These half-barked ladies often grow in the regions of Oz where there are only grass fires or lower storey fires rather than a full-on raging inferno, so they have no need to put effort into growing a full metal jacket.

This rather unnerving example is a Eucalyptus glaucescens 'Guthega', and looks rather like it has been in the bath for too long! So the pressing question is WHY do Eucs shed their bark in such a flamboyant manner? The jury is out to lunch on this one. Several theories are put out there, such as:. Shedding bark is a means of divesting the host of moss, lichen, fungi and parasites.

The Tasmanian blue gum E. The above may well be true, but our own view at Hardy Eucalyptus is as follows:. Eucalyptus are very fast-growing hardwood trees. They are highly adapted to rapidly convert soil minerals and carbon into wood fibre. This is what makes them excellent at removing atmospheric CO2; they are the carbon-busters.

The last thing this tree needs is to be constrained by tight-fitting bark. To speedily expand your waistline, you need quick-release clothing…I believe! A sappy young tree carries semi-protective but spongy periderm which allows for rapid growth in the early years, but it leaves them vulnerable to be chewed off before they reach their prime.

Whereas older Eucalyptus have invested a great deal in their woody collateral and need solid protection, in the form of rigid bark, from munching predators. Eucs lay down carbon-rich heart-wood every autumn and timing is crucial. What they require is a quick and easy way to expand their girth in preparation for the autumn augmentation without having their barky defences compromised for too long. Newt , Sep 16, Thanks Newt It looks like my tree is Eucalyptus niphophila, although it's a little hard to tell from the only pic on the website you pointed me to.

Will see if I can find other pictures on the web. Will also take a pic of my tree and post it later. BrianT , Sep 17, Greetings Brian, You may find that most euc species in britain are of the smooth bark varieties. The trees at 9 years old are becoming mature. With maturity comes annual or biennial bark fall as the tree branches increase girth size fairly quickly. You should find in the lower trunk area, that the beautiful mottled bark has been replaced with a harder corky type of bark also.

Eucalypts grow to become very large trees and have a tendancy to drop large branches without notice. Never ever cut roots thicker than 50mm as this will invoke a decent branch to drop with very little notice,.
