Why Japanese Maple Leaves Stay Brown and Attached

It can be puzzling when Japanese maples hold onto brown, dead leaves well into winter. This phenomenon, known as marcescence, occurs in several tree species, including some crapemyrtles and young American beeches. The exact cause isn't fully understood, but it's generally not a sign of poor health.

If you prefer a cleaner silhouette, you can use a leaf blower to remove the persistent leaves. Otherwise, rest assured the tree will shed them naturally before new growth emerges in spring.
