The nursery behind a variety change

How Geisha spread across the island, one seedling at a time.

The nursery behind a variety change

Slow math

A new variety takes three years to fruit and five to judge. Most farmers hedge by planting a few rows and keeping the old trees.

That is why variety changes here take a decade, and why a single successful plot can seed a whole valley.

A variety is not bought. It is inherited, borrowed, or smuggled in a pocket.

Where seedlings come from

Few farms have a real nursery. Most swap cuttings with neighbours or buy from a district station, which is why genetics here are more local than catalogued.

If a farm can name the source of its Geisha, take that as a sign of seriousness.
