Hi, Mel,
This is very typical with A. palmatum. Sounds like your tree has leaf scorch - caused by too much sun wither when the leaves were young or even now, or frost when the leaves were young. Another cause could be not enough water during a dry spell. As long as the pale tan stays at the leaf edges, there is nothing to worry about. Next year, when the leaves start to unfurl, make sure the plant is protected in the event of spring frost. Also, make sure throughout the year that you do not overfeed your A. palmatum - they don't like to be fed much at all. By the way, if you have an account with Shoot, you can add this to your 'Plants I Have' list and get detailed instructions on how to keep it healthy and happy.
All the best,
Kathy C
