Most common plant care mistake

Do you know the most common mistake in plant care?  Overwatering. 

You can spot it before it kills your plant by watching for symptoms.  

The damage you see in the above leaf was caused by too much watering.

These two photos show an infected plant stem which also comes from overwatering.

Luckily, it's not too late for this plant. Cut off the affected stem & leaves with a sterilized scissors & reduce watering.

It may end up looking like this beautiful, healthy plant.
