The money tree (Pachira aquatica), with its distinctive hand-shaped leaves and tolerance for indoor low light conditions, is a favorite houseplant. Popular Asian folklore associates this tropical plant with good fortune and financial success. It can be concerning when you notice your Money Tree Leaves Turning Brown. Does this mean your luck is changing? Not at all! It simply indicates your plant is trying to tell you something about its care. Understanding the reasons behind brown leaves is key to restoring your money tree’s vibrant green health. Plant care is rooted in science, not superstition. Let’s explore the common causes of brown leaves on money trees and how to bring them back to life.
Reasons Why Your Money Tree Leaves Are Turning Brown
Several factors can contribute to brown leaves on your money tree. Identifying the specific cause is crucial for effective treatment. Here are the most frequent culprits:
1. Underwatering: The Thirst Factor
Brown leaves, especially with dry, crispy edges, can signal that your money tree is dehydrated. When a money tree doesn’t receive enough water, the leaf edges will turn brown and become brittle. If underwatering persists, the entire leaf will eventually turn brown and drop off. Native to the wetland regions of Central and South America, and widely cultivated in water-rich areas like Japan and East Asia, money trees thrive with consistent moisture. Ideally, water your money tree weekly. Water slowly and thoroughly until excess water drains from the pot’s drainage holes, ensuring the entire root system is hydrated.
2. Overwatering: Too Much of a Good Thing
Ironically, overwatering can also lead to brown leaves on a money tree. Excessive watering deprives the roots of oxygen, causing them to suffocate and rot. This root rot hinders the plant’s ability to absorb essential nutrients from the soil. Consequently, the leaves will turn brown and eventually die. Proper watering technique is essential for a healthy money tree. Allow the top inch or two of soil to dry out between watering sessions. When watering, saturate the soil until water drains from the drainage holes, and promptly remove any accumulated water from the saucer to prevent the roots from sitting in water.
3. Pest Infestations: Tiny Sap-Suckers
Pests such as mealybugs and spider mites can cause browning leaves, particularly in advanced infestations. These minuscule pests feed on the plant’s sap, initially causing leaves to yellow before progressing to brown. Sometimes, the yellowing stage is subtle and you might only notice the brown leaves. Carefully inspect your money tree’s leaves, both top and bottom, for signs of pests. Mealybugs appear as small, cottony white masses, while spider mites are extremely tiny and may be identified by fine webbing on the leaves. If you detect pests, treat the entire plant with insecticidal soap or neem oil, ensuring thorough coverage to eliminate the infestation.

It’s advisable to prune away completely brown leaves. Once leaves are entirely brown, they cannot recover. Focus your efforts on nurturing the remaining healthy green leaves to facilitate the plant’s recovery.
4. Temperature Fluctuations: Drafts and Cold Air
Sudden shifts in temperature, especially exposure to drafts, can stress your money tree and result in brown leaves that may also drop off. Keep your plant away from drafty locations such as windows that are frequently opened or near heating and air conditioning vents. Sudden blasts of hot or cold air can shock the plant, leading to leaf browning. Position your money tree in a location with a consistent, moderate ambient temperature, away from direct drafts.
5. Fungal and Bacterial Diseases: Spotting the Infection
If you observe brown spots appearing on the leaves, it could indicate a fungal or bacterial infection. These pathogens flourish in moist, humid environments. If left untreated, these infections can destroy leaf tissue, causing brown spots to expand and merge. Treat infected leaves with a copper-based fungicide, following product instructions carefully. Isolate the affected money tree from other plants to prevent the potential spread of infection. To minimize the risk of fungal and bacterial issues, water your money tree at the base, directly onto the soil, avoiding wetting the leaves. Persistent moisture on leaves, especially if they don’t dry quickly, creates favorable conditions for fungal and bacterial growth.
6. Low Humidity: Dry Air Issues
Dry air, particularly during winter months when indoor heating systems are in use, can cause money tree leaves to turn brown. These tropical plants thrive in humid environments. While it might seem intuitive to mist the leaves, this practice is generally discouraged as it can increase the risk of fungal infections. A more effective solution is to use a humidifier. Place a humidifier near your money tree and other humidity-loving houseplants to ensure they are surrounded by consistently moist air, especially during dry seasons.

Will Your Money Tree Regrow Leaves?
In most instances, yes, your money tree is resilient and capable of producing new leaves. By addressing the underlying cause of the brown leaves and providing appropriate care, you can help your plant recover and flourish. This includes ensuring it receives adequate but not excessive water, the right amount of indirect light, and a balanced fertilizer during the growing season. Once your money tree regains its health, you should observe new growth emerging, signaling its successful recovery.
