The Adonis Monstera captivates with its distinctive fenestrated leaves. Its unique appearance, with natural holes or “windows,” makes it a popular choice for indoor plant enthusiasts, adding a tropical aesthetic.
Understanding Adonis Monstera
Adonis Monstera is a specific form of Monstera adansonii, often called the ‘Narrow Form’. This houseplant belongs to the Araceae family and is native to the tropical forests of Central and South America. While Monstera adansonii has other variations, the ‘Narrow Form’ is distinguished by its elongated, tapering leaves with prominent, fully enclosed fenestrations. Unlike its “wide form” counterpart, which has broader, heart-shaped leaves, the ‘Narrow Form’ presents a flatter, more slender leaf profile. These holes give rise to its common nickname, the “Swiss Cheese Plant.”
Caring for Your Adonis Monstera
Light Requirements
Adonis Monstera thrives in bright, indirect light, essential for healthy growth and fenestration development. Placing the plant near an east or north-facing window is ideal, providing filtered light. If a south or west-facing window is the only option, diffuse light with a sheer curtain to prevent scorching or yellowing leaves from direct sun exposure. While it tolerates moderate light, lower light conditions may slow growth and result in less pronounced holes.
Watering Practices
Proper watering is important. The most common mistake is overwatering, which can lead to root rot. Allow the top 1 to 2 inches (2-5 cm) of soil to dry out completely before watering again. Water thoroughly until water drains from the bottom of the pot, and empty any excess water from the saucer. During cooler months, growth slows, requiring less frequent watering.
Soil and Potting
Adonis Monstera requires a well-draining, airy potting mix that retains moisture but prevents waterlogging. An ideal mix includes components for good aeration and drainage. A recommended blend consists of potting soil, orchid bark, perlite, and coco coir or fiber (e.g., 4 parts potting mix, 2 parts orchid bark, 2 parts perlite, and 1 part coco coir). This plant prefers a slightly acidic to neutral pH, between 5.5 and 7.
Humidity and Temperature
As a tropical plant, Adonis Monstera appreciates high humidity, ranging from 60% to 80%. While it tolerates average household humidity, increased moisture contributes to a healthier plant. To boost humidity, use a room humidifier, pebble tray, or group plants to create a humid microclimate. Misting leaves offers temporary humidity. The plant thrives in warm temperatures, between 18°C and 27°C (65-80°F). Avoid sudden temperature changes and keep the plant away from cold drafts or direct heat sources, as fluctuations can stress the plant.
Fertilizing Needs
During its active growing season (spring and summer), Adonis Monstera benefits from regular fertilization. Use a balanced, water-soluble fertilizer (e.g., 10-10-10 or 20-20-20), diluted to half-strength. Apply monthly to support healthy leaf growth and strong root development. Before applying fertilizer, water the plant to prevent root burn. During fall and winter, when growth slows, reduce fertilization to once every two to three months or discontinue it to avoid salt buildup.
Support and Pruning
Adonis Monstera vines; support encourages climbing, leading to larger leaves and more pronounced fenestrations. Support options include moss poles or trellises. Pruning helps maintain the plant’s shape and height, and encourages bushier growth. Pruning is best performed during the growing season. Removing older, yellowing, or leggy growth redirects energy towards new, healthier foliage.
Repotting Your Plant
Repotting every one to two years is recommended for root expansion and to replenish soil nutrients. Spring and summer are the best times for repotting, during its active growing phase. Signs that your plant may need repotting include roots emerging from drainage holes or appearing on the soil surface, or if the plant dries out quickly. When repotting, choose a pot only one size larger to avoid overpotting. Carefully remove the plant, gently loosen tangled roots, and place it in the new pot with fresh, well-draining soil. After repotting, water the plant thoroughly and place it in a bright, indirect light location to minimize transplant shock.
Propagating Adonis Monstera
Propagating Adonis Monstera is achieved through stem cuttings, best undertaken during warmer growing months (spring or summer). To prepare a cutting, select a healthy stem and cut just below a node with clean, sharp scissors or a knife. Each cutting should include at least one to two nodes, as these are the points from which new roots will emerge. Remove any lower leaves that would be submerged in water.
Rooting in Water
For water rooting, place the cutting in a glass with submerged nodes, changing water weekly to keep it fresh.
Rooting in Soil
For soil propagation, plant the cutting in moist soil or sphagnum moss, ensuring the nodes are buried. Maintaining high humidity around the cuttings, perhaps by covering them with a plastic bag, can promote faster rooting. Roots begin to form within a few weeks, and new leaf development signals successful rooting.
Troubleshooting Common Issues
Adonis Monstera can exhibit common issues, often pointing to environmental imbalances. Yellowing leaves indicate improper soil moisture (most commonly overwatering), underwatering, or insufficient light. If soil remains wet, root rot may occur, requiring immediate repotting with fresh, well-draining soil and trimming affected roots. Conversely, limp, dry, or crispy leaf edges suggest underwatering or low humidity.
Browning leaf tips or crispy edges are a symptom of low humidity or inconsistent watering. Increasing ambient humidity through humidifiers or pebble trays can alleviate this. Leggy growth, where stems become elongated with sparse foliage, points to insufficient light, and relocating the plant to a brighter, indirectly lit spot encourages more compact growth.
Pest infestations are a concern, with common culprits including spider mites, mealybugs, and scale insects. These sap-sucking pests cause yellowing or speckled leaves and stunted growth. Inspecting the undersides of leaves and crevices regularly aids early detection. Treatments include wiping affected areas with rubbing alcohol, applying neem oil, or using insecticidal soap.
