In September 2021 I bought three mini ficuses (it said Natasha variant). 6-7 cm high pot and tall plant, excluding pot, about 25 cm. I put them in slightly bigger jars and two of those 3 died. One survived, which also fared badly, but then revived, which however remains dwarf and with very small new leaves. Is it generically dwarf or because its roots are tied up and I should untie them and put it in a bigger pot?
