Nature spirits (elementals) like faeries, elves, gnomes etc are well known for their tending to plants and nature in general. Believe it or not, they do exist, and I have good reason to suggest that if humans were aware of this in general, and made the effort towards respectfully communicating with them (such as asking for their help in protecting the plants) they could and would do much more to help us with our relationship with the natural world as they mutually benefit from it too. I have my own numerous experiences to attest to relating to them and I know they are at least part of the equation, perhaps actings as the liasons between human consciousness and the plant kingdom. The response of the plant kingdom to our thoughts and our interaction with it is facilitated through them if not their doing, whether we are aware of it or not.

The plants may also have a voice and consciousness independent of the nature spirits for all I know, but I don’t think it would be apprehended as a voice or voices but instead as a vibration or frequency. The music or whatever that is played for a plant might be actually enjoyed by the nature spirit (which are intelligent to varrying degrees) and thus entertain it more or less, keep it around, or drive it off, thus aiding the plant or not. Reason I think this may be the case is because the studies aren’t consistent, sometimes classical music makes the plants grow better, sometimes rock n roll does for example. Those inconsistencies tell me it might therefore relate to the preference of the nature spirit, which has it’s own variable tastes like a human would and which fits the folklore.

WIth or without the nature spirits, the sound vibration may also be harmonious or not to the plant, and so may still play a role independent of the spirits. Conjecture on my part but food for thought.
