Here is a photo of a cutting I am trying to start. Looks like little white bumps forming from ground level up about 1/2 inch on cutting, are these roots ? should I cover them with potting soil mix ?
I would say add to it. The odds are greater.
Did you spray the wood with some type of oil?
No, I have not sprayed oil on it, I do mist it with water once or twice a day. picture could have been taken after misting.
