Primary Suspect: Aphids

• Feed on upper leaves → curling, yellowing, premature drop.
• Won't kill tree but cause cosmetic damage.

Action

• Inspect upper leaf undersides for aphids.
• If found, apply Bayer Advanced Tree & Shrub Insecticide soil drench—systemic, season-long control.
• If no bugs, reassess (herbicide drift possible but less likely).

Don't panic; tree is resilient.
