Pothos amplifolia, also known as Epipremnum amplissimum, is a popular tropical vine. It offers a distinctive appearance compared to common Pothos varieties. Its adaptable nature and straightforward care make it a manageable addition to indoor plant collections. Native to Southeast Asia, it thrives in warm environments, well-suited for homes.
Identifying Pothos Amplifolia
Pothos amplifolia distinguishes itself with unique physical characteristics. It features dark green, glossy, lance-shaped leaves that can grow several feet long. These elongated, narrow leaves may display a bluish-grey hue. While many Pothos varieties have heart-shaped leaves, Pothos amplifolia’s distinct elongated shape sets it apart.
When provided with climbing support, such as a moss pole, its leaves can transform, becoming larger, wider, and more paddle-shaped, reaching up to 60 cm long. This shingling or climbing growth habit differs from the common Epipremnum aureum (Golden Pothos), which typically trails or climbs with smaller, heart-shaped leaves. Unlike Epipremnum pinnatum, which often develops lobed or fenestrated leaves as it matures, Pothos amplifolia maintains its elongated, entire leaf shape, simply increasing in size.
Pothos Amplifolia Care
Light
Pothos amplifolia adapts to various light conditions. It thrives best in medium to bright, indirect sunlight. Placing it near an east or west-facing window provides ample bright light without harsh direct sun, which could scorch its leaves. While it tolerates lower light, growth may slow, and the plant may produce longer, leafless stems.
Water
It has moderate watering needs, especially in warmer temperatures and good light. Water thoroughly, allowing water to drain from the bottom of the pot. Allow the top 2 inches of soil to dry out before the next watering. The plant may show signs of thirst by slightly drooping leaves. Overwatering can lead to yellowing leaves or root rot.
Soil
Pothos amplifolia is not particular about its potting mix, but a well-draining blend is beneficial. An ideal mix provides a balance of aeration and moisture retention. Many houseplant or aroid-specific mixes work well, often containing components like coco coir, orchid bark, perlite, and peat moss. Heavy soils that retain too much water should be avoided to prevent root rot.
Temperature and Humidity
Pothos amplifolia prefers warmer temperatures, typically between 65°F (18°C) and 85°F (29°C). It is not cold tolerant; protect it from drafts and keep it indoors below 50°F (10°C). While it adapts to average household humidity, it prefers higher humidity, ideally between 40-60%. If indoor air is too dry, especially during winter, a humidifier can help maintain adequate humidity.
Fertilizer
Pothos amplifolia does not require heavy feeding, but regular fertilization during its active growing season supports healthy growth. During spring and summer, a balanced liquid houseplant fertilizer applied every 4-6 weeks is sufficient. Diluting liquid fertilizers to half strength prevents over-fertilization and salt buildup in the soil. During fall and winter, when growth slows, reduce or stop fertilizing.
Pruning
Pruning Pothos amplifolia maintains its shape and encourages a fuller, bushier appearance. It involves removing excess growth or leggy stems. The best time for significant pruning is during the active growing season, from spring to early fall. Cuts should be made just below a leaf node using clean, sharp scissors or pruning shears. Regular trimming prevents the plant from becoming too spindly and promotes new growth from the nodes.
Propagating Pothos Amplifolia
Propagating Pothos amplifolia is straightforward, with stem cuttings being a common method. To propagate, select a healthy stem and make a cut about 4 to 6 inches long, ensuring it includes at least one node and a few leaves. Removing the lowest leaf from the cutting helps prevent rot if placed in water.
Cuttings can be rooted in water or directly in moist soil. For water propagation, place the cutting in a jar of room-temperature water, ensuring the node is submerged but leaves are above the water line. Roots typically emerge within a few weeks. If rooting in soil, plant the cutting in a well-draining, pre-moistened potting mix, and maintain consistent moisture. Once roots are several inches long, the rooted cutting can be transplanted into a larger pot.
Common Problems with Pothos Amplifolia
Pothos amplifolia may encounter common issues, often environmental. Yellowing leaves often indicate overwatering, especially if the soil remains consistently wet, or prolonged underwatering or nutrient deficiency. Adjusting watering frequency and checking soil moisture resolves this.
Brown leaf tips or edges suggest low humidity, underwatering, or excessive fertilizer salts. Increasing humidity with a humidifier or ensuring consistent watering helps. Drooping leaves are a clear sign of thirst. Pothos plants are generally resistant to pests, but occasional infestations of common houseplant pests like spider mites or mealybugs may occur. Regular inspection and appropriate treatment, such as neem oil or rubbing alcohol for localized issues, manages these problems.
