Answer: The tender, new leaves of Japanese maples can turn crispy brown when exposed to hot afternoon sunshine and/or drying winds. As your Bloodgood maple matures, the foliage will be less apt to get crispy brown margins, but while it is still young, the new leaves are quite tender. The damaged leaves will eventually be shed and your maple will continue to produce new foliage for a few more weeks. Make sure your tree is watered deeply once each week and be careful with fertilizers; too much nitrogen can cause leaf scorching, as well.
Best wishes with your maple!
