Starting out with not much more than your average suburban Dutch garden plot, with the citrus in just one corner. We have eyes on the neighboring plot that would give us more than a hectare to play with. But first we need to convince the owner to sell :)

There are also fig-growers groups on FaceBook, where lots of trading goes on.
