Cultivation Details

Eucalyptus delegatensis is native to the temperate climate of southeastern Australia, where it is found at elevations up to 1,500 metres. Summers are warm and can be dry, with most rainfall occurring in the winter months and a dry season that can be up to 3 months long. Mean annual rainfall is within the range 2,500 - 3,700mm, sometimes as snow; mean maximum of the hottest month is 21°c; mean minimum of the coldest month is 0°c, and there are generally around 70 - 100 frosts a year[

Eucalyptus species have not adopted a deciduous habit and continue to grow until it is too cold for them to do so. This makes them more susceptible to damage from sudden cold snaps. If temperature fluctuations are more gradual, as in a woodland for example, the plants have the opportunity to stop growing and become dormant, thus making them more cold resistant. A deep mulch around the roots to prevent the soil from freezing also helps the trees to survive cold conditions[

It has beens introduced into South Africa in Zones E and G on a relatively small scale and showed good height and diameter growth, but did not become a preferred species. Several countries have good specimens but the main commercial plantations are in New Zealand. In New Zealand it is planted both in containers and as bare-rooted planting stock. With adequate root-pruning good seedlings are prepared and planted either by hand or by machine The trees grow vigorously but the leading shoot is attacked each autumn by the fungus Mycosphaerella nubilosa, which results in multiple leaders. One of these becomes the main stem early in the next growing season, but successive attacks of the fungus cause a series of large branches to develop on the trunk. This is not of great significance if the crop is being grown for pulpwood, but is more serious in the case of sawtimber[

Other Uses

An essential oil is obtained from the leaves. Total quantity of the oil, and its composition, can vary widely from plant to plant, but we have reports that the fresh leaves contain around 1.8 - 3.9% (2.5 - 5.6% dry weight) essential oil. The main components include phellandrene, cymene, pperitone, methyl cinnamate and eudesmol[

The heartwood is pale brown, straw-coloured or pinkish; the 30mm thick band of sapwood is almost white. The wood is open-textured, straight-grained, with conspicuous growth rings. It bends fairly well, is easily worked and polishes well.
