Hello! I was traded this tuber over the winter and was told it was likely either konjac or bulbifer... Anyway, it doesn't seem to have grown much this summer so I'm wondering if this amount of growth is normal? Also, does it look good? It kinda looks yellowish to me. Just trying to make sure it has a good summer growth before winter comes around so I have a good chance of getting to grow it for more years.
Thanks for the help!
