Epipremnum aureum is a very common plant for home decoration, and it prefers shade, so it doesn't mind being watered excessively. This makes it a favorite choice for many新手 gardeners. However, many beginners have told me that their newly purchased Epipremnum aureum has spots on it. Some are yellow, is it sick? Today, let's talk about what to do if the newly purchased Epipremnum aureum has yellow spots.
1. Diseases of Epipremnum aureum
If there are black spots on the leaf surface of Epipremnum aureum, it indicates that the plant has leaf spot disease or root rot. If there are yellow spots, it is caused by insufficient light or excessive humidity. Besides diseases caused by light or watering, there may also be pest infestations. Epipremnum aureum is easily attacked by red spiders and scale insects, which can dilute the sap of the leaves and cause yellow spots.
2. How to prevent and treat
Black and yellow spots on the leaves should be treated separately with targeted treatment. For black spots, we first need to remove the leaves with black spots to prevent them from spreading to other leaves. Then, we should ensure good ventilation and lower the temperature to avoid creating a suitable environment for bacteria. To prevent pests, we can usually water with chili water or garlic water. This type of water with a stimulating odor can effectively reduce pest infestations. We can also spray the leaves with carbendazim to form a protective layer and prevent damage from diseases and pests.
If the indoor temperature is relatively low, we can place the plant near the balcony to increase sunlight, which is beneficial for reducing leaf yellowing. When watering normally, be careful not to get water on the leaves. Avoid using a shower method to water Epipremnum aureum and water directly into the potting soil.
What causes yellow spots on the leaves of Epipremnum aureum
If you find yellow spots on the leaf surface, this is usually not a disease and should not be treated with medicine blindly. First, place the Epipremnum aureum in a place with sufficient sunlight, but be careful to avoid direct sunlight, as this would be counterproductive. Then, open the window for ventilation and check the results after a week. If small yellow-brown spots appear after a few days and the surrounding area gradually turns yellow and expands, forming round or irregular-shaped lesions, you may need to spray some medication to treat the disease.
3. How to care for Epipremnum aureum
When caring for Epipremnum aureum at home, you can place it in a well-lit area near the balcony or south-facing bedroom. However, if the sunlight is very strong at noon, avoid direct sunlight. Epipremnum aureum likes water but should not be overwatered. Generally, water once every 3-5 days, making sure to water thoroughly each time, which is very good for the growth of Epipremnum aureum and makes the leaves more translucent.
Epipremnum aureum is not only easy to care for but also has a good effect on absorbing formaldehyde and xylene. If it's a newly decorated house, you can place several pots inside to absorb odors.
