Hello, I was wondering if anybody uses a fungicide to treat cuttings before using the bag method. I also have a few small trees that are growing and have mold on the tips. I had them in a "greenhouse". I have removed them to dry air. Is there anything else I need to do for them?

I would use a hair dryer in low heat and give them a good drying air.  blowing away from the other plants, of course. Only way to cure mold is to dry it out completely  soon you wet it, it comes back.

I have also read about cinnamon as an anti-fungal.....don't know though.  And its complicated by the fact that most powdered cinnamon is actually cassia, apparently.  Little dilute peroxide spray.......just stuff I heard...no empirical evidence though :(  pretty new....

I first scrub with a soft toothbrush and disinfectant dish soap,rinse, then spray them with peroxide or bleach diluted with water.  Then I let them dry!  The thing that causes mold is too much moisture in your rooting medium.
