My parents have a medium size peach tree they started from a peach pit.

A clonal 'Bing' is grafted. Seeds are not true offspring of clones. That's what you can tell your Dad.

Growing from seed is an adventure. The offspring are much less likely to produce a better or equal tree to the cultivated/grafted selection the seeds came from. However, that's how better selections are found. Someone planting seeds with a lot of patience to wait for those first fruits to bear.

in my yard.. they get started.. right after i open the package and plant the named variety i bought... lol ...

at 91 ... the obvious answer is.. let him have fun.. and enjoy every minute of it ...

or.. order in a transplant .. and have him plant it ... its about that time of year to be planting dormant trees ... though i am unsure of such with fruit or your area ... spring might be better ...

if you are interested in such .... ask in the fruit forum for favored vendors ...

it might be the best 30 to 50 bucks you ever spent.. to see him plant it ..

ps: there is also the question of the odds that you will get a BING cherry from a random BING seed ....
