Pests in Gardens and Landscapes

Maidenhair tree, Ginkgo—Ginkgo biloba
Family Ginkgoaceae (Ginkgo family)

Plant Identification

Maidenhair trees are somewhat slow-growing deciduous trees.  Leaves are fan-shaped, leathery, and light green.  They turn gold in the fall and drop.  Trees can grow up to 80 feet tall.

Optimum conditions for growth

Maidenhair trees are often planted as street or lawn trees.  Male trees are better as female trees produce messy, smelly fruit.  Trees prefer areas with full sun.  Plant in loose, well-drained soil, and provide moderate to regular amounts of water.  Established trees only need occasional water.  Remove broken, dead branches.
