I put it down. It has actually produced seeds consistently for several years. The seeds
are smaller than my other trees, but they have good germination rate.
I have layered all 6 trunks. But only 3 medium ones produced roots. I could not wait any
more, so last week, I chopped them off. Also cut down the 2 two that have roots.
I dug it up on the 03/Jul/2010 -- these are the pictures.
The picture below is it after I axed off the big roots at the base:

The following two show the positions of the trunks:


And finally ready to pot:

It has root in all direction. The length of the root based is about 30 to 35 cm.
The biggest trunk is about 6 cm. The smallest is about 3 cm. The length of the fused
base is around 15 cm.
I put it into a wooden box. It would take three-of-me to carry this box around now.
