Very difficult to know. There has been anecdotal evidence (??) of 
electrical treatment of plants with various effects. It is possible that 
electric fields of some kind exist and are affected by plant health and 
that those can be sensed by other plants. There's that business of thorn 
trees in Africa responding to giraffes browsing on their foliage and 
becoming bitter tasting. Not just the tree being eaten, but all the 
trees in the copse. Sending the giraffes elsewhere.
Do plants use electrical fields to detect areas of high nutrient 
concentrations, thus giving them a direction to send their roots in.

 :) then there's the sci-fi story about plant communication "on the 
grape vine" but that's highly ET :))
