Did you try switching the voltmeter from DC to AC?  Also, try another time of day or night?  Living things may be using more subtle forces than we can measure with our instruments?

Just some thoughts,

Hey, you know how you can jam your VOM leads into a potato or a lemon and get about 1/2 volt? I wonder if you could jam your leads into a tree and get any reading?

Expose a root and push your + lead in, extend your - lead and get it as far away as you're able, push it into a branch and see what happens (I can't do it where I live, I'm in the middle of the desert, no trees...). If you don't get deflection, switch polarity + for - and check it out again. I like analog meters for this kind of thing (like a Simpson 260), digital sampling in VOMs can get a little sketchy for some stuff.

Use the smallest DC scale you have. Make sure your leads have good contact. See what happens.

"...pH difference between xylem and soil..."

Using tree power to prevent forest fires?

"...Here is the abstract. “It has long been known that there is a sustained electrical potential (voltage) difference between the xylem of many plants and their surrounding soil, but the mechanism behind this voltage has remained controversial. After eliminating any extraneous capacitive or inductive couplings and ground-mediated electric current flows, we have measured sustained differences of 50â€"200 mV between the xylem region of a Faraday-caged, intact, potted Ficus benjamina tree and its soil, as well as between its cut branches and soils and ionic solutions standardized to various pH values. Using identical platinum electrodes, no correlation between the voltage and time of day, illumination, sap flow, electrode elevation, or ionic composition of soil was found, suggesting no direct connection to simple dissimilar-metal redox reactions or transpirational activity. Instead, a clear relationship between the voltage polarity and magnitude and the pH difference between xylem and soil was observed. We attribute these sustained voltages to a biological concentration cell likely set up by the homeostatic mechanisms of the tree. Potential applications of this finding are briefly explored.”..."

@RR,

It may be worth while to try wrapping a cloth insulated wire around the root and another around a branch of the same tree.

I know Nathan Stubblefield used wire of that type, and its said he used trees to power lanterns...with wire wrapped around the roots.

Not sure if this is the same, but see this:
