Quercus rubra or Red Oak
Originally from North America, Quercus rubra or Red Oak is a tall deciduous tree with brilliant autumn foliage. Reaching a height of 40m + depending on conditions, although in cultivation often around 20m.
With a moderate growth rate final height will depend on location, in an open situation the tree will develop a shorter trunk and broader crown than in closely planted forests.
In ideal conditions this tree can grow at a rate of 2m a year when young, slowing down as it gets older.
Foliage is characteristically glossy alternate and dark green. Flowers in the form of catkins are fairly insignificant. Bark is grey and smooth. Early growth is pyramidical however as the tree reaches maturity the rounded canopy is more common. Q. rubra ‘Aurea’ is the golden oak.
Landscaping Uses
As a shade tree in a larger garden or park this is an excellent choice, the brilliant red foliage in autumn is an added attraction. Typical acorn fruit after flowering.
Care
Although a hardy species Quercus rubra or Red Oak does prefer a humus rich moist soil. It will grow more rapidly in good conditions. Full sun although this is a tree that also copes with part shade. Little to no pruning other than removal of dead wood.
For more rapid growth ensure that water is available during spring and summer, particularly during dry years. Water deeply during summer.
