Snow is around the corner here and I'm wondering what else I should do to prepare my trees for winter. I've cleared out all the leaves to suppress pestilence. I bought a bottle of dormant oil but I haven't yet applied it as I'm a bit hesitant about  overdosing. I had read some posts earlier about applying an organic clay-based elixir to the trunk, is that recommended?

What do other people here do to winterize?
