Pawpaw pollen exchange or purchase

Looking to cross-pollinate your pawpaw tree? I have a mature, healthy pawpaw tree and want to swap or purchase pollen. I have a NC-1 with many blossoms but no way to cross pollinate. I'm located in Toronto. If your trees are about to bloom and you want to boost your harvest, let's trade or I can purchase ! Please send a message with your variety and location.
