English oak tree maintenance
English Oak is one of the most common park trees in south-eastern Australia, noted for its vigorous, luxuriant growth. In Australia, it grows very quickly to a tree of 20 m (66 ft) tall by up to 20 m (66 ft) broad, with a low-branching canopy. Its trunk and secondary branches are very thick and solid and covered with deep-fissured blackish-grey bark.
While the common or English oak (Quercus robur) is perhaps the best known of all the oaks, it is just one of around 600 species that make up this genus belonging to the beech (Fagaceae) family. The genus is mostly comprised of deciduous or evergreen trees, but there are also a few shrubs.
Most oaks have a domed canopy and a broadly branching habit. While many species have the characteristic lobed leaves, others have simpler, toothed foliage.
Hardiness varies, with the evergreens generally less hardy than the deciduous species. Most oaks are too large and ground robbing for small gardens but are magnificent specimen trees for large gardens, arboretums, and parks. They do best in full sun, but young oaks will tolerate a shady position.
