Q.My money tree
I’ve had my Money Tree for seven or eight years and it’s now about six foot tall. Some of the leaves are getting a sticky sap on them. The plant isn’t dropping leaves and is very healthy. It hasn’t ever done that before and was just wondering if that was normal?

Sticky leaves are a certain sign of a pest infestation. The pests that can do this can be very small so they can be hard to spot. You will have the best chance to spot them on the underside of the leaves.
This article will help you with spotting them and getting rid of them:
