Orange trunk is oozing - what is it?

chara2(9)March 13, 2013

I have this Valencia Orange for 2,5 years. All this time it has been planted outside. It has survived 2 crazy florida winters with just some leaf drop and produced about a dozen of good tasting oranges. But about 3 weeks ago I noticed a small drop of ooze on the trunk, a little below the grafting line and now it has increased a lot and got me worried. The tree has dropped a lot of leaves, but what is left seems as normal foliage, just a little frost bitten . So what it is with the trunk? Please, advise.

Absolutely everything you've mentioned....location of the lesion, 'crazy winters ', leaf drop...makes me think of gummosis, a pretty common systemic disease affecting citrus (and other plants). It's caused by one of the ubiquitous phytophthora organisms.

Thanks, rhizo!
I probably will get rid of the tree in this case. So sad.
