But it isn't just about teaching their offspring about where their food comes from.

Emily and Tim Baitch's nine-year-old son Charlie is on the autism spectrum and they wanted to introduce him to an activity where he could develop skills he could use in a future career. Charlie's desire to one day drive a tractor also helped to push them in this direction.

A generous neighbour who offered the family a portion of their large block for the venture sealed the deal.

"Whether it's in the selling process or the growing process, we wanted to teach him some skills," Mrs Baitch said.

"We got him to come and do specific jobs. For example, first we do some planting and then we go back to the swing. It's about building his skills in a way that he can be outside and moving.

"It's a reward system where he would either do some planting, harvesting, pruning or watering and then we'd go and do some swing time or have a snack or something like that."

Charlie's siblings Monty, 7, and Annabel, 4, also help in the garden.

"The main aim is to enable him to develop skills so that when he is 18, when he is ready to get a job, there is something that he can do. We want him to be a useful member of society," Mrs Baitch said.

"When we go over there we take them all over. There is a job and we do it, and once it's done they can go back."

Mrs Baitch and Charlie attended their first Slow Food Earth Market in The Levee last week, with his school's blessing. Charlie attends Our Lady of Lourdes Primary School in Tarro and is encouraged to participate in a community activity.

Their fresh vegetables were so popular that they sold out in just over an hour.

"The shop part of it is about him being able to chat to the customers. He found out everyone's name, he said thank you to everyone," she said.

"[The garden is] green. I plant things, I use the watering can, we plant celery, beetroot," Charlie added.
