Um, slightly embarrassed but found another one down behind the fridge - an escapee from the veg tray on top.
It's trying really hard to reproduce, and has grown nodules over its surface - about 8 of them, each with roots and some now growing leaves. It looks as though it would make a few individual plants. The original tuber is looking a bit wrinkly.
Do I:
a) chuck it? (seems a waste)
b) plant it as a one-er? (think I'll get a few plants close together)
c) divide it into 8?
If I divide it, do I pull each one off the main, or do I cut the main one to feed each individual nodule? In either case, do I need to dry the surface before I plant?
Thank you for any advice.
