We start here a thread depicting Eucalyptus cultivation around the world. Some 200 years after their discovery eucalypts have become some of the most important travelling plants in human history, introduced in countries in all continents. Their importance as source of timber and non timber products, as landscape elements, as ornamental plants, is one of the outstanding contributions of Australia to the world.AustraliaSaudi ArabiaChinaAcknowledgementsWe will be adding here a list of contributing authors.

Growing Eucalyptus from seed: it is in the detailsGustavo Iglesias Trabado GIT Forestry Consulting - Consultoría y Servicios de Ingeniería Agroforestal - www.git-forestry.com - EUCALYPTOLOGICS(click image to enlarge)Propagating Eucalyptus from seed is easy. But easy and efficient are variable concepts that have to be considered depending on plant production targets. Amenity growing and commercial nursery production share the same basic concepts, but a considerable amount of extra details must be considered in each particular case.The basic idea should always be "each seed matters" no matter at what stage of seedling growing you are. The closer the final results are to this key initial idea, the better. But inbetween the ideal maximum efficiency and total failure many results can be satisfactory from both technical and financial points of view.Today we present you a small sequence of basic stages from Eucalyptus seed sowing to final plant dispatch using one of the simplest methods

Eucalyptus trials in Oregon Country: Stan & LeeSome early work with Australian trees in the Pacific Northwest Gustavo Iglesias Trabado GIT Forestry Consulting - Consultoría y Servicios de Ingeniería Agroforestal - www.git-forestry.comEUCALYPTOLOGICSThe cultivation of Eucalyptus in the Pacific Northwest has had to do with trialling of species for relatively a long time now, sometimes as ornamentals and other times as part of forestry hardwood trials. It is however a relatively recent trend, especially if compared to the very old tradition for the cultivation of Eucalyptus in California.One of the steps in this process of increasing eucalypt growing had to do with the works of an Oregonian forester, keen tree grower and adventurous fan of the Australian trees.Lee O. Hunt (1912?-2002), who would later be President of the Douglas County Small Woodland Association, started methodic experimentation at nursery and field trials with 14 species of Eucalyptus back in 1971, focusing in

Phenology of E. macarthurii in Galicia (Northwestern Spain)Blooming starts: AugustBlooming ends: OctoberNº simultaneous flower/fruit crops: up to 3Seed maturity after flower bud formation: 18 to 30 monthsSeed maturity after blooming: 12 to 18 monthsThe Eucalyptus of Sir William Macarthur can reach up to 40 meters height when grown at forestry plantings on good sites, or remain a shorter tree of wider crown and retaining basal branches when grown as isolated specimen (20-30 m).Its quite good cold hardiness, resisting down to -10ºC and more than 80 frost events per year, and its average growth rates, made of it one of the alternative species in Northwestern Spain to E. globulus for inland areas or beyond 500 meters above sea level before the widespread planting of E. nitens.Prolific in flowering, individual blooms are very small sized and difficult to notice. In clusters of seven, they become small white masses, same way as E. pauciflora. But these inflorescences are yet the size of a

One of the factors that have been used and abused for the demonisation of Eucalyptus trees is "their ability to deplete soils, so nothing can grow where eucalypts once grew". A myth very in the same line of the "nothing grows under gum trees" one. Pretty surely those propagating these ideas and those giving credit to the previous have never been to the natural habitat of these trees in Australia, whose rich agricultural and livestock production happens each day mainly on previously cleared land once covered with eucalypt forests. And quite possibly myth believers have never been into an eucalypt plantation either.What is sure is that Eucalyptus can perfectly be grown under sustainable forestry principles, and that knowing your soils and your plants before taking opinion is very important. Soil management under sustainability philosophies relies basically on the simple principle of "what you get out of it should come back". Return nutrients that you extract, or at least try to minimise

Here you have other three examples of cold hardy ornamental Eucalyptus. These gum trees are not, as we saw in a previous entry, destined to become specimen plants in big containers. These are for direct planting into convenient garden designs in USDA Zone 8. Some of these species would tolerate appropriate microclimates of USDA Zone 7 gardens too.

We have seen that certain Eucalyptus species can easily reach giant sizes in relatively short periods of time. With such a biodiversity within this plant genus (hundreds of species, subspecies, varieties and cultivars) giantism is luckily not always present for all types of gum trees. But a good deal of eucalypt knowledge worldwide has to do with their applications for timber production, and in such cases fast growth, good form and suitability to resist frost events by winter are some of the initial important considerations. However, for the urban gardener, especially if with limited space, alternative options need of some consideration.Here you have four examples of tamed cold hardy ornamental Eucalyptus achieving their final destination as plants in big containers, whose frost tolerance makes them suitable for cultivation outdoors in USDA Zone 8 gardens and favourable microclimates of USDA Zone 7 gardens.

By 1866 in the neighbourhood of Coimbra (Portugal) the first cultivated forests of Eucalyptus in Iberia were established with the planting of thirty five thousand trees besides the Mondego river and at Mata de Choupal. It was an attempt to tame the stream and control devastating soil erosion caused by floods. Until then, the Australian trees were botanical rarities and relatively uncommon even as ornamental plants in public and private gardens. It was also a long time before they became a paramount timber crop for Northwestern Iberia, but this protective afforestation can be considered the beginning of such an era.In the neighbourhood of Coimbra stands today an eucalypt tree that witnessed those times and that has grown straight and tall from the bottom of a foggy deep gorge in search of light to become the tallest Eucalyptus in Europe. It is the Karri Knight, an Eucalyptus diversicolor from Western Australia.Fig 1: The giant Grandfather of Chavín (Spain) and Karri Knight of Vale de C

We have previously seen images of natural regeneration in E. delegatensis, E. obliqua, E. globulus, E. nitens, E. blakelyi, E. nicholii and E. gunnii in which regrowth was present from lignotuber or axillary buds after the removal af the aerial part of the trees. Today we will see one of the natural equivalents to coppice growth after timber harvest, which is vegetative regeneration after fire.Snow Gums regrowing after fire in the Victorian Alps (Australia)(Photo courtesy of Phil in Sydney's Blog "Eucalypts In Habitat")This response in different eucalypt species is the result of adaptation to changes in their natural Australian habitat during millenia, and particularly to different degrees of natural selection pressure caused by relatively frequent forestry fire events. After the loss of their aerial part by fire, only the most vigorous coppicer specimens become dominant trees and, if free from further fire damage in the short term, are able to produce flowers, cross pollinate and pro

One of the controversial issues with Eucalyptus trees has to do with their root systems. Frequently exaggerated as a factor against their planting in gardens or urbanised areas as ornamental trees, menaces of doom to basements, pavements, drainages and other structures are widespread and even fantasy tales about their thirsty roots coming out of your kitchen tap are not that uncommon.Difficult to debunk this myth with some real facts without digging up a bit. And that is exactly what Dr. Hailu Zerfu in collaboration with the Institute of Forest Ecology of the University of Vienna did in the highlands of Ethiopia, which, as you may have guessed, it is also Eucalyptus country.Example of methodology to survey root spatial distribution and biomass and nutrient allocation in Eucalyptus fuelwood plantations established on deep heavy clay soils in Amhara (Ethiopia).
