Summary of things to use?

[PCgeekchick]

Can someone give me a breakdown on things like when to use Cinnamon, brown Listerine, Neem oil, etc?

For instance, if I cut off a shedding leaf of a Phal, should I apply cinnamon? Or to a Den can that I remove for propagating?

Also, does anyone do a routine maintenance spray to keep things in check? I don't have any problems currently, but want to make sure I'm doing the best I can, and learning.

I bought a spray from Hummert's called Flower Pharm. It's the Cinnamon Oil variety, says it treats Orchid pests, fungus and garden pests and is a miticide, insecticide & fungicide. Makeup is Cottonseed oil 1.5%, Cinnamon .10%, Rosemary .10% and inerts are food grade oleic acid, non-gmo canola oil, usp grade glycerin, carbonic acid monopotassium salt, grape juices 11.1%,, and water 87.2%. Thoughts?

Thanks to everyone in advance!
