Pothos (*Epipremnum aureum*) is a popular tropical vine known for its hardiness and adaptability as a houseplant. Native to the Solomon Islands and parts of Southeast Asia, it thrives in warm, humid environments with dappled sunlight. In its natural habitat, Pothos grows as an understory plant, climbing trees or spreading across the forest floor. Understanding its native conditions is key to determining whether it can survive outdoors in non-tropical regions.
Pothos can survive outdoors, but only under specific conditions that mimic its tropical origins. It is not frost-tolerant and will perish in temperatures below 50°F (10°C). In USDA hardiness zones 10-12, where temperatures remain consistently warm, Pothos can thrive outside year-round. In cooler climates, it can be grown outdoors during the summer but must be brought indoors before temperatures drop in fall.
To ensure Pothos thrives outside, the following conditions must be met:
Pothos prefers temperatures between 65-85°F (18-29°C). Avoid exposing it to temperatures below 50°F (10°C), as cold stress can cause leaf yellowing, wilting, or death.
While Pothos tolerates low light indoors, outdoor plants need filtered or indirect sunlight. Direct sun can scorch its leaves, so place it in a shaded or partially shaded area, such as under a tree or on a covered patio.
High humidity (60% or more) is ideal for outdoor Pothos. In dry climates, mist the leaves regularly or place the plant near a water source to increase humidity. Ensure well-draining soil to prevent root rot, but keep the soil consistently moist.
Several challenges may arise when growing Pothos outside:
Outdoor Pothos is more susceptible to pests like aphids, mealybugs, and spider mites. Regularly inspect the leaves and treat infestations with insecticidal soap or neem oil. Overly wet conditions can also lead to fungal diseases like root rot.
In temperate climates, Pothos cannot survive winter outdoors. As temperatures drop, the plant must be moved indoors or protected with frost cloths or mulch (though this is often insufficient in freezing conditions).
If moving Pothos outside for the summer, follow these steps to avoid shock:
Start by placing the plant in a shaded area for a few hours daily, gradually increasing exposure over 1-2 weeks. This helps the plant adjust to outdoor light and temperature fluctuations.
Pothos grows well in containers outdoors, allowing for easy relocation. If planted in the ground, ensure the soil is rich and well-draining. Note that ground-planted Pothos may become invasive in warm climates.
Outdoor Pothos may require more frequent watering due to wind and sun exposure. Check the soil moisture daily and water when the top inch feels dry.
When conditions are suitable, outdoor Pothos can grow larger and more vigorously than indoor plants. The increased light and airflow often result in thicker foliage and faster growth. Additionally, outdoor Pothos can serve as a ground cover or climbing vine, adding lush greenery to shaded garden areas.
