Pothos, scientifically known as Epipremnum aureum, is a popular tropical vine prized for its hardiness and attractive foliage. Native to the Solomon Islands, it thrives in warm, humid environments with indirect light. While commonly grown as a houseplant, its adaptability raises the question: can it survive outdoors?
Pothos can live outside only in specific climates. It thrives in USDA hardiness zones 10–12, where temperatures remain above 50°F (10°C). Frost or prolonged cold will damage or kill the plant. In cooler regions, it can be grown outdoors seasonally but must be brought indoors before temperatures drop.
While pothos tolerates low light indoors, outdoor conditions require careful light management. Bright, indirect light is ideal—direct sunlight, especially in hot climates, can scorch leaves. A shaded patio or under a tree canopy mimics its natural rainforest habitat. In northern climates, morning sun with afternoon shade works well.
Outdoor pothos needs well-draining soil to prevent root rot. Amend garden soil with perlite or compost for better drainage. Watering frequency increases outdoors due to wind and sun exposure. Keep soil consistently moist but not soggy, reducing water in cooler months to avoid overhydration.
Pothos prefers humidity levels of 50–70%, which outdoor environments often provide naturally. However, in arid regions, misting or placing the plant near water features helps. Ensure adequate airflow to prevent fungal diseases, but avoid windy spots that may dehydrate leaves.
Outdoor pothos may encounter pests like aphids, mealybugs, or spider mites. Regularly inspect leaves and treat infestations with insecticidal soap. Overly wet conditions can invite root rot or leaf spot. Proper spacing and avoiding overhead watering reduce disease risks.
Pothos vines can grow aggressively outdoors, reaching lengths of 20–40 feet. Provide a trellis, fence, or tree trunk for support. Prune regularly to control growth and encourage bushiness. Without support, vines may become invasive in warm climates.
In temperate zones, move pothos outdoors only after the last frost. Gradually acclimate it to outdoor light over 1–2 weeks ("hardening off"). As autumn approaches, reduce watering and relocate the plant indoors before nighttime temperatures dip below 50°F (10°C).
Growing pothos in containers outdoors offers flexibility. Use pots with drainage holes and lightweight soil. Ground planting is viable in frost-free areas but may require root barriers to prevent overgrowth. Containers simplify overwintering in colder climates.
Outdoor pothos often exhibits larger leaves and faster growth due to optimal light and humidity. It can also serve as a natural ground cover or decorative vine. However, monitor growth to prevent it from overtaking other plants or structures.
