Dads with a green thumb are in for a treat tomorrow with Wollongong Botanic Garden's Our Backyard Festival coinciding with Father's Day.
The festival, now in its second year, also marks the first day of spring and has a full day's worth of workshops and activities to show people how to make their backyards more sustainable.
Garden curator Paul Tracey said people were becoming more interested in gardening with a sustainable focus.
"I think people are trying to save money, as the cost of food and utilities are all going up, so the event is about simple things you can do in your backyard to save water, save energy costs and save food costs."
His top tip for kicking off a sustainable garden is to start a composting system, and there are a range of demonstrations on tomorrow to help people achieve a greener garden, including creating a chook pen, planting native habitats and growing a great vegetable patch.
Kids who have left buying dad a Father's Day gift until the last minute can grab a paper kite or a potted plant at one of the craft stands.
There will also be entertainment on the day and 60 market stalls selling food, drinks and sustainable products.
Last year more than 8500 people at the event and Mr Tracey is expecting even more this year.
The festival is free and runs from 11am to 4pm.
