Monterey Garden Phos
Hi: I have not used the Phos yet on my viburnum tree that woodpeckers have made holes in (trunk mainly). I believe the holes let in a fungus or illness to the tree. The Monterey Garden Phos was recommended on one of the MANY websites I looked at for fungus/illnesses common to viburnum. It was also affordable. I will try it and let you know; but it might take a 'while.' Thank you for packaging the Phos so carefully. I have had things open in the mail; and I've heard about it on reviews from other companies and websites about liquids in the mail. You guys ROCK!
