Pachira aquatica, commonly known as the Money Tree, is a popular indoor plant that can also thrive outdoors in suitable climates. While it adapts well to consistent indoor environments, moving it outside requires careful consideration of temperature fluctuations. Understanding its specific temperature needs is important for maintaining its health and vibrant appearance. This article covers ideal outdoor temperature ranges and how to manage cold and hot weather.
Understanding Money Tree Temperature Needs
Money Trees prefer a consistent, warm outdoor environment. The ideal temperature range for vigorous growth is 65°F to 75°F (18°C to 24°C). Temperatures within this range support healthy leaf development and plant vitality. Exposure to temperatures outside this comfort zone can stress the plant.
These plants are sensitive to significant temperature drops. While they tolerate brief periods down to about 50°F (10°C), sustained temperatures below this threshold lead to chilling injury. Damage, such as leaf discoloration or drop, appears when temperatures consistently remain below 45°F (7°C).
Protecting from Cold Weather
Protecting a Money Tree from cold is important when outdoor temperatures fall. Signs of cold stress include wilting, browning leaf edges, or a limp appearance. Frost, which occurs when temperatures drop to 32°F (0°C) or below, causes damage to the plant’s foliage and stems.
Bringing the Money Tree indoors is the most reliable protection once nighttime temperatures consistently dip below 50°F (10°C). For brief cold snaps, cover the plant with a frost cloth or burlap. This helps trap ground heat, offering protection against light frost. Placing the plant under a patio overhang or near a warm wall also provides shelter from cold winds.
Protecting from Hot Weather
High temperatures present challenges for outdoor Money Trees. Prolonged exposure to heat, especially with intense sunlight, leads to heat stress. Symptoms include wilting leaves that may curl or develop scorched brown spots. Insufficient humidity in hot conditions exacerbates these issues.
Providing adequate shade is a defense against heat stress. Move the plant to a location that receives only morning sun or dappled light throughout the day to prevent leaf scorch. Increasing ambient humidity, perhaps by grouping it with other plants or placing it near a water feature, is beneficial. Consistent watering is essential to ensure the soil remains adequately moist, helping the plant cope with increased transpiration rates.
Acclimation and Seasonal Care
Transitioning a Money Tree between indoor and outdoor environments requires a gradual approach to prevent transplant shock. In spring, once frost danger has passed and night temperatures consistently stay above 50°F (10°C), begin “hardening off.” This involves placing the plant outdoors for a few hours daily, gradually increasing exposure over one to two weeks. Starting in a shady, protected spot and slowly introducing more light eases this transition.
In autumn, monitor weather forecasts and bring the Money Tree indoors before temperatures become too cool. This proactive approach prevents the plant from experiencing damaging sudden cold snaps. Choosing an outdoor location that offers protection from strong winds and intense afternoon sun contributes to its well-being throughout warmer months.
