listen to what Dom has typed.
with that said ....
the questions i asked were to isolate cause of death or indications.
usually if a cutting is rubbery, it's wet, if it breaks, it's dry. with that said, i've noticed the rotted cuttings typically can be bent into several circles if you really want to (almost like rubber), and the outer layer just develops cracks, it's really weird.
if you have a cutting to spare, cut it in half between the nodes. the "pith" in the center should be white and spongey, almost like styrofoam. if it's any color other than snow white, and it's any texture other than fresh whipped cream, then there's probably a problem (death). it should smoosh with the touch and not return to fluffiness. it's pretty miraculous that way.
for roots, see post #12 in this thread: http://figs4funforum.websitetoolbox.com/post?id=5137807
about the pulling apart tidbit on roots, a healthy root shouldn't break with light pressure, whereas a rotten root will break with no tugging at all. however, a dead and dry root can be pretty damned tough. that's a tough one to explain with words, more of an experiencial thing.
for smells .... curiousity more than anything. a healthy tree/cutting roots smells like cocounut milk to me, very, very sweet smell. dead cuttings smell somewhat sour to me. i'm a freak though, what some people call a "super smeller", so you may not experience the same things as me with smell. Figs usually smell like one of two things on the top: cat urine or coconut milk, and they usually smell like coconut milk under the soil.
i would never indicate i have the "right answers" to anything. i'm only sharing my experience, which could be a truckload of manure, or may be on-point. it's important to remember that observations are not fact they're just observations. a lot of what i share is simply observation, which can be a learning tool for many.
I am not a "fig guru". i will leave that to a few of the older, veteran members here.
