I have a male persimmon tree with one successfully grafted branch, which has about 20 persimmons on it, ranging from mushy to green. I have a bear and raccoon problem - in that I expect that they will tear that one lone branch off the tree to get the persimmons. They destroyed the bearing branches on my other persimmon last year but it is a female and is growing back. My question is: I plan to snip all the persimmons off the branch. Does anyone know how to ripen those that aren't ready to eat yet? Maybe on a windowsill like tomatoes? BTW, they're American, not Asian. Any help would be appreciated.
