I received a plumeria cutting (shown in the photo) from a friend last summer. He put root toner on it, potted it, and gave it to me. This is how he has planted all of his plumerias and has had GREAT success. HOWEVER, I have taken care of this one that he has given me just like the others and it still doesn't look right. Feels slightly mushy, but I'm not sure...All of the others have leaves and or flowers on them at this point. However, this one has nothing. should I attempt to pull it out of the dirt to see if it has even rooted? What should I do otherwise? If anything.
