Tree & Plant Care

Avoid pruning in early spring as maples are 'bleeders' and will lose large amounts of sap.

Disease, pests and problems

Verticillium wilt (fungus) is a potential problem for maples.

Native geographic location and habitat

Native to Northeastern Asia.

Bark color and texture 

The light brown bark exfoliates in vertical strips to show golden-brown inner bark.  This provides an interesting winter feature.
