Hello, I'm new here. I'm in SE toward central PA, USA in a 6a/b zone.
I have blueberries awaiting planting.

I'm thinking of putting 3 bushes in a slightly acid 6.3Ph and adding
cottonseed meal and mulch with wood chips, in dappled shade until 10AM
then sun until 6PM and low, as in cool air flowing from a hillock down
to them but still good drainage. However, there will be no relief from
75-88 deg weather and afternoon sun we usually get in late July and
early August.

And putting 3 more bushes higher in the hillock about 45 apart, 6 Ph
soil that I will supplement with cottonseed that gets sun from 9AM to
1PM and 3PM to 6PM.

Is this a good idea or should I put them all together in either
location?

Thanks for your input.
