I have rooted lots of plants and shrubs like Oleander. Now I am trying to
get some orange tree cuttings to root. I cut off a growing branch end
several inches long at a diagonal, and remove the leaves. Then I dip the
freshly cut end in rooting hormone powder, then stick it in a 6 in pot with
miracle gro, sand, peat moss. They all are turning completely black, like
they are surely dead.
How do you get these rooted?
