About this episode

The episode explores the efforts of a local tree crop association in Dunedin to identify heritage apple varieties and a propagation scientist's work in Rotorua on growing native trees from cuttings.

In Dunedin the local tree crop association has been looking after a heritage apple orchard, but some mixed up labels meant they weren’t quite sure what varieties they had. A chance encounter at a public open day sets one young researcher on a scientific quest to ID them all. Plus, in a nursery in Rotorua, a propagation scientist is figuring out the best way to grow a native tree from cuttings. Go to this episode on rnz.co.nz for more details
