Q.Jade plant
It is oozing sticky liquid. Any idea why?
It could be caused by an injury to the plant (did something happen?) but most likely caused by pests. Look for signs of an insect infestation, possibly by aphids or mealy bugs, for example. The oozing sticky liquid is sap from the plant. The sap leaks out when the pests bite into the plant to feed.
Below are some articles on aphids and mealy bugs. There are photos in these articles for easy identification.
