You can trim how ever you want, i have done them with no trimming to total success, but i prefer to cut the leaves in half and all but 4 shoot locations, once again, just my preference....







All of the stems should be about 1 1/2" to 2" down, No Further! trust me when i say no further, they will be growing roots everywhere, they will even be coming out the tops of the neoprean plugs! keep the parts you wanna root small, harder to repot otherwise.....
