Nurseries - with a reliance on keeping plants watered, and the public demand for new plants - could have been one of the hardest-hit in the two-year drought.

However, Paul Davidson said the demand for new trees, shrubs and plants had only grown in that time.

"People are still planting, councils still needs trees and houses are still being developed," he said.

"There aren't a huge number of nurseries around and demand is growing."

He said Bell River had grown by 20 per cent over the past two years.

He said people weren't asking for advice on what plants to buy, instead Mr Davidson said people normally knew what they wanted and would grab it, regardless of if they were after native plants.

"Even deciduous plants ... they need a bit of water at the start but after that most plants are normally fine," he said.

Plenty of people were installing more bores across the city, with Bell River utilising two.

He said it remained to be seen what impact level five water restrictions would have on the city's gardens should dam levels drop any further.
