Why Is My Palo Verde Tree Oozing Sap?
Is sticky amber sap coming out of your Palo Verde tree? Have you noticed wet streaks, gummy spots, or sap around a crack in the trunk? These changes can be worrying, but sap alone does not mean your tree is dying or has borers.
Sap may appear where bark has been injured by pruning, sunburn, birds, or other damage. The important question is what caused the opening and whether the surrounding wood and canopy are healthy.
Warner at Warner's Tree Surgery has been working with sick trees since he was 20 years old. He examines the symptoms and growing conditions before recommending care.

What Can Cause Sap on a Palo Verde Tree?
Bark injuries and pruning wounds
An opening in the bark can allow sap to escape. Look for a nearby pruning cut, scrape, broken branch, or other visible injury. Photograph the area without picking at it or peeling away the bark.
Sunburn after heavy pruning
Removing too much canopy can suddenly expose previously shaded bark to intense Arizona sunlight. Sunburned bark may discolor, ooze, crack, or become sunken. Avoid removing more healthy canopy while the cause is being evaluated.
Bird activity or other small wounds
Bird pecking and other bark injuries can leave places where sap appears. Small holes need to be examined in context; a hole or sticky spot by itself does not identify the cause.
Other problems that need closer inspection
Persistent oozing accompanied by spreading bark damage, dying branches, or canopy decline deserves an examination. An inspection helps distinguish a localized wound from a more serious problem.
Does Oozing Sap Mean My Palo Verde Has Borers?
Not necessarily. Sap is not enough to confirm an insect infestation. Palo Verde root borer larvae feed underground, so a gummy spot on a branch does not establish that they are present.

What Should I Do Before Warner Visits?
- Take a close photograph of the sap and a photograph of the entire tree.
- Note when the oozing started and whether the tree was recently pruned or damaged.
- Describe any changes in leaves, branches, irrigation, or nearby landscaping.
- Avoid cutting into the trunk or applying pesticides, fungicides, or wound sealers without a diagnosis.
- Keep people and pets away from a cracked or hanging limb. Do not stand beneath it to inspect the damage.
Can a Palo Verde Tree With Sap Be Saved?
A small area of sap does not automatically mean the tree must be removed. The outlook depends on the cause, the amount of damage, and the condition of the whole tree. Warner can explain what he finds and discuss appropriate next steps. Recovery cannot be promised without examining the tree.
