Paw paws like to be grown as an understudy tree (inside a forest)
rich soil like found in river areas .
They grow wild here , but I have not herd of them grown that far west
You might consider trying to find the fruit and eat some before going to all the effort of growing. It is an acquired taste , I like but most of the people I know do not.
I have only eaten the fruit fresh , It is full of large seeds and a bit difficult to eat.
the wild trees around here do not produce an abundance of fruit.
