The Mandarin Spider Plant (Chlorophytum orchidastrum ‘Mandarin’) is a popular houseplant known for its vibrant green leaves and distinctive, bright orange stems. Its striking appearance and adaptability make it a favorite among plant enthusiasts.
Essential Care for Mandarin Spider Plants
Light
Mandarin Spider Plants thrive in bright, indirect light. An ideal spot is near a north or east-facing window, providing filtered sunlight. Direct, intense sunlight can scorch foliage and fade the orange stems. While the plants tolerate lower light, growth may slow, and stem color intensity might diminish.
Watering
Mandarin Spider Plants have low to average water requirements. Water when the top inch or two of potting mix feels dry. Overwatering causes root rot, so ensure the pot has drainage holes and excess water drains. Watering frequency varies, from every 5-7 days in warmer conditions to 7-12 days in cooler months.
Soil Requirements
Mandarin Spider Plants prefer a well-draining potting mix that retains some moisture. A quality indoor potting soil is sufficient, but adding perlite, coco coir, or bark improves aeration and drainage. These additions prevent compaction and waterlogging, which can harm the root system. An ideal pH is between 6 and 7.
Temperature and Humidity
Mandarin Spider Plants prefer moderate room temperatures, ideally 16-24°C (60-75°F). They adapt well to average household humidity. As they are native to subtropical and tropical regions, they appreciate higher humidity, and prolonged exposure to very dry air can cause brown leaf tips. To increase humidity, mist the plant occasionally or place it near a pebble tray filled with water, ensuring the pot is not submerged.
Fertilizing
During spring and summer, fertilize Mandarin Spider Plants every four to six weeks with a balanced liquid houseplant fertilizer diluted to half strength. Avoid over-fertilization, which can cause salt buildup, leading to brown leaf tips or burnt spots. Reduce or stop fertilizing during fall and winter when growth slows.
Propagating New Plants
Propagating Mandarin Spider Plants is a straightforward process. Unlike common spider plants, they do not produce “spiderettes” or “pups” on long stems. Instead, propagation is achieved through division or from seeds. For division, carefully remove the plant from its pot and gently separate the root ball into smaller sections, ensuring each has healthy roots and foliage. Plant each new section in its own pot with fresh potting mix.
Stem cuttings can also be rooted in water before transferring to soil. Change the water regularly. Once roots are a few inches long, plant the cutting into a small pot with moist, well-draining soil. Place the newly potted plant in a shaded, bright area with consistent moisture.
Addressing Common Care Problems
Mandarin Spider Plants are generally resilient, but issues can arise. Brown leaf tips often result from low humidity, mineral buildup from tap water, or over-fertilization. Using distilled or rainwater, or letting tap water sit overnight, can help. Increasing humidity also reduces browning.
Yellowing leaves indicate overwatering or underwatering. Overwatering causes root rot, while underwatering leads to dry, crunchy leaves. Adjust your watering schedule to allow the soil to dry between waterings. Though generally pest-resistant, occasional spider mites or mealybugs can occur and be treated with insecticidal soap.
Repotting Your Mandarin Spider Plant
Repotting is typically needed every one to two years, or when the plant is root-bound. Signs include roots growing from drainage holes, a top-heavy appearance, or stunted growth. Spring is an ideal time, as the plant enters its active growth phase.
When repotting, select a pot one size larger (e.g., 2 inches wider). Gently remove the plant, tease apart circling roots, and remove old soil. Add fresh, well-draining potting mix to the new pot, center the plant, and fill around the roots, maintaining the original depth. Water thoroughly after repotting.
Safety Considerations for Pets
The Mandarin Spider Plant (Chlorophytum orchidastrum ‘Mandarin’) is considered non-toxic to common household pets, including cats and dogs. The ASPCA lists spider plants as safe for pets. While ingestion of plant material may cause mild stomach upset or vomiting if consumed in large quantities, it is not poisonous. It is still advisable to monitor pets and prevent excessive chewing on any houseplant to avoid minor digestive disturbances.
