I only sell root trained plugs. They establish more quickly and generally don’t require staking 😉

Eucalyptus Globulus plug comparison

General characteristics:

Hardy:Medium to -8°C
Soil:Will grow well in a wide variety of soil ph, moisture laden clays or good free draining soil.
Growth:Very fast, up to 2m per year
Height:Generally around 30m, can reach 60 plus in ideal conditions.
Biomass:There are many plantations in Southern Europe, mainly for paper pulp, though also short rotation coppice and constructional timber.

Common names

Also known as; Tasmanian blue gum

From the get go, this tree has impressive growth rates Viminalis is fast, but the stems can be a bit spindly to start with. Not so Eucalyputs Globulus !

Globulus does confirm my theory about Eucalyptus using up all the nutrients in the soil and nothing grows beneath them myth. They do shed a lot of fibrous bark, and if planted close together this shedding can carpet the forest floor and make it difficult for other plants to grow.

NOTE I’m not saying this is a bad thing, indeed the opposite would be the case if you want a forest akin to a well established beech forest which exhibits the same lack of plant growth, but due to the amount of leaves large beech trees shed every autumn.

Eucalyptus brash makes fabulous fire starters, collect all the shed bark and you’ll save on fire starter logs or paraffin block 😉

Eucalyptus Globulus bark shedding

There’s a good report on European Tasmanian Blue Gum, the common name for Globulus.

When I first started this business it was to provide Ireland with an alternative to burning peat. Most Eucalyptus trees provide high grade firewood, however, the more I research and read up about Eucalyptus, the more I appreciate just what a valuable resource these mighty trees provide. In the case of Eucalyptus Globulus the uses are wide ranging, and some are very applicable to Ireland and its agricultural economy.

I recently had a chat with a neighbouring farmer about fence posts. I want them to simply plant a stockade of Eucalyptus so that they can do away with the electric fence and environmentally damaging creosoted fence posts which are banned for domestic gardens, and as of 2023 are being phased out for agricultural use as well ! Said creosoted fence posts are guaranteed for fifteen years. The normally treated ones for five, though from talking to other farmers, they generally need replacing within five and two years respectively. If they planted Eucalyptus they would be able to harvest a valuable biomass crop every five years minimum. Though you could grow Eucalyptus Globulus for poles and posts, and even without treatment they are good for fifteen years in wet ground 😮 source Forest Culture and Eucalyptus trees

Eucalyptus Globulus grow faster than spruce, and you don’t need to treat them, so they must surely be more profitable to the forester.

Other uses:

  • Constructional timber
  • Low grade veneer
  • Plywood
  • Flooring
  • Furniture
  • Tools, presumable shovel and pick axe handles etc.
  • Boxes, crates, pallets
  • Railway sleepers
  • Mine props

When wooden sailing ships were the norm Blue Gum was extensively used in marine construction due to the large straight beams that could be cut from the huge trees. So often as keels, but also for planking. It is very durable in sea water and water generally. Hence my curiosity about it being a tree suitable for the Irish fence post industry. Currently my understanding is that most of the creosoted fence posts are imported from the Netherlands.
Globulus are however very good biomass and firewood logs similar to Nitens, though Eucalyptus Globulus can be coppiced giving a sustainable three rotation crop before replanting is necessary. For those of you interested in Eucalyptus for constructional timber, then the video below is of a Eucalyptus Globulus being slabbed using an Australian portable timber mill specially designed for processing Eucalyptus hardwoods. I’m still surprised at all the negative stories I heard when I first started growing and promoting Eucalyptus as a suitable timber species for Ireland. Initially I was just growing and promoting for firewood, though now, more and more as a diverse species with many uses, including high quality constructional timber.
