What aphids does
Aphids suck sap from Park City deciduous trees, causing leaf curling, discoloration, sticky honeydew, and reduced vigor.
At Park City elevation, stress factors such as drought, compacted soil, warm winters, heavy snow years, and poor irrigation can make trees more vulnerable. Treatment works best when the pest is identified early and the timing is right.
Symptoms to watch for
- Leaf curling, sticky residue, discoloration, thinning, or premature drop
- Browning needles or branch dieback
- Small holes, pitch tubes, sticky residue, or trunk damage
- Declining vigor after hot, dry weather or hard winters
Greenleaf treatment approach
Systemic soil injections and topical sprays depending on severity. We inspect the tree, confirm the pest or stress factor, then recommend the least excessive treatment that can realistically help.
