How to get rid of lichen on grapevines
How to get rid of lichen on grapevines organically on vine only...not leaves? What can we spray that is an organically safe product on the vines? We have heard of baking soda or copper sulfate so far. Do you good folks have any good safe advice for freeing the vines of this lichen? We us no fertilizers on ground. This season we are trying (thedirtdoctor.com) method of corn meal and dry molasses on the ground to get the ground back to organic. We plan to spray Garret juice on vines and ground when we safely remove the Lichen. Thank you for your sage advise and time! Tgunn43@gmail.com

Lichens in general are not harmful to trees or in your case the vines.
Opening up the vines to improve air circulation can certainly help.
