Ahead of their annual 'family fun day' on October 31, the greenhouse team has grown a bumper crop of seedlings for sale.

"We have a prolific gardener, he's addicted to making things grow," said Ben Holt, educator at the centre.

Aided by the recent installation of a solar-powered watering system, Mr Holt describes the garden as "thriving" with "hundreds of seedlings", including up to 50 kangaroo paw plants, which in Mr Holt's words, "that's a lot".

This year, the annual event has been given the theme 'a safe day out with the family', referencing the pandemic's impact on group activities this year.

"This will be one of the first community events coming out of the COVID restrictions," Mr Holt said.

"It's a celebration of easing as well as a time to get out in the gardens. There are good things happening in our community still."

Across the 5000 square metre gardens in Turvey Park, the team will be hosting scavenger hunts and nature play activities.

"There will be two workshops throughout the day, a coffee van will be there, we'll have homemade cakes to sell and then our mega plant sale as well," Mr Holt said.

"[The gardens] are a safe place for children and families to explore, full of intrigue, and a pretty unique thing to have in the middle of Wagga."
