Monkey Puzzle Tree Trunk Fissures: Arborist Evaluation Needed

Two 40-ft monkey puzzle trees in yard. Both develop southwest-facing trunk cracks (front: 2 ft up, 3 ft long, 6 in wide, white ooze visible; second crack forming above; back tree: smaller basal crack). Owner fears failure.

Critical Questions

When did cracks appear?
Overall canopy health?
Other bark damage near soil line?

Immediate Steps

Submit photos showing full crack length.
Hire certified arborist (yellow pages → tree services → verify certification).
Contact county Extension for possible site visit.

Risk Factors

Large conifers with structural cracks near homes require professional hazard assessment. Internal decay, lightning, or structural weakness possible. Bird habitat value noted but safety paramount.
