About Koyuki Bonsai
We started in 2009 with a dozen Podocarpus seedlings in a back garden. The nursery now holds more than two thousand trees at various stages, but the method has not changed much.
Why only Podocarpus
Podocarpus grows year-round in our climate, forgives beginner mistakes, and develops mature bark faster than most tropical bonsai material. Working a single genus means we know how each variety behaves in each season — hard to achieve across twenty species.
Propagation and grafting
Most of our trees come from semi-hardwood cuttings taken at the start of the wet season. Blue Ice we graft onto P. macrophyllus rootstock, which roots more reliably in tropical media and holds the foliage colour stable.
Grafts are worked low, just above the root flare, then kept covered for two seasons until the union disappears into the bark. A high graft is visible forever and devalues the tree permanently.
Our position on collected material
The bonsai trade across Southeast Asia still moves a great deal of wild-collected yamadori taken without permit. For Podocarpus costalis this is not only an ethical question — the species is endangered and collection is illegal.
We do not take material on consignment, in trade, or by purchase without documented origin. Every tree in the nursery carries its propagation year and source.
Before a tree is offered
A tree we release has usually had at least five years of work: nebari development early, then trunk movement and taper, then branch ramification. Nothing recently repotted is offered until the roots have fully recovered.
