If blueberries and azaleas are happy in your yard with no amendments you likely have acidic soil.
I spread lime (from lowes) on my garden spot in the early spring, just because LOL.
YMMV of course.
I’ve also used the azomite stuff.
My souls are not very acidic, according to my mom. She is 80 and had both knees replaced so she purchased a tower garden contraption. She’s constantly harvesting veges from it. She is down in Savannah, GA.
