Trees for Rocky Soils
I've moved from clay soil to a soil that is somewhat sandy but has a ton of field stone (2" to 1' in diameter is common. 2', 3', 4' and 5' boulders do show up).
I took my Paperbark Maple from my previous home and I would say the 3'x12" deep hole I dug was 30% rock.
I've heard three schools of thought.
Which would you tend to agree with?
1)The field stone is not of concern. You need to select trees that prefer good drainage and aren't sensative to drought.
2) You need to select trees with far reaching root systems so they can easily go around the rocks. Likely need to stay away from trees with fiberous roots.
3) Stick to native trees that are growing in your area with similar exposure and degree of slope.
