Acer Rubrum 'HOSR'

Summer Red® Red Maple

The Summer Red® Red Maple, also known as Acer rubrum 'HOSR', is a delightful tree that offers year-round interest. This tree is known for its unique color changes throughout the seasons. In the spring, the leaves emerge with a red color, then transition to a dark green in the summer, and finally turn to a vibrant red in the fall.

This variety of Red Maple typically grows to a height of 35-40 feet with a spread of around 20-25 feet at maturity. It has a moderate growth rate and prefers full sun to partial shade. The Summer Red® Red Maple is adaptable to a variety of soil conditions but thrives best in slightly acidic, moist, well-drained soils.

Like most maples, it's important to water this tree regularly, especially during dry periods. Pruning is best done in late summer or early fall to prevent sap bleed.

MAINTENANCE NEEDS:  Low maintenance.  Water regularly.  Potential issues include stem canker, leaf spots, and root rots.  Potential insect pests include aphids, scale, borers, and leafhoppers.  Verticillium Wilt can be fatal.
