Money Tree White Spots: Causes & Treatment
The Money Tree is a popular houseplant known for its braided trunk and lush green leaves. It’s generally easy to care for, but occasionally you may notice white spots appearing on the leaves. These spots can spread quickly, affect the plant’s appearance, and eventually cause leaf damage if left untreated.
Don’t panic. In this guide, we’ll explain why white spots appear on Money Tree leaves and how to fix the problem. Let’s get started.
What Causes White Spots on a Money Tree
White spots are a way your money tree tells you that it is in trouble. Here are some common reasons why white spots appear on your money tree's leaves. You can determine the cause based on your specific situation.
Powdery Mildew
The most common cause of white spots on money tree leaves is powdery mildew, a fungal disease that affects many indoor plants. It starts as white spots that look like flour sprinkled on the leaves, and soon the entire surface turns powdery. The fungus blocks sunlight, interfering with photosynthesis. Over time, affected leaves may turn yellow, curl, or weaken.
Sunburn
Unlike powdery spots, sunburn manifests as bleached, faded, or brownish-white patches on the side of the leaves facing the sun. Like most houseplants, the money tree prefers bright, indirect sunlight rather than direct sunlight. Strong afternoon sunlight can scorch the leaves, often resulting in pale spots and browning along the edges.
Mineral Residue
White spots are sometimes simply mineral deposits left behind by tap water. When water droplets dry on a leaf, minerals such as calcium and magnesium are left behind, creating white spots or ring-shaped marks. This mineral residue is usually harmless. However, if the spots are accompanied by brown leaf tips, you need to pay attention, as it is a sign of excess mineral buildup.
Pest Infestation
Small insects, such as mealybugs, thrips, and leaf miners, feed by sucking sap from plant tissues. They pierce the plant's tissues and suck the sap. In this process, they often leave white residue, waxy coatings, or sticky honeydew on the leaves. You may also notice yellowing or distorted foliage.
Nutrient Deficiency
Deficiencies in nutrients such as iron, magnesium, or copper can disrupt chlorophyll production. As a result, the leaves may develop light-colored patches, faded spots, or uneven discoloration instead of a healthy green color. This problem is more likely to occur if the plant has been growing in the same soil without fertilization for a long time.
How to Get Rid of White Spots on a Money Tree
Once you identify the cause of the white spots, you can take the right steps to fix the problem. Here is how to treat each common cause.
How to Fix Powdery Mildew
If your money tree has powdery mildew, isolate the plant to prevent the fungus from spreading to other plants. Wipe the affected leaves with fungicidal soap or a mix of neem oil, liquid soap, and water. For more serious infections, apply a fungicide according to the label instructions. Improving air circulation and keeping the leaves dry can prevent fungal growth.
How to Fix Sunburn
If the white spots are caused by sunburn, move the plant to a location with bright, indirect light, such as an east-facing window or a spot a few feet away from a south- or west-facing window shielded by a sheer curtain. The whitened parts will not turn green again, so it is best to prune them off so the plant can focus on recovery.
How to Fix Mineral Residue
If the spots are caused by mineral residue, simply wipe the leaves with a damp cloth to remove the deposits. However, if you also notice brown leaf tips, it indicates excessive minerals in the tap water. In this case, stop watering with tap water and switch to filtered water, distilled water, or rainwater to reduce salt accumulation.
How to Fix Pest Infestation
If pests are the cause, inspect the plant carefully, especially the undersides of leaves and where the leaves meet the stems. Remove visible insects using a cotton swab dipped in rubbing alcohol. Then spray the plant with insecticidal soap or neem oil once a week until the pests are gone. Regular inspection and keeping the plant clean help prevent future infestations.
How to Fix Nutrient Deficiency
If the problem is caused by nutrient deficiency, feed the plant with a balanced liquid houseplant fertilizer during spring and summer. Repotting the money tree in fresh, well-draining soil every year or two can also help restore nutrients and support healthy growth.
Conclusion
White spots on a money tree may look alarming, but they are usually caused by a few common problems. Once you identify the cause, the issue is often easy to fix with proper care.
Regularly inspecting your plant and maintaining good growing conditions can help prevent most of these problems. If white spots do appear, addressing the cause early will help your money tree recover.
