A project to regrow gardens and orchards lost in Tasmania's January bushfires is taking root.

Plant-Aid has held workshops with experts from the Royal Botanical Gardens to help residents who lost their homes and gardens in the fires.

Marcus Ragus from the Botanical Gardens says regrowing plants is an important part of people's spiritual recovery after bushfires.

"It's shows that there is life after the destruction and nothing better than community plants and growing fresh material for actually eating later something that will actually help them in the long term," he said.

The revegetation program will share in $1.3 million from the Red Cross bushfire appeal donations.

Kerrie Brown from Dunalley's Neighbourhood House says bushfire victims have been offered free advice from Botanical Gardens experts and Hobart residents are also chipping in to grow plants.

"We're left with pretty much a sad black charred landscape with no colour in it at all in many places so I think it will be really nice for people's well-being, health and well-being to get back in their gardens and see that regrowth."
