The four contenders will vie with around 1,000 rivals from 50 countries in categories across six sectors including construction, manufacturing, IT and fashion.
The WorldSkills event is held every two years to benchmark training standards from around the world and create an internationally competitive workforce.
Grant Finch, 19, James Cuffey, 20, and Simon Abbott, 21, study at Askham Bryan College. Oliver King, 21, is training at Otley College.
Finch said: "This is a great opportunity to showcase what we do and highlight how skilled landscape gardening is."
Lifelong learning minister John Hayes, who announced the young landscape winners recently, said they would join a UK squad with other professionals. "Visitors to the event will discover how skills shape our world," he said.
