The video was part of a Jerry Baker's Master Gardener series... It
was presented as something you just do as regular maintenance; as a
Best Practice in landscape care. His premise appears to be that
stopping diseases and insect problems before they start by using safe
non-toxic preventative care, is better than reactively treating once a
problem appears.

Eeeew. This person sounds like they belong to the "Nuke it till it Glows"
Brigade.

If you start on this journey, you will always have to do it all the time as
you will kill all the good insects in your garden and if you stop the
nasties arrive and may do a lot of damage before the natural predators can
build up their numbers to counteract them. If you garden organically, you
might occasionally have problems but the goodies and the baddies generally
balance each other out (and it's less work).
