It may have been a seed planted. No, there is nothing you can do to change the fruit. Do you own your house? if yes plant your own fruit trees. You can grow great fruit in SC. Peaches are great there. Also peaches give fruit younger then pars or apples. But buy a good variety, bare root in the spring. Choose your variety based on what you read here or learn from a professional grower in your state. There is alot to know to be successful, so don't just plant it and ignore it while you wait fir it to grow up.

If the tree is unmanaged, there are things you can do to improve the fruit.

You can thin them out in the spring when they are very small. The remaining fruit will be larger and better quality.

You can prune the tree for better light penetration and air circulation.

You can graft one or more excellent varieties onto it.

All things that might be more gratifying on your own tree if you have the space. You can practice on his for a few years until yours comes into bearing. Then you can share your fruit back.

OK. Thank you. I have quite a few trees planted since 2010 of varying kinds and haven't seen fruit yet. But the trees all look OK. Asian pears and plums bloomed beautifully this year, but I think we had a late frost that killed all the buds. No fruit. So I've been looking to scavenge from other sources while mine get going. :-)

Thanks again.

I think I love "sand pears" - hard, crunchy & watery-juicy sweet! Where's a good source to buy them at?

you could bud graft from the sand pear onto your existing pear and see how it goes
