of years ago. Year 1 we had 2 blueberries on it - I gave it the benefit of the doubt and thought it just needed to mature a little! This year again only 2 berries no signs of real life other than leaves etc.
So what do I do?
Should I repot in spring?
Should I cut it back at all? How much - where to?
Is there anything I can do to boost fruit production?
This will be it's last chance! One of my neighbours has a similar sized plant which produced bucket loads of fruit this year and last 
I am a bit harsh on plants - if they don't produce something edible they don't get planted/ survive apart from a couple of roses we have moved with us. We move frequently (2 yrly ) because of my job, always in a rental property where gardens take me 2 years to "sort out" then we move again so have a policy if I am spending money on a plant for garden it needs to give something back i.e. food. Once I retire and we get our own house then I will do the flowers for aesthetics bit as well 
Thanks in advance for any advice
