Blueberry bushes - some ripen, some don't

[Chief31]

Hi,

I moved into a house about 6yrs ago and I have 6 blueberry bushes. Three are 2'-4' tall with darker leaves, One is 5' tall with darker leaves and produces the largest berries, one is 6+' with narrow lighter green leaves, and one is 6'+ with broader green leaves. The last two bear little fruit every year, but it never ripens. A few berries may get a hint of red/purple, but never completely so. The smaller, darker leafed bushes all produce large quantities of ripe berries - I'd estimate about 2lbs each, possibly more.

I know little to nothing about blueberries (apart from the eating) - why are the taller two not ripening?

Thanks!

Have you tasted them? There is a variety called Pink Lemonade. The berries are pale pink when ripe.

The two bushes in question have light green, generally small berries. You can see in the images.

I am new to blueberries. I bought my first bush last year and got a self pollinating variety, then read that even the self pollinators produce far more fruit if they have a cross pollinator. Now, I don't know, but it strikes me as a possibility that your non-producers may be there as pollinators, much as an old fashioned fruit grower would have planted a Beauty of Bath or John Greaves, neither commercial apples, in an orchard. Just a guess.
