What about it?

Red maples are typically a bit larger than their Norway maple relative. But they do have the same opposite branching characteristic of all maples and the helicopter method of seed dispersal. The leaves are smaller with 3 prominent lobes and irregular teeth. In the spring the female tree produces beautiful blooms of small red flowers and in the early fall the red maples are the most spectacular tree on the block. These trees didn't get named "red' maples for nothing!

What is it used for?

Red maples are used primarily for decoration although they do provide a good deal of shade.

Where does it grow? How do we grow it?

Red maples can become quite particular about their growing sites. They require a moist, fertile, slightly acidic soil. If they are planted in a dry area, or an area with poor soils, their growth will be considerably stunted. They also need about 50 feet of growing space.

What are its primary problems?

Red maples have moderately weak wood and may suffer from Verticillium wilt or Anthracnose.
