In chinese we call those 'gut' meaning 'everything goes smoothly' (can't think of a singel word for that) you see those around a lot during chinese new years which just passed. in some cases, the fruits will eventually fall off and the
plant dies, but in other cases, the
plant can survive year from year (some people just tos sthe
plant out after new years...such a waste to me but tradition goes on...) care for it like any other citrus
plant, occasiionally add some crushed egg shell (no egg though!) on top of the soil to let the
plant absorb some calcium and it should do fine
