Preventing Ginkgo Fruit: Not Really Possible

No practical treatment prevents flowering/fruiting on female ginkgo. The only management:

Collect fruit daily when it drops (before it rots and smells).
Plant male cultivars only ('Autumn Gold', 'Princeton Sentry', 'Saratoga')—grafted, guaranteed male.
Cities ban females for the stench (butyric acid in rotting fruit).

Why No Chemical Control

If you have a female: rake daily in fall. If planting: buy male cultivar.
