What Is Causing the Leaves of My Japanese Maple to Be Brownish?
The stems and trunk are not affected and appear healthy. Most of the leaves are brownish. The leaves are red and very delicate. How should I treat this condition?

It may need water. Much of the country has experienced low rainfall and if this true of your area, then all you plants likely need at least an occasional good long drink.
It may also be a fungus, though you normally see spotted leaves and yellowing along with the browning if it is a fungus. If you suspect a fungus, treating the tree with a fungicide will help clear it up.
