I have a Japanese persimmon tree with two different kinds of leaves. One part of the tree has longer, narrower leaves. Another part has fatter leaves. The part with the narrow leaves doesn't bear fruit. What's going on with my persimmon tree?
I'm often asked questions such as this, mostly about common fruit trees like apples, peaches and pears. Japanese persimmon (Diospyros kaki) scions are often grafted onto American persimmon (Diospyros virginiana)
seedling rootstocks. It sounds to me like the rootstock of your tree
sprouted and grew, perhaps even overtaking your Japanese persimmon. The
American persimmon is the one with the narrower leaves. You should
remove the rootstock sprout, but it will surely sprout again - maybe
even producing more sprouts next time. The larger the rootstock sprout
has become the more new sprouts it will produce. If the rootstock sprout
is as thick as your arm, you've got trouble. You'll have to stay on top
of the situation and remove the new sprouts as soon as they appear.
