Sticky substance on leaves and stems, most sticky on lower leaves, top ones not affected yet. Plant reasonably healthy otherwise. Soil has mold or mildew on top, though soil is dry. Will repot plant in new soil, but what is the problem and how do I deal with sticky substance, which I presume is coming from this distressed plant? Thanks.

This is a sign that the plant has a pest infestation. Often the pests that secrete honeydew (which is the sticky substance) are hard to see. It may be aphids, scale or a few other pests. Treat the plant with a pesticide and you should see the sticky substance clear up as the pests die.
