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[

Edible Uses

None known

Medicinal

Kino resin, obtained in small quantities from the trunk, is very astringent. Diluted, it can be taken internally as an effective treatment for dysentery, working because it is not absorbed at all from the stomach and only very slowly from the intestine, and is thus able to directly treat the lower part of the intestine. It can be used as a gargle and mouthwash to treat relaxed throat, loose teeth[

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 0.5 - 1.0% essential oil. The main components include alpha-pinene (around 33%), eudesmol (around 35%) and globulol[

A small quantity of kino resin is obtained from the trunk. Kino resins are rich in tannins and are very astringent. Soluble in water, they can be used medicinally; in tanning; as well as for preserving and dyeing natural fibres. When boiled in an iron pot they produce a thick, dark liquid that can be used as an ink[

The resin oozes naturally from wounds in the trunk and can be tapped by making incisions in the bark. At first it is a thick liquid, but soon hardens upon exposure to the air and sun, typically drying to an amber-like material that consists of dark red angular fragments, rarely larger than a pea. Freshly exuded kino is more effective than kino that has been on the tree for a long while, since the soluble portion can be more or less washed out and the action of the sun can alter their chemical composition[

Plant out into their permanent positions in early summer and give them some protection from the cold in their first winter. The seed can also be sown in early summer, the young trees being planted in their final positions in late spring of the following year. The seed has a long viability[
