Pfeiffera monacantha (syn. Rhipsalis monacantha), the one‑spined wickerware cactus, is a species of epiphytic cactus, native to Bolivia and northwest Argentina. As its synonym Rhipsalis monacantha it has gained the Royal Horticultural Society's Award of Garden Merit.
Rhipsalis monacantha is fairly disease-resistant and tolerates normal care without becoming sick easily. That said, it can be vulnerable to mealybugs, which may cause some harm but are usually not a serious problem. In terms of care, Rhipsalis monacantha is drought-tolerant and does not require frequent watering. It can endure long periods without water and needs little fertilizer. However, if kept in poor light and overwatered, it is very prone to root rot. Overall, Rhipsalis monacantha is a good option for people who want low-maintenance plants, but it remains important to understand and meet its basic needs. It is particularly well-suited to those who are often away for long stretches and might forget to water regularly.
How to keep Rhipsalis Monacantha.
Light
Rhipsalis monacantha comes from habitats with dappled light — for example forest understories or rocky sites that offer natural shade. It prefers partial sun but is also able to tolerate full sun.
Temperature
Rhipsalis monacantha does best in warm surroundings and needs higher temperatures during the growing season to encourage growth and metabolic activity. It prefers plenty of sunlight, proper moisture levels, and good air circulation. However, it can be damaged by temperatures that are too low and by overwatering. Maintaining a balance is important, avoiding both excessively high heat and overly dry conditions.
Fertilizer
Rhipsalis monacantha only needs light fertilizer applications 1-2 times a year during the growing season. Do not fertilize in winter or summer when it is dormant. Cut back on fertilizer for repotted plants and wait a couple of months after repotting before applying any. Fertilizing helps maintain healthy growth and promotes flowering.
Pot & Repot
Repot Rhipsalis monacantha in spring or summer, selecting a pot slightly larger than the current one that offers good drainage. Use a well-draining, sandy or gritty cactus mix. Handle it carefully to avoid spikes. Let the cactus dry out before repotting to prevent root rot. After repotting, wait for a week before watering so the roots can heal.
