Description:
The Red Oak is one of the most rapidly growing and vigorous Oaks. It has an upright growth habit in youth that spreads dramatically and gracefully with age and bold texture in foliage and when bare. Branches are relatively few from the trunk as compared to other Oaks, but as a result each tends to be very large, with the lowermost branches being horizontal and quite wide-spreading at maturity. It forms large shade tree maturing at about 20 m tall by 25 m wide under urban conditions, but much larger in the wild. It has medium growth rate and upright oval growth habit in youth, becoming rounded to spreading with age. It grows best in full sun and is partial shade tolerant in youth. Performs best in full sun in moist, deep, acidic, well-drained soils, but is very adaptable to poor soils, dry soils, and soils of various pH. Its leaves are shiny dark green, alternate, with an overall obovate shape and their fall colour is usually brick red to scarlet and very attractive. The tree produces a relatively large oval acorn (2,5 cm long) that matures over two seasons. The fruit production is often abundant. Trunk is dark gray to black, lightly furrowed through middle age, and becoming deeply furrowed with a light reddish interior bark in old age. It can be used as shade tree for large lawns, parks, golf courses, corporate centers, or naturalized areas. It is a valuable timber tree and its abundant nuts attract wildlife (large birds, deer, and especially squirrels. Urban tolerant in general, especially to dry sites and one of the best Oaks for transplant success. (zones 5 to 8). Soil pH: 4.3 - 6.5
