Arisaema tortuosum Care
Growing naturally in the foothills at height of over 1000m this is a cool to warm growing species, a part shaded woodland position is best and again this arisaema may also be grown in a container or large garden pot.
In the garden a deep humus rich soil is best, however good drainage is also essential to prevent the tubers from rotting. Many growers divide Arisaema tortuosum in late winter to spring, just as the growing season commences, this seems to help avoid problems of newly planted bulbs rotting, which can occur if divided in fall.
