Brown spots on your Chinese money plant is typically a sign of overwatering, which can be harmful to your plant if left untreated.
SIGNS TO LOOK OUT FOR
Brown spots and browning of the edges of leaves
Leaves may also begin to fall off
You should also check to see if there are any pests on your Pilea, as brown spots can sometimes instead be caused by pests
The most likely cause of brown spots beginning to appear on your Pilea is having received too much water. If it begins to show signs of spotting, you can give the soil a quick check to see if this is the case. If the soil is still moist, then you should try to avoid watering again until it has had a chance to dry out a bit — just snooze your watering notifications in Planta.
However, brown spots can also be the result of overexposure to the sun, or by overfertilizing/ using the wrong type of fertilizer.
If you think your Pilea may have gotten too much sun, you should move it to a shadier location in order to give it some time to recover.
Or, if it seems that the problem could be overfertilizing, hold off adding any more fertilizer for the time being. You should also check that the fertilizer you are using is definitely suitable for Pilea peperomioides. Receiving too much fertilizer, or using too harsh a fertilizer for your plant can be harmful as it can burn the roots of the plant, preventing it from being able to take up nutrients and water. It’s always better to lean more towards underfertilizing than overfertilizing, as it’s much easier to treat an underfertilized plant.
WHAT TO DO NOW
Firstly, you’ll want to establish how this problem occurred - you can check your watering schedule to see if it seems to have been more frequent than usual recently, and to see if any changes need to be made.
If the watering schedule seems okay but you still think the problem is overwatering, you should check the drainage of your pot. We always recommend using plant pots that have holes in the bottom, as this will allow any excess water to drain out. Always make sure to empty out any water that collects under the pot - you should never leave a plant standing in water.
Next, you can double-check that your Pilea is getting the right amount of light to suit its needs. Chinese money plants usually prefer the ‘part sun, part shade’ or ‘shade’ options in Planta, so try not to place it somewhere where it will be sitting in direct, full sunlight for long periods of time, as this will be too much for it, which can, in turn, cause heat stress. Additionally, it’s a good idea to ensure that there is a good amount of airflow around your plant.
If the leaves are significantly damaged, you can remove them entirely from the plant or just trim off the damaged parts, as these unfortunately won’t recover.
WHAT IF I’M STILL HAVING PROBLEMS WITH MY PILEA?
Sometimes, you can do all the above and your Pilea may still get spots on its leaves. This could be indicative of a different problem, such as pests, so you may want to check over your plant to be sure that it’s definitely free of infestation. If that’s the case, and you’re sure that it doesn’t have any pests, you can try repotting it into a larger pot - again, it should have drainage holes in the bottom - and add some fresh, new soil. This should hopefully get your Pilea peperomioides looking healthy again soon.
