Yes, you can propagate the Gingko from cuttings. Using rooting hormone, keeping the medium damp and making a plastic 'greenhouse' covering it may take about 8 weeks more or less. You should always take more cuttings than you need as some may not cooperate. If you end up with extras there is no problem sharing them later with fellow gardeners in your area.
My personal preference is to use the Forsyth Pot method.
