The String of Nickels (Dischidia nummularia) is a trailing houseplant known for its small, coin-shaped leaves that cascade gracefully. Its unique appearance makes it a great addition to any indoor space, especially in hanging baskets or on shelves. Native to tropical regions of Asia and Australia, this epiphyte naturally grows on trees. Its low maintenance requirements make it suitable for both novice and experienced plant enthusiasts.
Essential Care Requirements
Light
The String of Nickels thrives in bright, indirect light, mimicking its natural habitat under a tree canopy. Place it near an east or north-facing window for gentle morning light. If near a south or west-facing window, use a sheer curtain to filter intense afternoon sun, which can scorch leaves and cause brown or crispy edges. Insufficient light leads to smaller leaves and leggy stems as the plant stretches.
Watering
Proper watering is important for the String of Nickels to prevent issues. The plant prefers its soil to dry out between waterings; allow the top inch or two of the potting mix to become dry before rewatering. Overwatering causes problems like root rot, as the plant is sensitive to consistently wet conditions. Conversely, underwatering can cause leaves to shrivel or become crispy. Adjust watering frequency seasonally, needing less water during cooler fall and winter months when growth slows.
Soil
The soil mix for String of Nickels should be well-draining, airy, and slightly acidic, reflecting its epiphytic nature. A suitable blend includes components like orchid bark or coco husk chips, mixed with perlite or pumice for drainage and aeration. Some growers also incorporate a small amount of peat moss or coco coir to retain moisture. Avoid standard potting soil, as it holds too much water and can become compacted, harming the plant’s root health.
Temperature and Humidity
String of Nickels prefers warm temperatures, between 65°F and 80°F (18°C to 27°C). It is sensitive to cold drafts and temperatures below 50°F (10°C), which can stress the plant. As a tropical plant, it benefits from moderate to high humidity. To increase humidity indoors, place the plant on a pebble tray filled with water, use a room humidifier, or group it with other humidity-loving plants.
Fertilizing
Light fertilization supports healthy growth during the active growing season (spring and summer). Apply a balanced liquid fertilizer, diluted to half strength, once a month. Over-fertilization can harm the plant, so it is better to under-fertilize. During fall and winter, when growth slows, reduce or stop feeding.
Repotting Your String of Nickels
Repotting String of Nickels is needed every two to three years, or when the plant becomes root-bound with roots emerging from drainage holes. Spring is the preferred time for repotting, aligning with the plant’s natural growth spurt. Choose a new container only slightly larger than the current pot, or similar in size to maintain current dimensions. Terracotta pots are beneficial due to their porous nature, promoting better drainage and air circulation around the roots. The repotting process should be gentle to avoid damaging roots.
Propagating String of Nickels
Propagating String of Nickels is achieved through stem cuttings. Select a healthy vine segment with at least two to four nodes (points where leaves attach). Remove leaves from the lower half of the cutting to expose these nodes.
Cuttings can be rooted in water or directly in a well-draining soil mix. If rooting in water, change the water every few days. If planting directly into soil, ensure at least two nodes are buried. Warmth, indirect light, and consistent humidity encourage successful root development, which takes a few weeks.
Troubleshooting Common Issues
Yellowing leaves on a String of Nickels indicate overwatering or inadequate drainage. Ensure the soil dries out between waterings and the pot has proper drainage to resolve this. Conversely, shriveling or crispy leaves point to underwatering or low humidity. Increasing watering frequency or boosting ambient humidity can alleviate these symptoms.
Lack of robust growth or a sparse appearance can result from insufficient light or a nutrient deficiency. Move the plant to a brighter location with indirect light and apply diluted fertilizer during the growing season to stimulate healthier growth. Common houseplant pests like mealybugs, spider mites, and scale insects can affect String of Nickels. Regularly inspect the plant and treat infestations with insecticidal soap or neem oil to manage these issues.
