Everything it needs
9 essentials at a glance
Watering
Rhipsalis pilocarpa prefers to be watered when the top inch of soil feels dry.
During the growing season (spring and summer), water every 2-3 weeks, allowing excess water to drain. In fall and winter, reduce watering to once a month. Signs of over-watering include yellowing stems and mushy texture, while under-watering may cause shriveling and wilting.
Light
This plant thrives in bright, indirect light but can tolerate partial shade.
Ideally, place it near a window with filtered sunlight for about 6-8 hours a day. Avoid direct sunlight, as it can scorch the stems.
Soil
Rhipsalis pilocarpa prefers a well-draining potting mix, ideally a cactus mix or a blend of potting soil, sand, and perlite.
The pH should be slightly acidic to neutral, around 6.0 to 7.0. Ensure the pot has drainage holes to prevent water retention.
Humidity
This plant enjoys moderate to high humidity levels, ideally between 40-60%.
To increase humidity, mist the plant regularly or place it on a pebble tray filled with water. Signs of low humidity include browning leaf edges and stunted growth.
Temperature
Rhipsalis pilocarpa thrives in temperatures between 65-80°F (18-27°C).
It is not frost-tolerant and should be kept above 50°F (10°C). This plant can tolerate temperatures up to 90°F (32°C) but may need additional humidity in extreme heat.
Fertilizing
Use a balanced, diluted liquid fertilizer with an NPK ratio of 10-10-10 during the growing season, every 4-6 weeks.
In fall and winter, refrain from fertilizing. Signs of nutrient deficiency include yellowing stems and poor growth.
Pruning
Prune Rhipsalis pilocarpa in spring to remove any dead or damaged stems.
Use clean, sharp scissors or pruning shears. Light shaping can be done to maintain a bushy appearance, and deadheading is not necessary as it does not produce showy flowers.
Repotting
Repot Rhipsalis pilocarpa every 2-3 years or when it outgrows its pot.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Carefully remove the plant from its pot, refresh the soil, and place it in the new pot.
Propagation
Propagation can be done through stem cuttings.
Take a healthy stem segment, let it dry for a day to form a callus, then plant it in a well-draining potting mix. Water lightly and keep in a warm, humid environment. Best timing for propagation is during the spring.
