Hello everyone, I'm new to the vertical mulching thing and looking for some tips. I would like to add VM to my services as an alternative to fertilizing for rejuvenating old and sick trees. I would be using an 6" auger bit on a stihl drill. I would like to hear about other methods for applying and especially what kind of cocktails you guys use to backfill the holes. The local landscape supplier has garden compost for sale which is a mixture of peat moss, hay, cocoa bean hulls, cotton seed meal, and poultry litter. Also anyone been experimenting with mycorrhizae as part of the ingredients when VM? Thanks!
