Answer: Ginkos turn a buttery yellow in the fall, and so early season yellowing is probably a sign of moisture stress. Make sure that the soil around the original root ball is moist, as well as the surrounding soil so that the roots are encouraged to grow out into it. This can be difficult to do because the original potting soil or root ball may be of a mixture that dries out faster than the surrounding native soil, so you may need to dig down a bit with your fingers to see. A few inches of organic mulch such as shredded bark can help to keep the soil cool and moist as well. Finally, if the tree is in a windy location, a temporary wind break can also be useful in helping to keep it hydrated until it becomes established.
