Wilbert is absolutely correct. We find that none of the indigenous
Bornean Amorphs are dormant for long. In fact, many species are
effectively in leaf all the time in that a new leaf is emerging as
the old leaf is in its final stages of senescence. We grow in
coconut peat, coconut fibre, washed coarse sand and a small
proportion of burnt soil, water copiously and also feed copiously.
The minimum at the nursery here is 22 C (c. 72 F) and the maximum 34
C (c. 93 F).
Peter, can you speak to the "burnt soil" component of your potting
medium? What does it add to the party? How is it prepared? Just
guessing here, but is charcoal anywhere close to a reasonable substitute?
