"The industry is talking a lot about young people and it was nice to get involved in something that wasn't just talking. We've got a 16-year-old in the academy and the amount he's grown in confidence is amazing," said Frost.
"It's spoken about at every level in Homebase. We are talking about carrying it on next year without a doubt."
The Homebase Academy apprentices have spoken of their excitement preparing to build Frost's RHS Chelsea Flower Show garden.
Sean Laverick and Jordan Twivey accompanied Frost, who is creating a Chelsea garden for sponsor Homebase for a second year, to the Garden & Home Press Event in central London (13 February).
The pair will join nine other apprentices to help the Outdoor Room to build the garden, "Time to Reflect", in partnership with the Alzheimer's Society.
Laverick, 22, said: "We've got a guy on the course who's been to Chelsea and he says it's amazing so I'm really excited. I can't wait to get there and get going."
Twivey, 20, added: "I think it will be surreal to see what it's like before everyone gets there. I know Adam says he gets a bit touchy when he starts building, but I think that getting the planting plan and getting it all set up will be amazing."
Being privy to the design-and-build process involved in the garden is part of the apprentices' training, while studying for a RHS level 1 award in horticulture and working in Homebase stores.
