Ficus tree bonsai - beginning
 

I'd appreciate any website info or primer on this particular tree.
Specifically, to start ... I found a special at my local Home Depot.
10" pots with trees 36 - 48" tall and 1/2" to about an inch in
diameter ... each pot has 4 - 6 trees. What's the best way to begin
.... should i separate these trees, or bind them so they form one big
fat trunk ? Some have no branches for a foot or more ... and i don't
want my finished tree to be that tall ... if i trunk chop, will it
grow branches ?
