Our indoor white gardenia has a sticky substance on the plant stems. It looks like cobwebs. What should we do?

Sounds like spider mites may be the culprit. Here is an article or two that you may find helpful: https://www.gardeningknowhow.com/plant-problems/pests/spider-mite-detection-and-spider-mite-natural-control.htm

I also had that problem with my gardenia, it, to me was a mite, I purchased an indoor spray for plants and soaked it....I had to do this a couple of times before all the mites were gone. I actually washed my plant off with water before I sprayed it. hope this helps.....
