Jade plant bumps

Question

I have a very mature jade plant and lately it’s been developing these little brownish red bumps on the stems and underside of leaves. Does anyone know what these are?

Oh boy... Those are scale insects. These will have to be manually removed and then sprayed for after to kill any remaining eggs. I don't normally recommend products here, but in this case I will. These can be a nightmare to get rid of and they will kill your plant.

FoxFarm makes a product called "Force of Nature Miticide" and it is a very broad spectrum organic pesticide. (and it smells like garlic!) It comes in a concentrate, or a ready to use spray. It will do the trick.
