Q.Mandevilla completely died above ground
My Mandevilla completely died above ground here in Florida with a few nights of below 30 temps. When I pulled it out of the container, there are many, many bulbous roots. Any chance if I replant that the plant will revive? I see no evidence of new growth.
Are you sure your mandevilla is completely dead? Have you tried doing a scratch test on a small section of outer bark to see if there is any green in the underlying tissue? If you have and there was no green, I would then cut the stems 6 inches above the ground and take a "wait and see" approach. If the root system survived the cold weather (hopefully it did), in time you may see new growth.
