I have the greater yam growing in my garden. Had a lot of trouble to start with dogs digging out tubers. What do I need to do to promote aerial tubers? Also how big can this yam grow as vines are growing very long and high!!

I have bought some tubas. But unsure when to plant. Now living in Ridgley Tasmania. Can the tubas be left in garden or do they need to be lifted each year. Many years since I've grown them. Thanks. Gail
