One oft-shared piece of pruning advice is that covering a newly pruned area with tar, paint or varnish can inhibit the fungal organisms that will get into the new cut, leading to a diseased tree, shrub or plant. This myth has been circulating for some time, according to the experts at Fine Gardening. Unfortunately, there is no surefire way to prevent microscopic organisms from infiltrating a new cut.
