I was recently involved in a discussion about how Burls form on Eucalyptus trees. Well, I Googled “Eucalyptus Tree Burls” before extending my opinion any further, and just as well because I learned something new this morning. It appears that Burls usually form from a Disease of some sort, or from stress to the tree. this can be from insect attack or from physical stress such as wind, water or fire.
So thanks to the person who enlightened me and has also been enlightened.
Attached are a couple of images of a “Salmon Gum” and also a River Red Gum. The River Red Gum is almost entirely Burl for at least 6 feet of it’s trunk. Man, would I love to have that in my shed.
Hope you find this interesting and I apologise that I cannot provide the link to this particular site, I’m technologically challenged.
