Why Does my Cats Pajamas Plant Have Brown Spots?

Updated: April 29, 2022

If you’ve noticed brown spots on your Cat’s Pajamas plant, you’re not alone. This popular houseplant is known for its beautiful foliage and easy care, but it’s not immune to a few common problems. In this article, we’ll explore some of the reasons why your Cat’s Pajamas plant might be developing brown spots, and what you can do to prevent or treat the issue.


One of the most common causes of brown spots on Cat’s Pajamas plants is overwatering. These plants prefer well-draining soil and don’t like to sit in water. When the soil stays too wet for too long, it can lead to root rot and other issues that can cause brown spots on the leaves.

To prevent overwatering, make sure your Cat’s Pajamas plant is in a pot with drainage holes and use a well-draining potting mix. Wait until the top inch of soil is dry before watering, and don’t let the plant sit in standing water.


While overwatering can cause brown spots, so can underwatering. If your Cat’s Pajamas plant is getting too little water, its leaves may start to dry out and turn brown.

To prevent underwatering, make sure you’re watering your plant regularly and thoroughly. Don’t let the soil dry out completely between waterings, but also don’t keep it constantly wet.


Cat’s Pajamas plants prefer a humid environment and can develop brown spots if the air in your home is too dry. This is especially common during the winter months when indoor heating can dry out the air.

To increase humidity around your Cat’s Pajamas plant, try misting it regularly with a spray bottle or placing a humidifier nearby. You can also group several houseplants together to create a microclimate of humidity.


Pests like spider mites, mealybugs, and scale insects can also cause brown spots on Cat’s Pajamas plants. These pests feed on the plant’s sap, leaving behind small brown spots or discoloration.

To prevent pests, inspect your plant regularly for signs of infestation and take action if you notice any. You can use insecticidal soap or neem oil to treat most common houseplant pests.


Finally, disease can also cause brown spots on Cat’s Pajamas plants. Fungal diseases like leaf spot and bacterial diseases like blight can both cause brown spots on the leaves.

To prevent disease, make sure your plant is in a well-ventilated area and avoid getting the leaves wet when you water. If you notice signs of disease, remove affected leaves and treat the plant with a fungicide or bactericide as directed.


Can I save my Cat’s Pajamas plant if it has brown spots?

It depends on the cause of the brown spots. If it’s due to overwatering or underwatering, adjusting your watering habits may be enough to save the plant. If it’s due to pests or disease, you may need to take more aggressive action to save your plant.

How often should I water my Cat’s Pajamas plant?

Water your Cat’s Pajamas plant when the top inch of soil feels dry to the touch. This could be once a week or every few days depending on your home’s humidity and temperature.

Can I propagate my Cat’s Pajamas plant?

Yes! Cat’s Pajamas plants are easy to propagate from stem cuttings. Simply cut a stem with a few leaves and place it in water until roots form. Then, transplant the cutting into soil.

Can I keep my Cat’s Pajamas plant outdoors?

Cat’s Pajamas plants are not cold-hardy and should not be kept outdoors in temperatures below 50°F. They also prefer bright, indirect light, so keep them in a partially shaded area.
