The Monstera Dubia ‘Green Form’ is a sought-after plant known for its distinctive shingling growth habit, where its heart-shaped leaves lie flat against a climbing surface. Originating from Central and South American rainforests, this Monstera appeals to enthusiasts for its charming juvenile form and potential to transform into a larger, fenestrated plant at maturity.
Monstera Dubia Green Form Care
Light
The Monstera Dubia ‘Green Form’ thrives in bright, indirect light, mimicking its natural forest habitat. A north, north-east, or north-west facing window is suitable, or a grow light can promote consistent growth. Direct sunlight, especially harsh afternoon sun, can scorch its delicate leaves. Insufficient light slows growth and may cause leaves to lose variegation.
Watering
The Monstera Dubia prefers consistently moist soil but is susceptible to root rot if overwatered. Water when the top one to two inches of soil feels dry. Water thoroughly until excess water drains from the pot’s drainage holes. During winter, the plant’s growth slows, requiring less frequent watering.
Humidity and Temperature
Monstera Dubia thrives in warm, humid environments, native to tropical rainforests. Maintaining humidity levels above 60% is beneficial for its growth. If household air is dry, use a humidifier, pebble tray, or group plants together. The plant prefers temperatures between 65°F and 85°F (18°C to 29°C) and should be kept away from cold drafts or heating/cooling vents.
Soil and Potting
The Monstera Dubia requires a well-draining, aerated potting mix that also retains some moisture. An ideal blend includes orchid bark, peat moss (or coco coir), and perlite. This mix ensures proper drainage and aeration, preventing waterlogging. Choose a pot with adequate drainage holes. Repot every two to three years, or when roots emerge from drainage holes, to refresh the soil and provide ample space for growth.
Fertilizing
During its active growing season, Monstera Dubia benefits from regular fertilization. Apply a balanced liquid houseplant fertilizer, diluted to half strength, every two to four weeks. Avoid over-fertilizing, as this can lead to salt buildup and harm the plant. During fall and winter, reduce or cease fertilization as growth slows.
Encouraging Shingling Growth
The distinctive shingling growth of Monstera Dubia is a captivating feature. To encourage this habit indoors, provide a vertical climbing surface like a moss pole, wooden plank, or coir pole.
The plant’s aerial roots naturally seek out and attach to these surfaces. Gently training the young vine to adhere to the support can initiate the shingling process. As the plant climbs, its leaves will grow larger and press closely against the surface, showcasing the overlapping pattern. This support promotes shingling and contributes to the plant’s maturity, potentially leading to larger leaves.
Propagation
Propagating Monstera Dubia ‘Green Form’ is straightforward using stem cuttings. Select a healthy stem section with at least one leaf and one or more nodes. Nodes are where new roots and growth emerge. Allow the cut end to air dry for a few hours to prevent rot.
Cuttings can be rooted in water, sphagnum moss, or a well-draining potting mix. If using water, submerge the node while keeping the leaf above the waterline, changing water weekly. For sphagnum moss, dampen the moss and nestle the cutting’s node into it, ensuring consistent moisture. Once roots are one to two inches long, transfer the cutting to soil.
Common Problems and Solutions
Monitor your Monstera Dubia for signs of distress. Yellowing leaves are a common indicator, signaling problems like overwatering (leading to root rot), underwatering, nutrient deficiencies, or insufficient light. Adjust watering based on soil moisture and ensure adequate drainage.
Browning leaf tips or edges often point to low humidity or inconsistent watering. Increase ambient humidity with humidifiers or pebble trays, and maintain a consistent watering schedule. Stunted growth or smaller leaves may indicate insufficient light or lack of climbing support. Relocate the plant to a brighter spot or provide a moss pole for larger foliage. Pests like spider mites and scale insects can affect Monstera Dubia. Regular inspection and treatments like neem oil or insecticidal soap can manage infestations.
