Re: [Aroid-l] Cold Tolerant Amporhs

None of the konjacs are very deep. The largest maybe 6-8 cm, and smaller
ones are sometimes just below the surface, maybe 2-3 cm. I only disturb
them when I need to dig a few to give someone, so they have been mostly
left to themselves for more than 20 years in a couple of spots, and that
seems to be the level they like.
I don't know about the bulbifer - it's just the one, so I leave it alone.
