Vegetative propagation of Arisaema ringens

[Martin Ashworth]

Hi Nancy
Offshoots which appear as swellings or discreet but attached small tubers
have been pulled off from main tuber normally when tubers have been lifted
to move to a different site or into pots for winter storage if particular
species are subject to rotting of tuber in wet winters of likely to be
affect by frost. This is usually done when all above ground vegetation has
gone and tubers are becoming dormant.
Some species are helpful, Tryphyllum last year, November,  produced
offshoots which detached themselves. I lifted one to move to another
location and when I located tuber, 3 offshoots lay next to and detached from
main tuber. These were put into small pots in barely moist potting compost
for the winter, frost free greenhouse, they were not watered until shoots
started to appear early April, (on all of them).
