Paw Paw genetics, persimmons, apples, black walnut questions.

Only 1 of my Paw Paw seeds from Baker Seed Co. has survived.  A co-worker gave me a Paw Paw from a grove near his house and I have those seeds stratified in my fridge.  Do I need to get a fruit or start from another location to enhance my chances of getting fruit some day, or will I be ok with what I have?  

I missed out on finding wild persimmons this year, hope I have better luck next year so I can start some Persimmons.  Definitely going to have to protect them better than I protected my apple saplings.  The deer stripped them bare.  I'm hoping that they come back next year, but not expecting it.  

There are no Black Walnuts on our property but I did find a few nuts from another location.  Do I need walnut trees with different genetics in order to have productive trees?  I'm going to be planting these down the hill from our house near the area where the wet weather stream runs through.  That will keep them well away from areas we will be planting any crops and put them in a moister environment.

With deer, squirrels, birds, and wild turkey in the area I know there will be a lot of competition for fruit and nuts.  I don't mind sharing, in fact one of the reasons for planting Paw Paw, Persimmon, and Black Walnut is to attract and feed wildlife.  I just hope they leave enough for us!

I wonder if you take a walk on a trail in your area and then look for scat...what you would find.

Right now in my area, I regularly find deer or bear scat full of persimmon or paw paw seeds.

I foraged some black walnuts and left them in driveway so the outer hull would come off. Behold, squirrels found them, stole them, and buried them and now, a few years later, I have black walnut volunteers popping up in unexpected places.
