Eucalyptus andrewsii

Cultivation Details

Eucalyptus andrewsii is native to the warm temperate and subtropical climate of Australia, where it is found at elevations from 600 - 1,200 metres. Summers are hot and moist, usually with some rainfall also occurring in the winter months. Mean annual rainfall is within the range 625 - 1,000mm; mean maximum of the hottest month is 27 - 32°c; mean minimum of the coldest month is 0°c, and there are generally several frosts a year^[1]. Eucalyptus species generally require a sunny position, succeeding in a wide range of well-drained, circumneutral soils of low to moderate fertility^[2]. This species is found in soils that vary from moderately deep loamy sands of good fertility to skeletals^[1]. The plant develops a lignotuber - this is a woody tuber that starts to develop near the base of seedlings and can become massive in the mature plants of some species. It possesses embedded vegetative buds, allowing the plant to regenerate following crown destruction, for example by fire^[3]. This species should adapt readily to plantation practice and would not hybridize with Eucalyptus grandis and other members of the subgenus Symphyomyrtus; it is a promising prospect and has proven to be moderately successful in Brazil^[1]. 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^[2]. Many members of this genus are remarkably adaptable however, and there can be a dramatic increase in the hardiness of subsequent generations from the seed of survivors growing in temperate zones^[2].
