Oak Leaves and Citrus Greening

An interesting and topical science report.

Living, as I do, where the greening disease has been found less than 20 miles from my home (as the crow flies), it's just a matter of time before it makes its way to my neighborhood.  Almost every home has a lemon tree, an orange tree, or some other citrus.  I have 7 citrus trees.  We enjoy them year round, using lemons and limes in our cooking, and eating the various mandarines and oranges throughout the cool months.

I hope there is something to this.  I'll plant an oak tree in my front yard just for the leaves!  

But a secondary problem is that sudden oak death disease is also found in our area, so that complicates the scenario.  Anyhow, thank you so much for posting this article.

Marco,
Maybe you are already doing all the right things to protect your trees. Compost tea sprays, Mulching and having biologically active soil with lots of fungi. Cover crops too.  You are probably as ready as anyone for the battle against citrus greening.

There are lots of wild citrus trees thriving in live oak hammocks, under the canopy here in florida, where entire orchards have died in the same area from the greening. There might be some mychorrizal benefit of growing near oaks as well.

To all here that are in areas of concern about greening disease. The component of the oaks that seems to be the beneficial is the tannin (tannic acid), that would be why the leaves do well at preventing this disease.
If you can get the mycorrhizae for oaks and install it to your citrus tree's root systems, there should be some good benefits to those citrus trees, add to that some sea minerals (use a good non-purified sea salt) sprinkled all around each tree from aprox. 6" away from trunk to outside the drip line.
This application will provide more minerals for the microbiome so it stays very healthy which will also help in disease prevention.
Good, aerated compost teas are always a good thing to use on trees subject to catching any disease or infestation.

Good luck, may wakantanka watch over your orchards, no matter how small.
