As you know, we have 2 Blueberry bushes inside our fruit cage. They are about 4 years old and produce enough for us to snack on and occasionally bake with. Blueberries are acid loving plants but our soil is alkaline. For their first 2 years they were grown in supposedly acid based soil (the kind you buy for rhododendrons, azalea's and heathers). I tested this soil at the end of last year and guess what, it wasn't particularly acidic.
So taking the bull by the horns - so to speak - we decided to risk growing them in our soil. Last year (their first in our soil) they looked decidedly sick, pale etc. It was so wet they produced little fruit but enough. I also pruned them incorrectly to keep them manageable but know I know how to do it correctly. This year, having been fed seaweed as well as iron based feed designed to keep hydrangea's blue rather than pink, they are looking much healthier. They have cropped better but have not produced a particularly heavy or large berried crop.
In the west of the county of Norfolk, just outside King's Lynn, at Fairgreen, there is a blueberry farm, where their soil is acidic. This morning, we went to pick some ready to freeze for winter. Here is where they are Blueberry Farm
We picked 2 punnet's (we took one up for DS. & FDiL.), which weighed in total 2 1/4 kg, at a cost of £10.95 - they are £5 for a 1kg if you pick them or £7 per punnet if ready picked. You can also pick by the bucket. I think we were there for around 1/2 an hour. 500g in Tesco, sells at £3.75, organic ones even more. That amount in the shops would cost anywhere between £16 and £26, depending on whether they were organic or not.
Size wise, their berries - on the left - are huge compared to mine and slightly sweeter, but if baking with, we don't mind our more acidic ones.
