Blueberries need acidic soil (they're native to the pine barrens, where they grow in pine and oak forests in sandy soil). They do need another blueberry bush of a different cultivar for pollination. I have several acres of wild blueberries and a few commercial blueberry bushes of different types. Your plant is pretty small, so it might take a couple of years to see fruit. I bought a couple of plants the size of yours a few years ago and this is the first year they set fruit...they spent their first couple of years just growing.
I don't need fruit from my little guy. I just don't want it to die! If it decides to thank me with some berries, I won't turn it down!
Its still in its pot but I gave it some fertilizer and its sprung a few new leaves, but it hasn't really grown the way I was hoping it would.
The area I live in has semi sandy soil, so maybe it'll do alright, where I plan to plant it, once its strong enough.
