Rhipsalis capilliformis, commonly known as the Mistletoe Cactus or Dancing Bones Cactus, is a distinctive cactus from the rainforests of Central and South America. Unlike its desert relatives, this naturally epiphytic plant grows on other trees or rocks rather than in soil. It is characterized by long, delicate, trailing stems resembling fine threads, making it popular for hanging baskets and indoor displays. Its adaptability and low maintenance make it a popular houseplant.
Rhipsalis Capilliformis Care Essentials
Light Needs
Rhipsalis capilliformis thrives in bright, indirect light, mimicking its natural environment. Placing it near a north-facing window or in a spot with filtered sunlight is ideal. Direct, harsh midday or afternoon sun can scorch its delicate stems, causing a red tinge. Pale or stunted growth indicates insufficient light, suggesting a need for more light.
Watering Practices
Despite being a cactus, Rhipsalis capilliformis requires more consistent moisture than desert cacti due to its rainforest origins. Allow the top inch or two of soil to dry out between waterings. Overwatering is a common issue that can lead to root rot, so avoid constantly saturated soil. Watering frequency varies with seasons and humidity; less is needed in winter. Dehydration signs include drooping or puckered tendrils.
Ideal Soil Mix
A well-draining and airy soil mix is essential for Rhipsalis capilliformis. A suitable blend includes orchid bark, perlite, and a peat-based or coco coir potting mix. A general cactus compost often works well, or a mix of approximately 60% houseplant potting mix with 40% perlite provides aeration and drainage. This prevents waterlogging, detrimental to plant health.
Temperature and Humidity
Rhipsalis capilliformis prefers warm, tropical temperatures, above 50°F (10°C), and is not frost-tolerant. While it tolerates average room humidity, it appreciates higher levels, especially indoors with dry air. Misting regularly or placing it on a pebble tray increases humidity. Consistent humidity supports healthy growth.
Fertilizing Schedule
Rhipsalis capilliformis are not heavy feeders, but they benefit from light fertilization during active growth. Apply a diluted, balanced liquid houseplant fertilizer monthly during spring and summer. Avoid fertilizing during winter dormancy to avoid stress. A 1-2-2 NPK fertilizer is suitable, applied quarterly.
Repotting Your Rhipsalis Capilliformis
Repotting Rhipsalis capilliformis is typically needed every two to three years, or when roots fill the pot. Spring is the best time for repotting, as rising temperatures and daylight stimulate new growth. Choose a pot only slightly larger than the previous one, as a larger pot can lead to excess moisture and root issues. Ensure the new pot has drainage holes for drainage.
To repot, gently remove the plant and loosen compacted soil around the roots. Fill the new pot about one-third with a fresh, appropriate soil mix, then center the plant and fill the remaining space, gently firming the soil. Water the plant thoroughly after repotting to help it settle. Avoid fertilizing for about six weeks after repotting to allow roots to adjust.
Propagating Rhipsalis Capilliformis
Propagating Rhipsalis capilliformis is best achieved through stem cuttings. Take cuttings during active growth in spring and summer. To prepare, select healthy stems and snip 3 to 6-inch segments using sterilized scissors or pruners. Allow ends to air dry and callus for a few days after cutting; this prevents rot when placed in soil or water.
Root cuttings directly in a well-draining potting mix or in water. If planting in soil, insert the calloused end 0.5 to 0.75 inches deep, gently patting soil around it. Keep the soil lightly moist but not saturated. For water propagation, place the snipped end in a clean glass of water, ensuring at least one node is submerged. Roots typically form within one to two weeks; transfer to soil once a few inches long.
Troubleshooting Common Rhipsalis Capilliformis Issues
Several issues can arise with Rhipsalis capilliformis, often indicating care imbalances. Yellowing and softening stems, especially at the base, can signal overwatering and root rot. If this occurs, inspect roots for brown, mushy sections and allow soil to dry more thoroughly between waterings. Conversely, shriveled or dry stems indicate underwatering; the plant typically revives once hydrated.
A reddish tinge on the stems often signals too much direct sunlight, requiring a move to brighter, indirect light. Stunted or slow growth, along with pale leaves, suggest insufficient light or nutrient deficiency. Adjusting its position for more indirect light or introducing light fertilizer during the growing season can help. Regular observation helps in early diagnosis and correction.
