1. Prevent Overwatering
It is easier than you might think to avoid overwatering. The first thing to know is your plant. All plants have different watering habits. A snake plant requires much less water than a parlor palm. Make sure to follow the care instructions for your specific plant, and stick to that schedule of watering.
One important tip is to use a pot with drainage holes. These holes allow excess water to leave so that your plant is not sitting in soggy soil. Without drainage, water tends to collect at the bottom of the pot, which might lead to root rot. So, always pick a pot that lets the extra water flow out.
