American Mountain Ash

The American Mountain Ash typically grows to a height of 20 to 40 feet (6 to 12 meters) with a spread of 15 to 30 feet (4.5 to 9 meters). It has an upright, rounded crown and a slender trunk. The leaves are pinnately compound, with 9 to 15 leaflets that are elliptical and serrated along the edges. In the fall, the leaves turn vibrant shades of orange, red, or yellow. 

Growing Conditions: American Mountain Ash thrives in full sun to partial shade. It prefers moist, well-drained soil but can tolerate a range of soil types, including sandy or clay soils. It is hardy in USDA hardiness zones 3 to 6.

Maintenance: Once established, American Mountain Ash is relatively low-maintenance. It requires regular watering, especially during dry periods, to keep the soil consistently moist. Mulching around the base of the tree helps retain moisture and suppress weeds. Pruning is generally not necessary, but you can remove any dead or damaged branches as needed.
