"I go down every afternoon and water the plants."
Five of the trees were donated and he bought the rest. He said they could be expensive, but he had been able to buy some from Saturday markets.
Mr Marsh said his prime goal was to show people they could grow their own food.
"We can live with the earth and off the earth.
"I want to see kids be able to go to parks and pick out their lunch. We can live off the land, we used to."
His intention was that anyone would be able to go and pick the fruit, he said.
He said the fruit trees were a "leaving present for my home town" before he set off to Limpopo in South Africa for a six-month wildlife internship through Global Vision International.
He would leave for the internship in September and would likely end up staying overseas, he said.
The first three months consists of learning skills such as how to track animals and collect data.
The second three months involves finding and working in a position within Global Vision International.
People at the Linton Park Community Centre have been helping maintain the growth of the trees and would continue to do so while he was away, he said.
