Hello, this is not a crepe myrtle but a Purpleleaf Sandcherry tree which as you know are a lot alike. I searched for every single video online and all of them show how to prune a fully grown mature mytle. None of them show or really explain how to prune a young one. So do I remove all of the stems and leaves on the bottom and leave only the ones on the top so that it has the long bare branches and a puffy top? Here are two pics of my purpleleaf I really don't know where to start. I am guessing I have to remove the stems that are growing straight up from the larger curved one?
