Senior teacher Rosezana Tutty said the Blossom Festival has been a highly anticipated event for the children.
"They're very excited and they've been counting down the days and asking us when it's coming," she said.
Dressed as flowers and insects, the 25 preschoolers walking in the parade will be joined by their parents who will push and pull them in decorated wagons.
Preschool director Joelle Pretorius said parent involvement in this year's festival preparations has been great.
"We've had good parent involvement in preparations and parents coming along to walk. They should have a lot of fun," she said.
The children are set to make a colourful impression on spectators and won't be missed with newly designed Future Kids Preschool T-shirts in bright blue, green, orange and pink.
Mrs Pretorius said the festival was a great chance to raise the preschool's profile in the local community.
"We really want to raise our profile in the community. Spring is all about life and vibrancy and these kids are just blossoming."
With the forecast predicting heavy showers throughout the day Mrs Pretorius wasn't taking any chances with the cold and potentially wet weather.
"We've sent out parent letters so the kids will come dressed warm and we can put the T-shirts on over the top but if it's wet we won't be able to do it," she said.
The parade will begin at 11am today on the corner of Lyndon Rd and Hastings St and will finish on Russell St.
