What's eating my ginkgo 'fastigiata'?

Ginkgo biloba 'Fastigiata' is remarkably pest-resistant compared to most trees. The primary threats are occasional aphid infestations on new spring growth and, in some regions, Japanese beetles that skeletonize leaves in midsummer. Deer rarely browse mature ginkgos but may nibble young saplings in winter.

Curling or distorted young leaves in spring; sticky honeydew and sooty mold on foliage Knock off with a strong water jet; apply insecticidal soap or neem oil if populations are heavy; encourage natural predators such as ladybugs

Skeletonized leaves — tissue eaten between veins leaving a lacy appearance — from late June onward Hand-pick adults into soapy water in the morning; apply neem-based sprays as a deterrent; avoid pheromone traps near the tree as they attract more beetles

Ragged browsing of young shoots and lower branches, especially on newly planted trees Protect young trees with wire mesh cages or tree guards in the first few years; once established, ginkgos are largely left alone
