Efficient gardening has been put into simple terms at Bungowannah's Wrenwood Farm during the final days of the Albury-Wodonga Sustainable Living Festival.
Owners Jayson and Lizabeth Souness walked people through how to make wicking beds at a free workshop on Friday.
Mrs Souness said raised garden tubs made from re-purposed materials were sold at the farm shop on the Riverina Highway.
"We manufacture those here at Wrenwood, but the wicking beds is something we've come into - a lot of customers enjoy them because they're water-wise," she said.
"It makes contact with the earth that you grow your vegetables in and therefore the water continues up - that's why it's called a wicking bed.
"You can fill the water reservoir up and leave it - it's pretty much self-sufficient."
Mrs Souness said she and Jayson were proud to be part of the program of events for the 6th festival, and attended presentations at the Sustainable Activity Centre at Gateway Village, where the festival program began last weekend.
"Anything that gets you back into the garden and being more efficient on a day-to-day level is a good thing, whether you're recycling your clothing or being mindful about where your day-to-day goods come from," she said.
"The festival is a great initiative and when councils and groups get on board with this type of thing, it's amazing."
The final events of the Sustainable Living Festival take place this weekend, concluding with the grand opening on Sunday of the first housing development to receive 10 stars through the Victorian Government's Residential Efficiency Scorecard.
