Explanation:

Lue Gim Gong was a Chinese immigrant who later became an American citizen and  created the remarkable horticultural innovations which brought him the nickname of 'citrus wizard.' The most prominent of his inventions was the 'Lue Gim Gong orange' for which  he was awarded the Silver Wilder Medal by the American Homological Society. These oranges would have matured in early fall which means around the time of August or September. The new breed  of  the fruit would not frost and therefore the chances to get the vegetation ruined became less likely.
