Rhipsalis is a genus of cacti with approximately 35 distinct species. One of the most popular species is Rhipsalis baccifera, commonly known as the Mistletoe Cactus.
While many people think of prickly plants native to American deserts when they hear the name "cactus," most Rhipsalis have no spines and would not survive the dry soil and bright sun of a desert. All species are native to the rainforests of South America, the Caribbean, and Central America, which has led to their classification as jungle cacti. Because jungle cacti and desert cacti come from different native environments, caring for Rhipsalis means setting aside any preconceived notions about what cacti prefer.
Lighting Requirements
Rhipsalis cacti do not thrive in direct sunlight. Afternoon sun can burn the stems, turn them yellow, or cause spotting. However, they will not bloom without sufficient sunlight, and their growth can be stunted. These cacti do best with morning sun and full shade in the afternoon. Because Rhipsalis cacti are commonly grown indoors, take care with their placement. Keep them at least 20 inches (50 cm) from windows that receive midday or afternoon sun. Window glass can intensify the sun's heat, causing sunburned leaves. Keep in mind that in its native environment, Rhipsalis is accustomed to receiving light filtered through dense, overhanging tree branches. Picturing this environment can help you adjust your lighting accordingly.
Watering
Rhipsalis cacti are not drought-resistant plants, so regular watering is essential. Overwatering, however, can weaken stems and rot roots. Using a watering can helps you measure how much water you are providing. Pot size relative to the plant, the home's humidity levels, and the type of potting soil used can all affect watering frequency. Rhipsalis cacti rarely need watering more than once a week. Before watering, press your finger into the soil to a depth of half an inch. Postpone watering if the soil is moist. You can also use a moisture meter to help you decide when to water.
Selecting Pots
Rhipsalis cacti do best when planted in clay pots. Clay pots let the soil "breathe" better than other types, helping dissipate moisture that could rot the plant's roots. Most species produce long, hanging leaves that make them ideal hanging plants, so many people choose pot styles that fit a metal or macramé plant hanger.
Soil
Novices in the world of jungle cacti might prefer to purchase potting soil specifically for cacti. However, experienced succulent growers can make their own by combining regular potting soil with coir, orchid bark, or gravel to ensure proper drainage. Most species need to be transplanted using fresh potting soil every two or three years. When repotting, take care not to damage the roots.
Fertilizing
Do not feed newly repotted or just purchased Rhipsalis for 12 months. Rhipsalis cacti do not need feeding until the soil becomes depleted of nutrients. If you want to feed it, use a diluted, half-strength cactus fertilizer. Feed monthly only during spring and summer. Follow the fertilizer directions to determine the correct quantity, which depends on plant size, pot size, and other factors.
