Money trees (Pachira aquatica) are popular houseplants, known for their braided trunks and vibrant foliage. If your money tree’s leaves are turning brown, it often signals underlying issues, from environmental stressors to care imbalances. Careful observation is needed to diagnose and address the problem.
Common Reasons for Browning Leaves
Watering issues are a common cause of browning leaves. Underwatering leads to dry, crispy brown tips and edges as the plant struggles to transport moisture. If the soil is completely dry and leaves are brittle, water thoroughly to rehydrate the plant.
Conversely, overwatering often results in soggy, dark brown, or mushy leaves and can lead to root rot. Waterlogged soil deprives roots of oxygen, causing decay and preventing nutrient absorption. To address this, unpot the money tree, inspect roots, and trim any soft, black sections before repotting into fresh, drier soil.
Inadequate light exposure also contributes to leaf browning. Too much direct sunlight can scorch leaves, causing crispy brown spots or discolored patches. Move the plant to bright, indirect light to prevent sun damage. Insufficient light weakens the plant, making it susceptible to stressors that cause overall browning. Adjust its position to a brighter, indirect light source for recovery.
Low humidity levels, common in dry indoor environments, lead to dry, crispy brown leaf tips and edges. The plant loses moisture through its leaves faster than its roots can supply it. Misting regularly or placing the pot on a pebble tray filled with water increases localized humidity around the plant.
Sudden temperature fluctuations or cold drafts can cause leaves to brown and drop. Money trees prefer stable environments; abrupt changes stress the plant. If your money tree is near a drafty window, air vent, or exterior door, relocate it to a sheltered spot with consistent temperatures.
Other Potential Causes of Browning Leaves
Nutrient imbalances, from deficiencies to excesses, can also cause money tree leaves to brown. A lack of nutrients leads to yellowing that progresses to browning. Conversely, excess salts from over-fertilization can burn leaf edges. Flush the soil with plain water until it drains freely to remove built-up salts, then adjust the fertilization schedule.
Pests and diseases can also cause leaf damage and browning. Common pests like spider mites and mealybugs feed on plant sap, causing discoloration, stippling, and browning. Inspect the undersides of leaves and stems for tiny insects or sticky residue. Treat affected areas by wiping leaves with a damp cloth or applying insecticidal soap. Fungal issues, such as leaf spot, can also appear as brown lesions.
A severely root-bound money tree or one in poor-quality soil struggles to absorb water and nutrients, leading to browning leaves. Constricted roots or compacted, nutrient-depleted soil hinder uptake. Remove the plant from its pot to assess the root system for root-bound conditions. If so, repot into a slightly larger container with fresh, well-draining potting mix.
Transplant stress is a common reason for temporary leaf browning after repotting or moving a money tree. This shock occurs as the plant adjusts to its new environment and disturbed root system, disrupting water absorption. Provide a stable environment with consistent light and humidity to help the plant recover.
Preventative Care for a Healthy Money Tree
Proper watering prevents browning leaves. Allow the top two to three inches of soil to dry completely between waterings. Then, water thoroughly until it drains from the bottom of the pot.
Provide ideal light conditions. Money trees thrive in bright, indirect light, like near an east-facing window. Consistent exposure supports photosynthesis and vibrant foliage.
Ensure adequate humidity for long-term health. Regular misting, grouping plants, or using a humidifier maintains consistent moisture levels. This prevents crispy leaf tips.
Maintain stable temperatures. Money trees prefer consistent temperatures between 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius). Keep them away from cold drafts from windows or air conditioning vents to reduce stress.
Follow appropriate fertilization guidelines. During the active growing season, feed your money tree with a balanced liquid houseplant fertilizer diluted to half strength every two to four weeks. Reduce or stop fertilization during dormant winter months.
Repot your money tree every two to three years, or when roots emerge from drainage holes or circle the pot. Choose a pot one to two inches larger in diameter than the current one. Use a fresh, well-draining potting mix.
