i had the same problem.. ok, u take about 3/4 of the tree, and put it into another tree, that is putting them together sidebyside, i cant figure out how to do it up and down yet, heh

/edit

ok, i was just thinking, and this works pretty well....
make an npc and set it to treetop.gif
then connect however many treetops that u want, and just use the tiles to add the bottoms. it works really well
