Caleb Diack, of Invercargill, has been grafting walnut wood on to rootstocks and planting the saplings on his plantation near Roxburgh. Photo: Sanda Jukic, Southland ExpressNurseryman Caleb Diack, of Invercargill, is growing walnuts but does not want to put all his eggs in one basket. He scoped the area to see how well other walnut trees were growing, and also talked to growers in Cromwell before starting the project. The first trees to be planted have already produced a few walnuts, but he expected that to increase as the trees matured. In addition, walnut trees liked hard frost and hot summers, so Central Otago was ideal for them.
