Canberra region landowners Louise and Luke Williamson are offering people the option of scattering their loves one's ashes on their property while also sponsoring a tree that could help revitalise their land, which has been farmed continuously for almost 200 years.

They are calling it the Capital Region Memory Farm.

Their property on the Monaro Highway between Michelago and Bredbo is about a 30-minute drive south of Tuggeranong.

People can sponsor a tree at which they can scatter or place the ashes of their loved ones. A plaque can also be installed.

"We're not a retail nursery. We're not selling the trees, we want them to stay here,'' Mr Williamson said.

"We're selling the experience of coming here and planting your memory.''

The Williamsons, who have owned the cattle property since 2009, said they have already spent tens of thousands of dollars trying to reverse "the impact of the ill-suited European farming practices of the 1800s'', with the land in continuous agricultural production since the 1830s.

They want to plant thousands of trees to help provide shade and fodder, when needed, for the stock, and to improve the fertility of the soil, in contrast to the wholesale clearing of the land a century or two ago.

Following the death 18 months ago of Mrs Williamson's mother, they  were also "really shocked at the price'' to store ashes at traditional crematoria and wanting a better way to honour her than storing the ashes at a crematorium, or having them disposed.

Those two disparate problems, suddenly created an answer - the memory farm.

"Literally one afternoon, over a cup of tea, my wife and I came up with this idea,'' Mr Williamson said.

Trees can be sponsored for $1000 each, a price Mr Williamson says is more than competitive against traditional crematoria, and then the ashes laid beneath. A plaque can also be fixed to the site for another $250.

"The arrangement is, because of land zoning restrictions and things like that, we can't sell people trees,'' Mr Williamson said.

"So what we're offering is the ability to sponsor a tree. Come out to the farm, we'll give you a tour, we'll walk you through all the environmental work that's been done, if you want to.

"We'll take you out to one of the treelines, you can plant the tree, spread the ashes, if you wish. And, also, with some notice, we can put there a rock memorial, so a plaque on a rock.

"We will fence that part of the paddock out of production for five years while the tree is becoming established and from then on, periodically let the cattle in just to keep the grass down.''

The Williamsons said they would welcome people back to the farm to revisit where they had scatted the ashes.

"Absolutely. We'd love them to,'' he said.

"And, of course,  that will have no cost whatsoever.''

Mr Williamson said the 344-hectare farm sat between the Monaro Highway and the Murrumbidgee River. The middle of the farm had remnant old-growth native forest.

"Between the middle of the farm and the highway, we'll be planting non-natives, frankly, to discourage kangaroos getting killed on the highway but that will also provide a stunning visual of autumn colours,'' he said.

"So some people, we think, will just like to wave at their tree on the way past. But we know other people will want to come back regularly and we're more than happy to accommodate that.''

The family felt privileged to share the property with other people searching for a way to honour their loved one.

"Having gone through it as a family, not too long ago, we know there are many people out there who haven't been able to find the right way to do it,'' Mr Williamson said.

"So, we just hope this provides an opportunity for some of them to take up the option. We know it won't be for everyone.

"We think it's great for us as we try to rehabilitate the land, great for the environment and great for people who don't know what to do.''
