Money trees (Pachira aquatica) are popular indoor plants admired for their braided trunk and lush foliage. While generally easy to care for, winter presents unique challenges that can lead to its decline. Understanding how seasonal changes affect this tropical species is important for maintaining its health and vibrant appearance during colder months.
Why Money Trees Decline in Winter
Money trees originate from warm, humid environments in Central and South America, making them sensitive to indoor winter shifts. Reduced natural light, due to shorter days and decreased sunlight, impacts photosynthesis and slows growth.
Indoor heating systems lower ambient humidity levels; money trees thrive in 50-60% humidity, but heated homes often drop below this. Additionally, temperature fluctuations from drafts or heating vents can shock the plant. These combined factors create a stressful environment, leading to decline.
Identifying Winter Stress in Money Trees
Recognizing early signs of winter stress can help save a money tree. Yellowing leaves are a common symptom, indicating overwatering, insufficient humidity, or inconsistent temperatures. Leaf drop also frequently signals stress from environmental changes or cold exposure.
Wilting or drooping leaves suggest improper watering or temperature extremes. Browning leaf tips or edges indicate low humidity. Stunted growth or a “leggy” appearance with long, thin stems and sparse foliage can point to insufficient light.
Winter Care for Money Trees
Light Adjustments
During winter, money trees require bright, indirect light to compensate for shorter daylight hours. Placing the plant near an east, south, or west-facing window provides suitable filtered light. If natural light is limited, supplemental grow lights can provide the necessary brightness. Regularly rotating the plant every week or two helps ensure all sides receive even light exposure, promoting balanced growth. Cleaning dust from the leaves with a damp cloth also improves light absorption.
Watering Practices
Adjusting watering is crucial in winter as the plant’s growth slows. Money trees prefer their soil to dry out somewhat between waterings. Water only when the top 50% to 75% of the soil feels dry to the touch, which might be every 2 to 3 weeks. When watering, do so thoroughly until water drains from the bottom of the pot, then promptly empty any excess water from the saucer to prevent root rot. Overwatering is a common problem in winter, so it is better to err on the side of underwatering.
Humidity Solutions
To counteract the dry air from indoor heating, increasing humidity around your money tree is beneficial. Money trees thrive in humidity levels between 40% and 60%. Placing the plant on a pebble tray filled with water allows evaporation to create a more humid microclimate. Using a small room humidifier nearby is another effective method to maintain consistent humidity. Grouping several plants together can also naturally boost ambient humidity as plants release moisture through transpiration.
Temperature Stability
Maintaining a consistent indoor temperature is important for money trees, as they prefer temperatures between 65°F and 85°F (18°C and 29°C). Avoid placing the plant near drafty windows, doors, or heating/air conditioning vents, as sudden temperature fluctuations can stress the plant and cause leaf drop. Temperatures below 50°F (10°C) can cause significant stress and be detrimental. Keeping the plant in a stable environment away from cold spots helps prevent damage.
Preventing Winter Decline
Proactive measures can significantly reduce winter-related issues for your money tree. Before colder temperatures arrive, gradually acclimatize the plant if it has been outdoors. This gentle transition helps the plant adjust to indoor conditions without sudden shock.
Before bringing any outdoor plants inside for winter, thoroughly inspect them for pests. This preventative check, using a magnifying glass to examine leaf undersides, can prevent infestations from spreading to other houseplants. Regular pruning of any dead or yellowing leaves also promotes better air circulation and reduces disease risk.
