This spring I planted 2 grafted male ginkgo trees that were only a few years old. We had a strong storm a couple months back where a portion of the green leader at the the top was snapped by hail. It was only a couple inches that was taken. Since that time it has not grown at all in height. The second ginkgo tree that I planted has grown about half a foot since that time. Will this impact the trees ability to grow any taller? Will a new shoot occur next year or should I look to replace the tree? Currently, the tree that was hit by hail is about 4 ft tall.
