What goes wrong with Platanus
| Problem | What you'll see | What to do |
|---|---|---|
| Sycamore lace bug | Leaves stippled pale and yellowing from midsummer, with dark spotting on the undersides | Damage is cosmetic on an established tree and needs no treatment; healthy trees tolerate it fully |

| Anthracnose | Young leaves and shoots blacken and die in cool wet springs, sometimes defoliating the tree | The tree refoliates and recovers; rake and remove fallen leaves, and note this hybrid resists it far better than American sycamore |
