I have been living in suburban NY for over 25 years. I have female ginkgo tree in my front yard that has bore fruit every year since as long as I can remember. I noticed that this year, the tree did not grow any fruit. Is there an explanation to this?
Thank you so much for your time!

|Most likely, there was an interruption in the spring flowering fertilization process. Flowers must be successfully fertilized to produce fruit. This type of anomaly (on plants in general) is becoming more and more common with climate change and the huge abnormal swings in weather. The temperature might have been too cold (or too hot), a spell of rainy weather during the critical period that caused the flowers to rot, etc.
Our Minnesota arboretum is probably in a colder zone than you, but their female ginkgo trees are quite variable in fruit production from year to year.
Or maybe the male ginkgo tree(s) nearby that is needed for fertilization got cut down, and there is no pollen to fertilize the flowers on your tree.
