Pothos (Epipremnum aureum), also known as devil's ivy, is a popular houseplant renowned for its rapid growth and adaptability. Under optimal conditions, pothos can grow up to 12 inches (30 cm) per month during its active growing season (spring and summer). However, growth rates vary depending on environmental factors, care practices, and the plant's age.
Several factors determine how fast a pothos plant grows:
Light: Bright, indirect light accelerates growth, while low light slows it down. Pothos can tolerate low light but grows more slowly and may produce smaller leaves.
Temperature: Ideal temperatures range between 65°F–85°F (18°C–29°C). Growth slows below 50°F (10°C).
Watering: Consistent moisture (without overwatering) promotes faster growth. Drought stress or waterlogging can stunt growth.
Soil and Fertilization: Well-draining soil and monthly fertilization during the growing season boost growth.
Humidity: Higher humidity (60% or more) encourages faster growth, though pothos adapts to average household humidity.
Juvenile Phase: Young pothos plants focus on root and vine development. Growth may appear slower initially as the plant establishes itself.
Mature Phase: Once established, pothos enters a vigorous growth phase, producing long vines and larger leaves. In ideal conditions, vines can grow several feet in a single season.
Spring and Summer: Pothos experiences its peak growth during these warmer months, with vines extending rapidly and new leaves unfurling weekly.
Fall and Winter: Growth slows or pauses due to reduced light and cooler temperatures. Overwatering during dormancy can harm the plant.
Different pothos cultivars grow at slightly varying speeds:
Golden Pothos: The most common variety, known for fast growth (up to 12 inches/month).
Marble Queen Pothos: Slower growth due to variegation, which reduces chlorophyll.
Neon Pothos: Moderate growth rate, with vibrant yellow-green leaves.
Jade Pothos: Grows faster in low light compared to variegated types.
To ensure your pothos grows as quickly as possible:
Prune Regularly: Trimming leggy vines encourages bushier growth and redirects energy to new shoots.
Provide Support: Training vines on a moss pole or trellis promotes larger leaves and faster vertical growth.
Repot When Rootbound: Refreshing the soil and providing more space prevents growth stagnation.
Avoid Pests: Spider mites or mealybugs can slow growth. Inspect leaves regularly.
