The Dragon Tail Plant, also known by its botanical name Rhaphidophora decursiva, is a sought-after houseplant recognized for its striking foliage. Its leaves develop unique, deep lobes as they mature, creating a distinctive aesthetic appeal. This vining plant brings a touch of the tropics indoors, making it a popular choice for plant enthusiasts.
Unveiling the Dragon Tail Plant
Often called “Dragon Tail Philodendron” or “Monstera decursiva,” its correct botanical name is Rhaphidophora decursiva. It belongs to the Araceae family, like Philodendrons and Monsteras, leading to common confusion. This climbing plant has a robust, vining habit, using aerial roots to attach to surfaces.
Juvenile leaves are smaller, pointed, or oval. As the plant matures and climbs, its leaves develop deep fenestrations or splits, giving them a palm-like appearance and the “Dragon Tail” name. Mature leaves can exceed 3 feet in length in ideal conditions.
Essential Dragon Tail Plant Care
Bright, indirect light is important for Rhaphidophora decursiva, mimicking its natural forest canopy habitat. Direct sun causes leaf scorching, while insufficient light results in slower growth and a lack of fenestrations. Position the plant near a bright window, possibly with a sheer curtain to filter intense light.
Water when the top one to two inches of soil have dried out. A “soak and dry” method is effective: water thoroughly until excess drains, then allow to dry partially. Overwatering leads to root rot; underwatering causes browning leaf tips. Watering frequency decreases during cooler, dormant months.
A well-draining, airy soil mix is suitable for Rhaphidophora decursiva. A common blend includes houseplant potting soil, perlite, and orchid bark, often in equal parts, to ensure good aeration and drainage while retaining some moisture. Avoid dense potting soil to prevent compaction and root suffocation.
This tropical plant appreciates 50-60% humidity, though it tolerates average household levels. To increase humidity, use a pebble tray, group plants, or employ a room humidifier. Regular morning misting provides a temporary boost. Higher humidity can encourage faster growth and more pronounced leaf fenestrations.
The Dragon Tail Plant prefers consistent warm temperatures, generally 60-80°F (15-26°C). It is not cold tolerant; exposure below 50°F (10°C) can cause damage. Protect the plant from cold drafts and sudden temperature fluctuations.
During spring and summer growing seasons, Rhaphidophora decursiva benefits from regular fertilization. Apply a balanced liquid fertilizer, diluted to half strength, monthly or every two to four weeks. Reduce or stop fertilizing in fall and winter when the plant’s growth naturally slows.
Given its natural climbing habit, vertical support is important for Rhaphidophora decursiva. A moss pole or trellis allows the plant to climb, encouraging larger, more fenestrated leaves. Without adequate support, the plant may exhibit leggy growth or cease producing new leaves.
Propagating Your Dragon Tail Plant
Propagating Rhaphidophora decursiva is straightforward, primarily through stem cuttings. The best time is spring or summer when the plant is actively growing. Select a healthy stem section with one to two nodes (where roots and new growth emerge).
Using clean, sharp shears, cut just below a node. Remove any leaves from the lowest submerged node to prevent rot. Place the cutting in water, ensuring nodes are submerged, or directly into moist, well-draining soil.
Water propagation allows for visible root development in one to four weeks before transferring to soil. When rooting in soil, keep the medium consistently moist but not waterlogged. Warmth and humidity accelerate root formation. Once roots are at least one inch long (if water propagating), the cutting is ready for a potting mix.
Troubleshooting Common Dragon Tail Plant Problems
Yellowing leaves can indicate several issues. Overwatering is a common cause, leading to root rot, but also insufficient light or nutrient deficiency. Adjust watering frequency to allow soil to dry, or ensure adequate light.
Browning leaf tips or edges often point to low humidity or inconsistent watering. Increase ambient humidity using humidifiers or pebble trays. Ensure consistent moisture without waterlogging to prevent browning.
Leggy growth or lack of fenestrations indicates insufficient light. Move the plant to a brighter location with indirect light to encourage compact growth and characteristic splits. The absence of climbing support can also contribute to leggy growth and smaller leaves.
While generally robust, Rhaphidophora decursiva can be susceptible to common houseplant pests like spider mites, mealybugs, thrips, and scale. Regular inspection helps in early detection. For minor infestations, wash leaves or use insecticidal soap or neem oil.
Dragon Tail Plant Toxicity
Like many Araceae plants, Rhaphidophora decursiva contains calcium oxalate crystals. These crystals can cause irritation if ingested by humans or pets. Symptoms in animals may include oral irritation, drooling, pawing at the mouth, and difficulty swallowing. Place the plant out of reach of children and pets to prevent accidental ingestion.
