Up in New England... The wild blueberry shrub doesn't get much more than a foot tall.

Seems like they aren't real particular about nutrients.

Soil and Site Characteristics: Coarse textured glacial outwash deposits form a flat to undulating substrate that can encompass a wide moisture gradient. Xeric conditions on hummocks or raised areas can grade into bog-like vegetation in depressions. Soils are highly acidic and nutrient poor.

In my area... high bush blueberries are found up on the slope where the seep springs are,
What kinds are you planting?

Have you checked with the extension service?
Not finding a lot of information online specific to montana...
Seems like ph level is going to be more important than soil fertility, or removing clay...
