You also need to make sure you have the proper PH soil for Blueberries. They like a lower PH (~4.5) than most soils so you'll likely need to add sulfur and use a fertilizer for acid-loving plants. Because of this, I keep my Blueberries in containers where it's easier to control PH.
It took me a long time to dial in blueberries PH wise. I use 5ml of extremely strong phosphoric acid per 2.5 gallon watering can.
I wonder if I should buy this too, just found a supplier for it. It says its a 85% concentrate. Will pass it for now since I added sulfur two months ago....
Depends on your water PH. Mine is extremely alkaline at 8.3ph so I use the phosphoric acid every time I water AND top dress with sulfur. It's really hard to get blueberries right when your water is like mine.
My well water as far as I remember when testing was around 7 and slightly above. Okay ,I will then buy 1 liter of this ,I thought that it could make an reaction with the sulfur in the soil , but if you are using it with sulfur then I should be good too ...
Don't plant them anywhere near concrete because it leaches lime into the soil... not good for Blueberries.

when I did my blueberry bed ,I had one side of it that was next to a concrete supporting base. I just placed some nylon and fixed it with the soil, to stop the lime leeching into the bb's medium.
