WaterThe Nelson's fishbone cactus should be watered thoroughly, allowing the water to run through the drainage holes, indicating that the soil is fully saturated. In the growing season, from spring to fall, water when the top inch of soil feels dry, which may be approximately once a week, but always check the soil moisture level first. During winter, reduce watering to once every three to four weeks as the plant enters a dormancy period. The amount of water needed will vary with the size of the pot but expect to use about 8 to 16 ounces of water for small pots or up to 1/2 gallon for larger pots each time you water. It is crucial to avoid letting the plant sit in water as it can lead to root rot.
LightThe Nelson's fishbone cactus prefers bright, indirect sunlight. It thrives when placed in a well-lit room, near a window where it can receive natural light but is shielded from direct rays of the sun, especially during the harsh midday period. An east or north-facing window would be ideal, providing gentle morning sunlight without the risk of scorching the foliage.
TemperatureThe Nelson's fishbone cactus does best in temperatures ranging from 60 to 75 degrees Fahrenheit and can survive minimum temperatures of 50 degrees Fahrenheit. Avoid exposing the plant to temperatures below 50 degrees for prolonged periods as it can damage the plant. The cactus will appreciate being kept in a consistent temperature range and protected from drafts and extreme temperature fluctuations.
PruningPruning of the Nelson's fishbone cactus is done to maintain its shape, remove any dead or damaged stems, and encourage fuller growth. It is best to prune at the beginning of the growing season, typically in early spring. Use clean, sharp utensils to make cuts, and only prune as needed to shape the plant or remove unwanted sections. Over-pruning is not necessary and can be detrimental to the plant's health.
CleaningAs needed

Life cycleThe life of a Nelson's Orchid Cactus (Disocactus nelsonii) begins with seed germination, which occurs best in a humid and warm environment. Once germinated, the seedlings slowly develop into young plants with characteristic elongated stems. As the plant matures, it develops segmented stems and areoles from which spines emerge. It reaches reproductive maturity after a few years and produces showy, funnel-shaped flowers that are typically white or pink, usually in the spring or early summer. After pollination, possibly involving hummingbirds or insects, the flowers develop into small, berry-like fruits containing seeds, which can be dispersed to give life to new plants. Over many years, the plant can reach a considerable size and might need support or pruning to manage its form, and it typically continues to grow and reproduce cyclically each year.

Spring-Early Summer
The most popular method for propagating the Orchid Cactus (Disocactus nelsonii) involves taking stem cuttings. Typically, the best time to do this is in the late spring or early summer when the plant is actively growing. Cuttings should be made from healthy, mature stems, taking sections about 4 to 6 inches (10 to 15 centimeters) long. After cutting, allow the ends to callous over by setting them aside in a dry, shaded area for a few days. Once calloused, the cuttings can be planted in a well-draining potting mix, about 1 inch (2.54 centimeters) deep. To stimulate root growth, it's crucial to maintain a humid environment and a steady temperature of about 70°F (21°C). Roots usually develop within a few weeks, after which the plant can continue to grow under normal care conditions.
