Yams/oka need about 5 months to grow before harvesting. They can be planted when the soil reaches about 17 degrees C (a bit over 60 degrees). if you can fit these requirements you should be right. Harvest them after the leaves have started to die down to give them the most opportunity to make size.

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!!
