Their study shows that as much as 10 percent of the foliage in a garden can be damaged by insects before the average gardener even notices. This is exciting news. It tells us that most gardeners do not have a zero tolerance of insects in the garden and that maybe, just maybe, the populations of insects that create 10 percent damage levels might be large enough to support communities of natural enemies so diverse and numerous that the foliage damage levels never exceed 10 percent. I believe this utopia will be easier to achieve when most plants in our gardens are native.
