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!!

Did you plant at the right time. Probably don't over water or fertilise them.
