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'd go with the online info. We plant October/November, harvesting May/June (better after the first frost). They can take their time to really take off - ours had minimal foliage until March.
