i dont know what i was thinking but i threw away the topsThe tips can be replanted and they will be fine.
When you remove the tops, you remove the auxin producing part of the plant which will encourage lateral shoots to develop. In other words, the stem will produce new "tops" and you will get a bushier effect.
i see what your talking about. so its going to make a new stem from the node, they're starting to grow already.You will see new growth at the nodes.
