Q.Differentiate peach trees from nectarine trees
Differentiate peach trees from nectarine trees grown from seed. Grown from seeds, a mixture of peach and nectarine seeds. Plants are now about 3 years old. They all look alike. Please differentiate one from the others. Thank you.

Technically, peach and nectarine are the same fruit. There is literally only one gene difference between the two (which results in a fuzzy or non-fuzzy fruit). Beyond this, cross pollination only affects the seeds (the fruit of tree planted from the seed would be affected). It is only something you need to worry about if you plan on growing trees from the peach or nectarine seeds.
