Caring for Dischidia nummularia, also known as the String of Nickels or Button Orchid Vine, is fairly straightforward. This plant is native to Southeast Asia and is known for its trailing growth habit and round, coin-like leaves. To ensure its health and growth, there are a few important factors to consider.
1. Light: Dischidia nummularia prefers shade to partial shade conditions. It can tolerate some direct sunlight, especially in the morning or late afternoon, but it’s best to avoid intense, direct sunlight as it can scorch the leaves. Providing bright, indirect light is usually ideal.
2. Temperature: This plant thrives in temperatures ranging from 45 to 95 degrees Fahrenheit (7 to 35 degrees Celsius). It can tolerate a wide range of temperatures, but extreme heat or cold should be avoided. Keep it away from drafts or sudden temperature fluctuations.
3. Watering: Allow the soil to dry out fairly between waterings. Overwatering can lead to root rot, so it’s important to strike a balance. Feel the top inch of soil, and if it feels dry, it’s time to water. Water thoroughly and ensure proper drainage to prevent waterlogged roots. During the winter months, reduce watering frequency as the plant enters a period of dormancy.
4. Humidity: Dischidia nummularia appreciates higher humidity levels, but it can adapt to average household humidity. You can increase humidity by misting the plant with water or placing it on a tray of moist pebbles. Avoid placing it near heaters or air conditioners, which can dry out the air.
5. Potting and soil: Use a well-draining soil mix that retains some moisture but allows excess water to flow out easily. A mix of peat moss, perlite, and orchid bark or coco coir works well. Repot the plant every 1-2 years or when it becomes root-bound. Choose a pot with drainage holes to prevent waterlogging.
6. Fertilizer: Feed Dischidia nummularia with a balanced, water-soluble fertilizer diluted to half strength during the growing season (spring and summer) every 2-4 weeks. Reduce or stop fertilizing during the winter months when the plant is dormant.
7. Pruning and propagation: Prune the plant to maintain its desired shape and size. You can trim back any leggy or overgrown stems to encourage bushier growth. Dischidia nummularia can be propagated through stem cuttings. Simply take a cutting with 2-3 nodes, remove the lower leaves, and place it in a moist soil mix or water until roots develop.
In my personal experience, Dischidia nummularia has been a relatively low-maintenance plant. I’ve found that providing it with bright, indirect light and allowing the soil to dry out before watering has worked well. Additionally, misting the plant occasionally during dry periods has helped maintain sufficient humidity levels. Regular pruning has helped keep the plant compact and attractive. with the right care, Dischidia nummularia can be a beautiful addition to any indoor or outdoor space.
