Scientific name: Quercus rubra
A fast-growing native Oak with a broadly rounded shape. The foliage starts out light red in the spring, turning dark green in the summer and finally vibrant reds and oranges in the fall.
Where it Grows: Red Oaks can be found from east of Lake Superior to Nova Scotia and is often planted as a landscape tree. This species grows mixed with other broadleaf trees and is intolerant of shade and competition. Plant in full sun for the best results.
Mature size and shape: Reaches 20 to 30 metres high. Thick trunk (up to 30 to 90 centimetres in diameter).
What you need to know to grow Red Oak: Tolerates a variety of moisture levels. Grows in a variety of soils. Hardy to zones 5-9.
Red Oak needs room to grow. It will not grow well if near other trees.
Oak wilt: Oak wilt is caused by an invasive fungus that has been found less than 500 metres from Canada. To help keep oak wilt out of Canada, save pruning for before April and after July, when the beetles thought to transport the fungus are less active.
Benefits and uses of Red Oak
