I can tell you what I would do !! First I squeeze the cutting from one end to the other ..It should be hard with no mush ..If it is hard I would cut the rooting end back until I got nice clean wood with white sap.If It were squishy in the center I would stick it with a pin and see what comes out..If it were rotton in the center I would cut the rot out depending on how long the cutting is ..Then once you have a good section Dry it for a week to 10 days and then stick it in your rooting media..
