How to Be Sure My Mandevilla Plant Is Completely Dead?

Zone 10a | mandevilla12 added on December 6, 2012 | Answered

I can't find any green whatsoever on 1 of my 2 potted mandevillas.  When I break a branch, there's no trace of green. It's a goner, right?

Yes, it does sound as if it's a goner. However, this article may help you determine that for certain: https://www.gardeningknowhow.com/plant-problems/environmental/how-to-tell-if-a-plant-is-dead-and-how-to-recover-an-almost-dead-plant.htm

It sure sounds like it. Sorry. ...We have a highly technical method of determining if a plant is indeed deceased..."snappy, bendy"! If you grasp the stem between both hands and try to put both ends together and it snaps, it's usually dead. (and I mean you can hear the snap). If it bends (flexes) before breaking, there is usually some life left in the plant. Of course, there is always scraping the bark to the cambium cell layer to check for vitality!
