Like growing a potato plant, as the yakon grows, can I continue adding dirt to the container? And I have a whole new plant sprouting off the trunk of my yakon. Is this normal? Thank you.

Soil temperature here is never 50 degrees FH, nor do we get Frost's My question is... How would l grow it in a Frost free tropical climate where the soil temperature rarely drops lower than 85 farenhite As we don't get frosts, will it die off or produce flowers and yacon all year, Can it even grow in a Frost free tropical climate. How can I treat it like an annual and a perrinial everywhere else I just bought one and ? Thanks to whoever can helpme
