|I know it sounds confusing, but the tips of the stems of your plant is where new growth will emerge. If you pinch back only about a quarter inch of the very tip of the stem you will redirect the plant's energy to the nearest node (leaf scar) on the stem. Two new stems will emerge from near the nodes on the stems. Allow these to grow 3-4 inches long and then pinch out the very tips of these stems. Two more stems will grow, etc., etc. You'll end up with a bushy plant. Once it is full and bushy you can allow the stems to grow 8-10" long before pinching out the tips again. If you're still not sure how to go about this, do a test on just one of the stems. Pinch it back by a quarter of an inch and watch to see what happens. Once you figure out how to guess where new growth will emerge on a stem you'll be able to pinch and prune with confidence. Hope this information helps!
