The Plerandra elegantissima, commonly known as False Aralia, is a popular indoor plant. Its delicate, lacy foliage and slender stems create an elegant, airy presence. This plant originates from the tropical Pacific Islands, particularly New Caledonia.
Creating the Ideal Environment
Light
False Aralia thrives in bright, indirect light. An east or north-facing window is ideal, or a few feet away from a south or west-facing window to avoid harsh light. Too little light can lead to leggy growth and dull foliage. Conversely, direct sunlight can scorch its delicate leaves.
Watering
False Aralia prefers consistent moisture, but avoid overwatering, which causes root rot. Allow the top inch or two of soil to dry out between waterings. Check soil moisture by inserting a finger. Yellowing leaves indicate overwatering, while underwatering may cause drooping or wilting.
Soil
False Aralia needs well-draining, aerated soil rich in organic matter. A standard potting mix amended with perlite or orchid bark enhances drainage and airflow, which is beneficial for root health. A peat-based mix is recommended, as it retains moisture. False Aralia prefers neutral soil conditions.
Temperature and Humidity
False Aralia prefers average room temperatures, between 65-85°F (18-29°C). It is sensitive to cold drafts and temperatures below 60°F (15°C), which can cause leaf drop. This plant also requires high humidity, around 50% or more. To increase humidity, place the pot on a pebble tray, use a room humidifier, or group plants together.
Fertilizing
During spring and summer, fertilize False Aralia every two to four weeks. Use a balanced liquid houseplant fertilizer diluted to half strength. Do not fertilize during winter when growth slows.
Ongoing Maintenance
Pruning
Pruning False Aralia helps maintain its shape, encourages bushiness, and removes dead or diseased foliage. As a slow grower, it does not require frequent pruning unless you want to control height or encourage a fuller appearance. When pruning, use clean, sharp secateurs and cut above a leaf node to promote new growth. The best time for significant pruning is in spring as the growing season begins.
Repotting
Repotting is needed every two to three years, or when the plant becomes root-bound. The best time to repot is during spring or early summer. Choose a pot one size larger with drainage holes. When repotting, gently remove the plant, loosen the roots, and place it in the new pot with fresh, well-draining soil mix.
Troubleshooting Common Problems
Pests and Diseases
False Aralia can be susceptible to pests like spider mites, mealybugs, aphids, and scale. Inspect the plant regularly for signs of infestation, especially on leaf undersides and axils. Organic control methods, such as insecticidal soap or neem oil, can treat these pests. Overwatering is the main cause of root rot.
Leaf Issues
Browning leaf tips or edges indicate low humidity or underwatering. Increasing ambient humidity and ensuring consistent watering can resolve this. Yellowing leaves are a sign of overwatering, but can also suggest a nutrient deficiency. Adjusting watering and ensuring drainage can alleviate yellowing from overwatering. Leaf drop can occur due to environmental stress, like sudden changes in temperature, light, humidity, or inconsistent watering.
