Dying Pilea depressa occurs for several reasons, and you need to control both light and water. Here are the common issues that can result in the death of your plant:
a. Make sure that your plant does not stay dry for too much or too little time. If you feel your plant is dry, check one inch of the topsoil before watering the plant. You can feel the moisture using your finer.
b. Do not over-water your plant, as it can result in root rot and damage to the entire plant with stunted growth.
c. Placing your plant in excessive light for too long can result in burning the leaves. Your plant can also die if set in indirect sunlight for a longer time.
d. Although these plants are resistant to pest attacks, they can result in death or stunted growth if these pests attack your plant.
