Hi Robert, I think you did a great job, hope it grows well. I have a very similar one in my back yard and am constantly saying I'm going to do what you did, then, like you, I get to feeling bad about possibly killing it. You've given me hope, I'm going to try and get to it very soon, but in my case I think I'll also cut the branches low and getting it to look more symmetrical, How many drain holes does your pot have?
