Learn More about Epiphyllum anguliger
Epiphyllum anguliger is an exotic, epiphytic plant originating from Mexico, showcasing distinct angular foliage.
Epiphyllum anguliger, also known as Disocactus anguliger, shares genetic ties with the Disocactus genus, evident from its name deriving from the remarkable angular leaf patterns it bears.
Commonly referred to as the fishbone cactus or zig-zag cactus due to its leaf shape, this plant may also be mistakenly labeled as ric rac cactus or orchid cactus. However, distinguishing features, like thicker leaves at the center compared to Cryptocereus anthonyanus, help tell these species apart.
Despite its appearance, Epiphyllum anguliger belongs to the Cactaceae family, differing in its epiphytic behavior while resembling other familiar cacti structurally.
Native Habitat
Fishbone cactus uses aerial roots to gather nutrients from tree debris.
Hailing from the jungles of Mexico, fishbone cacti thrive as epiphytes, clinging to trees for sunlight and moisture. Their aerial roots absorb moisture from the air and gather nutrients from tree crevices.
Contrary to the desert environment associated with cacti, fishbone cacti prefer tropical conditions, making them ideal indoor companions due to their low maintenance requirements and shared light and humidity preferences with many houseplants.
Distinct Attributes
These epiphytes prefer bright, indirect light to thrive.
Most cactuses require direct sunlight for optimal growth, but the fishbone cactus is different. These epiphytes typically grow under tree canopies, receiving filtered sunlight. Indoors, they thrive with bright indirect sunlight, ideally near east, south, or west-facing windows. Direct sun in the morning is fine, but avoid intense noon sunlight to prevent leaf burns.
While they like light, fishbone cactuses can’t thrive in low-light areas either. Ensure they get bright indirect light for most of the day and some gentle direct sun for an hour or two to promote flowering and fruiting.
Water
Check the soil every few days and water when the top half of the soil has dried out completely.
Proper watering is crucial for your fishbone cactus. Unlike desert cactuses, this plant needs some water but can’t handle overwatering. Its roots are prone to rot if watered excessively. Allow the top half of the soil to dry out before watering to maintain the balance between moisture and aeration.
Avoiding overwatering is crucial for the health of the fishbone cactus. Rather than rushing to water it, it’s important to give the plant time to dry out, as excess moisture can be detrimental.
Attempting to stick to a strict watering schedule for your fishbone cactus may lead to issues with under or overwatering. Factors like environmental conditions can vary daily and affect the soil’s moisture levels, making a set schedule unreliable.
For optimal care, it is recommended to regularly check the soil moisture and only water when the top half of the soil has completely dried out. This approach ensures a balance between hydration and proper aeration for the plant.
Soil
Fishbone cactuses thrive in loose, well-draining soil that doesn’t retain excess water.
Proper soil composition is essential for fishbone cactuses to support their epiphytic roots. Similar to orchids, these plants require a soil mix that offers stability to the roots while preventing waterlogging.
While there’s no immediate need to repot a newly bought fishbone cactus, keep in mind that it will eventually require repotting as it outgrows its current container or the soil quality deteriorates over time.
Ordinary potting soil is not suitable for fishbone cactuses. To mimic their natural habitat conditions, opt for a well-draining mix like orchid or succulent mix amended with coconut coir, bark chips, and perlite.
To maintain consistency with the soil texture, refer to the original potting mix of the cactus and match it as closely as possible to ensure the plant’s well-being and minimize stress.
Temperature and Humidity
Epiphyllum anguliger thrives in temperatures above 65F.
With a preference for warm temperatures, Epiphyllum anguliger enjoys indoor temperatures above 65F to sustain optimal growth throughout the year.
While they can tolerate slightly lower temperatures, growth may slow or cease until warmer conditions return. Avoid exposing them to temperatures below 50F to prevent potential damage.
Unlike desert cactuses, fishbone cactuses require higher humidity levels to thrive. Maintaining around 60% humidity is ideal, but levels above 40% are generally suitable for their well-being.
If your indoor environment lacks humidity, consider using methods like misting or placing the plant in a naturally more humid location to create a favorable setting for the plant.
Fertilizing
Fertilize your fishbone cactus with a liquid fertilizer in the early spring.
While fishbone cactuses are not heavy feeders, a well-timed nutrient boost is essential if your plant shows signs of nutrient deficiency after being in the same container for an extended period.
Ensuring the right nutrient levels are crucial for promoting the blooming and fruiting of your fishbone cactus. When it comes to fertilizing, a single application in early spring using a liquid fertilizer tailored for cactuses is typically adequate. Only consider administering a half-strength dose in the summer if your plant shows signs of struggle. Be cautious not to overfertilize, as fishbone cactuses are accustomed to low nutrient levels in their natural environments and can be sensitive to excessive fertilization. Opt for minimal fertilization or consider repotting with a fresh, nutrient-rich soil mix to maintain optimal root health.
Propagation of fishbone cactus is a simple yet rewarding process that involves using cuttings. Whether you are eyeing a larger collection of these plants or wish to salvage cuttings from pruning, propagating can be done throughout the year, with early spring being the preferred time. Cutting segments about 4 to 5 inches long and allowing them to dry before planting is key to successful propagation. These cuttings can then be placed in a well-draining mixture of coconut coir and perlite or river sand to encourage root development.
To ensure healthy growth, your fishbone cactus may require repotting every 2 to 3 years, especially for younger plants. Signs that it’s time for repotting include roots protruding from drainage holes and rapid soil drainage. When repotting, handle the plant carefully to avoid damaging its delicate roots and consider using a container only slightly larger than the current one. After repotting, refrain from immediate watering to minimize shock and aid in the plant’s recovery from root disturbance.
Common issues that may arise with fishbone cactuses include scale infestations, which can be identified by brownish waxy shells on the leaves. Regularly inspect your plant for pests and address any infestations promptly to maintain its health and vitality. With proper care and attention to these key aspects of growth and maintenance, your fishbone cactus can thrive and provide you with the joy of a flourishing indoor garden.
Problems can arise with fishbone cacti.
Easy Care: Understanding the needs of fishbone cacti makes caring for them a breeze. Compared to other houseplants, they require minimal attention. Common growth issues stem from misconceptions about their care.
Lighting: Despite being cacti, fishbone cacti should not be exposed to full sun all day. Excessive direct sunlight can result in brown spots on the leaves and a withered appearance. Indirect sunlight for most of the day with brief periods of gentle direct sunlight is ideal.
Watering: Overwatering is a common struggle for plant owners, but underwatering is more likely to affect fishbone cacti. Despite being cacti, Epiphyllum anguliger requires more water than desert cacti. Inadequate watering can cause thin leaves and stunted growth.
Environmental Concerns: Placing the plant in an unsuitable environment or pot can lead to issues like browning leaf tips due to low humidity or yellowing lower leaves from overwatering. While pests and diseases like scale and mealybugs are possible, they are not prevalent in fishbone cacti.
Preventive Care: Regularly monitor your plant for signs of stress and provide optimal care and conditions. Mimicking their native environments enhances the plant’s health and appearance.
