Mrs Blackburn said that in the past year "and with the help of an amazing team of pupils, parents and grandparents, we've grown around 4000 plants and have just started seeding vegetables, pots of colour and a variety of flowers".
She said, as in previous years, the plants have been sourced locally, donated by friends of the school or by people who had connections to the school.
The garden gala is one of the school's biggest fundraisers for the year and a true community event.
New to the garden party this year will be the inclusion of garden art made by some of the school parents, as well as furniture made from wooden pallets.
Returning will be the cut-flower arrangements stand and "pop-up" cafe in the school hall, with pupils selling home-made baking and treats.
Eftpos will be available on site at the cafe and to purchase plants.
Mrs Blackburn said that, over the years, the reputation of the pop-up cafe had grown and the pupils clamoured to help run it.
"I am thrilled to say it's back again this year, selling fresh home baking, tea, jams, pickles and chutneys.
"There will also be a coffee cart, live piano music and a grocery raffle - so something for everyone," she said.
The garden party plant sale will open at 8.30am.
