Planting Ash

Both Green and White Ash withstand winters in the northern United States. They are hardy up to and across the Canadian border (zones 2 and 3), tolerating winter temperatures that dip blow -20°F.
Ash trees grow best in full sun, but most types will tolerate light shade. They prefer a well-drained soil that is acid to neutral (pH 6.1 to 7.5) but they grow in almost any soil as long as it's kept slightly moist. Ash trees have shallow, fibrous roots that spread widely. They transplant well if their roots are balled and wrapped in burlap. Ideally, they should be 5 to 10 feet tall.
Plant young ash saplings in the spring or fall.
