Cultural Notes: Oaks are very large, long-lived, ornamental trees that are suitable for parks, large properties, and arboretums. They should be planted in full sun, but young oaks will also tolerate part shade. Oaks prefer deep, moist, humus-rich soil. They are generally low maintenance but may require some pruning when young, in order to establish a single trunk. Propagation is usually from seed. They produce male and female flowers (wind pollinated catkins) on the same tree each spring. These are usually green or yellow and are followed by the fruits, known as acorns. Quercus lobata is extremely drought hardy as long as it has access to groundwater, which it sends massively deep roots down to seek out. It is a very slow growing but spectacular feature tree. In south-east Australian conditions you could expect a 12m high x 12m wide tree in 50 years and only a short deciduous period. It actually comes back into leaf in early August, a month or so before most of our deciduous trees.
