so I am guessing this means you need to trim carefully above the nodes....not just taking scissors to it?
What I meant was not specifically trimming each one specifically at the second internode, but just to trim it fairly low to prompt it to throw side shoots. The second would be a safe bet so you dont kill it. A plant that branches like this has a tendancy to sprout a side shoot from the first healthy internode just below the trim. If you get too close to the second, then it still has a chance to sprout from the 1st. If you trim all the way to the first, them you run a higher risk of it just plain melting. And once your second internode shoots creep and root on their own you can trim a little bit lower if you're really picky about how low and uniform you wish for it to look.
