How to Grow and Care for String of Nickels

The string of nickels (Dischidia nummularia) is a type of succulent vine native to the tropical regions of Asia, India, and Australia. It is a type of epiphyte similar to orchids and aerial plants, such as Tillandsia, which means that in its native habitat, the nickel cord grows on other plants, such as trees, and gets its moisture and nutrients from the air, rain, or debris. that accumulate around you, rather than on the ground.

This Dischidia is a relatively unusual houseplant that can be difficult to find, but if you can get one, it will look good almost anywhere in your home. Unlike many other types of succulents, the coin row does not require a clear, sunny location; in fact, it prefers low light conditions.

String of Nickels Care

These tropical epiphytes generally require little maintenance and are easy to care for. They are most commonly grown indoors as houseplants, as they cannot tolerate cold or frosty temperatures, but can be grown outdoors year-round in consistently warm climates. They enjoy constant humidity and are prolific growers in the right environment.

Recommended to be replanted annually so they don't stick to the root, which can stunt growth, as your roots need enough aeration to thrive. String of nickels do not require pruning, but since they can grow quickly, they can be trimmed and shaped as needed.


String of nickels grows well in low light conditions. Indoors, are the perfect choice for that low light north or east-facing window. Ideally, they should receive some sunlight throughout the day; a small amount of morning or afternoon sun is perfect.

When grown outdoors, a row of coins should be grown in shady locations, protected from the afternoon sun. They do well in baskets or vases that hang under covered balconies or patios.


String of nickels wires should be grown in a light and airy environment, well-drained, and with a high content of organic matter. As epiphytes, their roots require airflow to thrive.

A potting mix of orchid, shredded coconut, or shredded bark is a good choice for coin strings. Do not plant a nickel wire in normal potting soil, as it is very dense and the roots will suffocate and rot.


Keep the potting medium evenly moist, but be careful to avoid soaking the roots; they should never be sitting in water for long periods of time. Nickel wires also benefit from regular fogging, which helps the plant absorb moisture through the leaves.

Temperature and humidity

String of nickels thrive in hot and humid environments and cannot tolerate cold or icy temperatures. They are hardy in USDA zones 9 through 11 but are typically grown indoors as houseplants. While a series of coins work well in the average humidity of a home, if you put it in a place with some additional humidity, like a kitchen or bathroom, it will work well.


String of nickels does not require regular fertilization beyond ensuring that your growing medium is rich in organic matter. However, if desired, a low resistance balanced fertilizer can be applied annually at the beginning of the growing season.

Are String of Nickels Toxic?

These tropical epiphytes are not toxic to pets or humans; however, the sap can be mildly irritating if it comes into contact with the skin. Take care when planting or transplanting a series of coins with gardening gloves to avoid skin irritation.

Symptoms of Poisoning

    • Skin irritation

    Propagating String of Nickels

    String of nickels are easily propagated by stem cuttings. Take the seedlings of a healthy, established plant and let the stems sit numb for a few hours before they take root in the damp sphagnum moss.

    It usually takes a few weeks for the roots to settle. Once the cuttings are well rooted, they can be moved to a regular organic growing medium and cared for like a mature nickel cord.

    Common Pests and Diseases

    Root rot is the most common disease affecting various coins. To prevent the roots from rotting, make sure the nickel cord is not overwatered and that the growing medium allows air to reach the roots.

    Nickel wires can also be susceptible to some common pests like spider mites, mosquito fungi, aphids, and scale insects. Be sure to regularly inspect your nickel chain for pests so that you can spot any infestation as soon as possible.
