Mandevilla - Knowledgebase Question

The leaves on my Mandevill are turning yellow and folling off. I can't understand it. I see new growth, five or six new vines all over but today I went out to the porch and there were yellow leaves all over it.

I'm not exactly sure what happened to your mandevilla. New growth is a good sign but yellowing leaves can indicate overwatering. I wonder if the yellowing leaves are on the oldest vines and they are ready to die off? Your question isn't clear to me whether the new stems are suddenly dying or the leaves on the old stems are turning yellow. If the yellowing is on the older stems, it is probably natural for this time of year. If the yellowing leaves are on the newer growth, overwatering, a sudden blast of cold air, or a disease can be responsible. Wish I could offer a solution but without more detailed information about your plant, I'd only be guessing.
