If your Pilea Peperomioides have developed brown spots, then it may be overwatered. Your Pilea is a succulent-like plant that does not like to be overwatered or have its leaves wet for a long time. Brown spots caused by overwatering will mainly be seen on the leaves, and after a while, the leaves will start to fall off.

How to Cure:

To make brown spots caused by overwatering go away, be sure that the top of the soil is dry before watering again and only water the soil, not the leaves. Also, make sure your Pilea Peperomioides is receiving proper drainage with a well-draining soil and proper pot selection. If there is a hole in the bottom of your pot, discard any leftover water present in the plant’s saucer after a few hours, and be sure to water less next time.

2. Lack of Water

Although Pilea Peperomioides does not like to be overwatered, it still needs to be adequately watered. Pilea leaves may have yellow spots and droop if it needs to be watered.

How to Cure:

To remove the brown spots caused by lack of water, simply add water to the soil. Remember to feel the soil before adding the water. Only add water if the soil is dry. You can also feel the leaves to see if they are hard & thick, or soft and thin. If your plant needs water, the leaves will be thin.

Pilea Peperomioides need plenty of sunlight in order to thrive, especially as they begin to grow larger. You will know if your Pilea is not receiving enough sunlight when it becomes “leggy” and changes the way it grows. The scientific term for this is etiolation. 

Another sign that your Pilea Peperomioides aren’t receiving enough sunlight can be found in the leaves. Normally, a Pilea grows large, round leaves. When it doesn’t receive enough light, the leaves will be much smaller than normal. If you are watering your Pilea Peperomioides correctly but notice the leaves are still curling, or cupping, upwards, then this can also be an indicator it’s not receiving enough light.

Make sure your plant is receiving plenty of indirect light. Put it near a sunny window, or lamp for a few hours a day, then move it back to where you usually keep it. Do not put it in direct sunlight for an extended period or while the leaves are wet, as the plant will become damaged.
