|Two years ago, I bougght a Gingko tree. Since then, a shoot from the base has grown to a height above the original. The leaves appear to be some type of Gingko, but are larger and are split to almost the base of the leaf.
Is this from a graft or what?
|Ginkgo trees are either male or female and because the females produce odorous fruit, most trees sold are males grafted onto vigorous rootstock. I suspect that the shoot has emerged from below the graft and is representative of the rootstock, rather than the grafted variety. The foliage of all ginkgo trees is similar, but can change with age. It sounds as though the rootstock is more mature than the graft and is therefore producing slightly different appearing foliage. If the tree were in my yard, I cut back the shoot that developed below the graft and maintain the grafted tree.
Best wishes with your landscape!
