Been trying to grow blueberries for 5 yrs now and have bought a few each year.
Blueberries are not native to Iowa and our soil does not have as high an acid content as they prefer.
As far as planting I started planting them in two 40 ft rows along side the briars( I will get to latter).
I treat the ground with an acid through the year, and have started using Pine straw mulch ( Think it was Lyall who told me about that. They started to produce last year.
The birds will get all the berries before you do? So I have made cages of hardware cloth to protect them.
A 3 ft length connected together with hog rings, a fiberglass electric fence post( like a dowel) and zip tie the cage to the post.
Oddly the best luck I have had with the blueberries, has been with a dwarf variety suitable for growing in pots. I have 3 in front of the house n probably bushel pots that are doing nicely,
