Pothos (*Epipremnum aureum*) is a hardy tropical plant native to Southeast Asia, known for its adaptability to indoor environments. However, its temperature tolerance is influenced by its natural habitat, where it thrives in warm, humid conditions. The ideal temperature range for Pothos is between **65°F to 85°F (18°C to 29°C)**. Outside this range, the plant may exhibit stress symptoms such as slowed growth, leaf yellowing, or wilting.
In its optimal range, Pothos grows vigorously, producing lush foliage and long trailing vines. Temperatures below **50°F (10°C)** can cause cold damage, while prolonged exposure to temperatures above **90°F (32°C)** may lead to dehydration or scorched leaves. Maintaining consistent warmth is key, as sudden fluctuations can shock the plant.
During winter, indoor temperatures often drop, especially near windows or drafty areas. To protect Pothos:
Pothos communicates discomfort through visible cues:
Adjust the plant’s location promptly if these signs appear.
While temperature is critical, humidity also plays a role. Pothos prefers **40-60% humidity**, which mimics tropical conditions. In dry winter air, use a humidifier or pebble tray to maintain moisture levels, preventing leaf crisping without over-relying on temperature adjustments alone.
Avoid sudden shifts in temperature when moving Pothos between rooms or outdoors in summer. Gradually introduce the plant to new conditions over 1–2 weeks to minimize shock. For example, if relocating outdoors, start in a shaded area before exposing to indirect light.
If Pothos is exposed to extreme cold:
For heat stress, increase watering slightly and provide shade or misting.
Pothos tolerates low light but grows best in bright, indirect light. In cooler months, ensure adequate light exposure to compensate for reduced metabolic activity. Avoid placing the plant near heat vents, as direct hot air can dehydrate leaves rapidly.
