Sounds like a myth, but a similar caution exists for peonies and irises,.
It's based on the first plant taking up the available nutrients, and/or the
existence of pathogens in the soil. Why not do an experiment and try it
under controlled conditions.? Dig up the area, changing the soil levels,
add some appropriate fertilizer and./or leaf mold. I can imagine it's being
true because of the (to me) relatively small root systems I see on arisaema
tubers. But, a major factor would be the mycorrhizae that were symbiotic
with the plants, effectively extending their nutrient areas.
Good question, Petra, and I hope there's some discussion on this. Adam in
