I recently purchased this bare root dwarf romeo cherry tree. When it arrived it have quite a lot of leaf buds popping so I planted it, added the tree fertalizer, kept it watered but we had a really bad heat wave with 5 days of 90-95 F days in a row and the whole week was 86+. Every single leaf but died back and I thought I lost it as it sat sad and black for at least 2 weeks. I ordered a replacement and all of a sudden... life! This is it now. My concern is that all the new leaves are really low. How do I now shape it into the nice ornamental trees that they are meant to be?

This will be my first attempt at this sort of tree but its pretty much my dream tree! I dont want to mess it up and it would be amazing to end up with two nice ones.
