My orchard soil ranges from 5.0 to 6.5 ph.
I have my orchard on a slope and fine dirt has washed down the hill side
for who knows how many years. So I have about 2 feet of good dark soil with red clay
underneath.
I learned years ago that figs seem to like slightly acidic soil so I haven't added lime in years.
I take a couple cups of soil, add water to mix then let dirt settle out.
I use a ph test strip and test that water. It gives me a good idea of my soil ph.
So I put the blueberries in the 5.0ph soil and figs in the 6.0ph and up.
Figs are very adaptable in many kinds of soils and ph does not seem to be a factor
I worry about much any more.
