Norway Maple

About Norway Maple

Norway maple (Acer platanoides) is a deciduous tree that typically grows 40 to 60 feet tall. It was imported from Europe and western Asia and was used for landscaping in urban and suburban areas. Unlike the sugar maple, it has milky sap. Varieties with red and purple leaves are common.

The Problem

It produces large numbers of seeds, and develops dense stands that out compete native plants.

The Solution 

Mowing or hand pulling of seedlings and small saplings can be effective. Mature trees will re-sprout from the stump if not treated with a systemic herbicide. Girdling (removing tissue around the circumference) of mature trees may be effective, especially when girdles are treated with herbicide. Always read and follow the directions on the label when using herbicide.
