Arizona Ash: A Guide to Growing and Care
Introduction
The Arizona ash, also known as desert ash, smooth ash, leatherleaf ash, velvet ash, or Fresno ash, is a beautiful and stately tree that can add beauty and shade to your landscape. It is native to the southwestern United States and some areas of Mexico, and is well-suited to growing in USDA plant hardiness zones 7 through 11.
Description
The Arizona ash is an upright, stately tree with a rounded canopy of deep green leaves. It is relatively short-lived, but may survive for 50 years with proper care. Arizona ash reaches heights of 40 to 50 feet (12-15 m.) and widths of 30 to 40 feet (9-12 m.).
Young Arizona ash trees display smooth, light gray bark that turns rougher, darker, and more textural as the tree matures. This deciduous tree provides great shade in summer, with bright golden-yellow leaves in fall or early winter depending on the location.
Growing Conditions
Arizona ash trees are relatively easy to grow and care for. They prefer full sunlight, but can tolerate partial shade. They are also drought-tolerant, but perform best with regular water during hot, dry weather. Arizona ash trees can grow in ordinary soil, but prefer well-drained soil that is rich in organic matter.
Planting
When planting an Arizona ash tree, choose a location that receives full sun or partial shade. Dig a hole that is twice as wide as the root ball and just as deep. Place the tree in the hole and backfill with soil, tamping down gently to remove any air pockets. Water the tree deeply and regularly until it is established.
Watering
Water young Arizona ash trees frequently, especially during hot, dry weather. Once the tree is established, it can tolerate drought conditions, but will perform best with regular watering. Water the tree deeply, allowing the water to penetrate to the roots. Avoid overwatering, as this can lead to root rot.
Fertilizing
Fertilize Arizona ash trees once a year in the spring or fall. Use a slow-release fertilizer that is designed for trees. Follow the instructions on the fertilizer label for the correct amount to apply.
Pruning
Arizona ash trees rarely need to be pruned. However, it is a good idea to remove any dead or diseased branches. You may also want to prune the tree to shape it or to remove any branches that are rubbing against each other.
Pests and Diseases
Arizona ash trees are susceptible to a few pests and diseases, including aphids, scale, and fungal diseases. Aphids and scale can be controlled with insecticidal soap or horticultural oil. Fungal diseases can be prevented by watering the tree deeply and regularly, and by avoiding overwatering.
