All seedlings, young plants and mature plants of the smaller growing species are grown in: 1 part ground (milled) sphagnum moss 1 part perlite 1 part charcoal (1-2.5cm pieces + dust)

Mature plants of the larger species (e.g., Alocasia robusta, A. sarawakensis, etc.) are, when they are c. 20cm leaf diam., moved into: 1 part perlite 1 part charcoal (1-2.5cm pieces + dust) 1 part sterilized mineral soil

Climbing species such as members of Rhaphidophora, are established as young plants in a mix of: 1 part ground (milled) sphagnum moss 1 part perlite

and then planted out at the base of trees and allowed to begin vining. If they are to be kept permanently in pots then they need to be provided with a suitable climbing pole. We find that rough saw wooden pots, which must be raw wood and not treated with preservative, are the best support as they provide an excellent surface for the climbing roots. Plants that reach the top of the support can be gently trained to grow down the support and then up again, although you may find that plants trained in this manner, rather than allowed to continue an uninterrupted ascent, may be reluctant to produce mature leaves.
