After flowering, growth virtually stopped. There were no more new leaves, and the single vine ceased to grow. This pattern continued for many months, which is never a good thing, and usually points to the dreaded root rot. It did continue to periodically flower though, but this can also be a plants last gasp at reproducing because of other troubles.
