I've pulled ligtu seedlings at the 2 or 3 leaf stage and I've also 
let them go until they were dormant and had formed a small rhizome. 
The latter transplanted well, about the same as the large clumps I 
always dig when I'm dividing well-established ligtu.

Some seedlings when they're divided in the green growing stage are 
easily broken right below the first leaves...when that has happened 
I've usually lost the seedling so that was another inducement to wait 
until the seedlings had gone dormant (I have some now in a tray that 
are a few weeks away from becoming dormant).
