Ash Tree Decline in Mesa, AZ: Can My Tree Be Saved?

Is your ash tree looking weaker each year? Perhaps its leaves are smaller, its branches are dying, or its canopy no longer provides the shade it once did. These changes deserve attention, but they do not automatically mean your tree must be removed.

Watch: Can This Declining Ash Tree Be Saved?

Join Warner at a Mesa home as he examines a declining ash tree and explains why identifying the cause comes before choosing a treatment.

What Does Ash Tree Decline Look Like?

Decline describes a tree losing vigor over time. It describes the condition of the tree, rather than identifying a single cause. Changes homeowners may notice include:

A canopy that becomes thinner from year to year.
Leaves that appear unusually small or pale.
Little new growth on branches.
Dead twigs or larger branches.
Unusual clusters of small shoots.

Tell Warner when the changes started, whether they affect the whole tree or one side, and whether your watering or landscaping changed before the symptoms appeared.

What Could Be Causing the Problem?

Irrigation problems, root damage, soil conditions, insect injury, and disease can contribute to a struggling ash tree. More than one problem may be present. Similar symptoms can have different causes, so appearance alone is not enough to select a treatment.

Is Ash Decline the Same as Ash Yellows?

The wording can be confusing. People sometimes use "ash decline" to describe any weakening ash tree. Ash yellows is a specific disease caused by a phytoplasma, an organism that affects the tree's food-conducting tissue.

Ash yellows can cause slow growth, small leaves, branch dieback, and unusual tufts of shoots called witches' brooms. These signs do not prove the disease is present. Laboratory testing may be needed to distinguish it from other problems.

There is no established cure for confirmed ash yellows. An evaluation can help determine whether another manageable problem is involved and whether testing, continued care, or removal should be considered.

How Warner Evaluates a Declining Ash Tree

Warner examines the canopy, trunk, visible root area, and growing conditions. He also considers the watering history and checks for signs that may point toward insects, injury, or disease. The goal is to identify what needs further investigation before recommending action.

What Can You Do Before the Visit?

Take photographs of the entire tree and close-ups of affected leaves, branches, and bark.
Write down your watering schedule and check whether the irrigation system is operating.
Mention recent digging, paving, landscaping, or herbicide use near the tree.
Avoid automatically adding extra water, fertilizer, or pesticides before the cause is assessed.
Keep people and pets away from hanging, cracked, or falling branches.

Can a Declining Ash Tree Recover?

Recovery depends on the cause, the amount of damage, and the tree's remaining healthy structure. A tree affected by a correctable growing-condition problem may benefit from changes in care. A tree with advanced damage or an incurable disease may have a different outlook. No treatment can guarantee that every declining ash tree will recover.
