Ginkgo Tree Half Leaf-Out: Woodpeckers or Water Issues

Ginkgo in Chicago with leaves only on top half, woodpeckers present: woodpecker holes in lines rarely kill but can disrupt flow if extensive. Overwatering causes root dysfunction and bottom-up leaf loss.

Assessment

Check trunk for rows of small holes (sapsucker).
Assess soil moisture: soggy = overwatering.

Action

Fertilize with tree spikes.
Adjust watering: deep, infrequent.
Monitor 2 weeks; report changes.

Ginkgos are tough; usually recover with corrected culture.
