Peperomia Leaves Turning Black
Peperomia leaves turning black can be alarming and can mean that your plant is in serious trouble. Don’t worry, this doesn’t necessarily mean that you’ve lost your Peperomia but it does mean you need to act fast to save it as black leaves can be a big sign that something is seriously wrong.
The main cause of Peperomia leaves turning black is overwatering or an issue with too much water staying trapped in the soil. Peperomia do not like to be watered too frequently. They store a lot of water in their leaves and when they are exposed to excess water they can develop rot very quickly. It’s incredibly important that you allow the soil to dry out between waterings to avoid this. You can monitor this by inserting a finger into the soil to see if its dry, getting used to the weight of the pot both wet and dry or using a moisture stick to help you.
You might find that you’re waiting for the soil to dry out but it is taking weeks and the problem is persisting. If this is the case then you may have an issue with your potting mix or drainage. Water needs to be able to run freely through the soil and excess water needs to be able to leave via the drainage hole. If your pot doesn’t have a drainage hole then the roots will be sitting in water for a long time which could be the cause of your Peperomia leaves turning black.
Another problem could be that the potting mix you’re using is too heavy and is retaining water. You should not be using compost or outdoor soil for indoor plants. And a Peperomia especially needs a light well draining mix. Try adding perlite to your mix to help aerate the soil and can an eye on the moisture levels. Is the soil taking two weeks or more to dry out? This could be a sign that the mix is too heavy or that the plant isn’t getting enough light or is in an area that is too cold.
Remember that you will need to water this plant a lot less during the winter months as the plant will use less water and will take longer to dry out. If your plant is receiving less light or is in a cold or humid environment then it is likely that it will need watering less and if it’s not drying out you may need to move your plant to a sunnier spot.
Hopefully this has helped you to not only solve the mystery of why are your Peperomia leaves turning black but also it’s given you an idea of what you can do to help prevent this from happening in the first place and also what you can do to fix it.
