The only sure way to get lower stem growth is by cutting any stem all the way back to the point where you would like to see that new growth. That is because almost invariably, new growth comes in only at the tip ends of each stem, not lower down.
Another option is to constantly pinch out new growth as soon as it first emerges at the end of any stem. That will keep that stem from growing longer and very occasionally may cause new growth to emerge lower down on that stem.
