Crown die back in Eucalptus

[Happy when high]

Today I removed a Eucalptus that had declined very suddenly. It had been lightly reduced in October last year. Pruning cuts looked good, all in all not a bad job. Since the reduction mostly in the last few months the bark has split in the majority of unions and exposed rather a lot of dead wood underneath, 90% of the foliage had died and the tree definitely had the swagger of a dead tree. I think it may have been fungal because there were dark markings inside the majority of the canopy's wood but not a lot in the wood lower down the tree. Is this something that has got into the tree because it was pruned too late or is it something else? Unfortunatley I dont have any photos. Any answers would be most appreciated.

 

Many thanks.

Sounds like possible frost damage....

no doubt frost damge, in fact if you look at the cuts across the logs youll see the most damged cambium is where the bark had peeled last as was at the time of frost very thin.

 

did one yesterday and it was clear where the smooth areas of bark where the frost had penetrated into the cambium bruising it. under the thicker plates it was o.k

So thats quite conclusive then, frost damage caused by late pruning. Thanks for all the help.

No it's frost damage caused by ....... Frost.

 

Euc's don't like cold weather and the frost kills them. Not surprised with the last couple of winters.

I've done a few since hard winters, 95% sure it was frost damage as no evidence of anything else in any of them. Nada!
