I watch and predict failures a lot these days, over extended leaders with a cabbage patch on the end.

It's all about light, shading out by canopy above so grow further and frankly, no really bad storm, ice and snow the bust them and teach the little grubs a lesson.

So, this in turn is what spurs the topping of eucs. People seeing failures so they beat the failure by topping it and also get a denser crown. This is why many times we thin them over reducing them, but you have to thin them out on the ends and many times a bucket truck is required or a very agile light weight climber, and I'm talking secatures and limb lopper pruning not chainsaw.

Now if you go up to the snow areas and see the snow gums they aint as bad, coz nature sorted them out and they learned, genetics or evolution etc.
