Blueberry Plants ???

[Gary350]

Is this the correct location for Blueberry Plants?

Lowes has 2 groups of blueberry plants for sale.

Bluecrop & Blueray also Jersey & Tifblue. Package of 2. No growing information on package.

Online says seem to suggest Bluecrop & Blueray package 1 each is more suited for TN weather and it says nothing about 100°f temperatures and dry as desert in summer June to Sept. It says nothing about zones and nothing about -2°f every 20 years.

Is anyone growing blueberries? How many berries does 2 plants produce? 20 gallons will be good for us.

I think I need to plant 2 plants so I can drive the lawn mower between them when they grow larger. 8' apart maybe???
