RE: Evergreen soil preference? Any experts.........
Yep- acidic soil (5-6 ph) and moist soil.
Pines tend to grow a bit faster than spruce, and handle a wide variety of soils - White pine grows well on our acidic, clay/loamy soil.
Note: if you ever plan to plant along a road in the north - remember that White pine is Highly Salt intolerant - and will suffer when planted near roads that get salt & are plowed - Austrian Pine is much mure tolerant.
