Among the plethora of cacti, one stands out not just for its resilience but also for its distinctive leaf pattern: the Fishbone Cactus. Officially known as Epiphyllum anguliger, this cactus carries the casual names of “Fishbone Cactus” or “Ric Rac Orchid Cactus” due to its leaves that zigzag like the bones of a fish or the teeth of a saw. Originating from the rainforests of Mexico, this cactus is a visual delight and a favorite among plant enthusiasts.

What differentiates the Fishbone Cactus from most of its desert relatives is its natural habitat. Instead of the arid terrains commonly associated with cacti, it hails from rainforests thriving as an epiphyte. Epiphytes grow on the surface of other plants, typically trees, drawing nutrients from the air, rain, and the debris around them. They are not parasitic; instead, they simply use other plants as a support. This natural predisposition makes the Fishbone Cactus an excellent candidate for hanging baskets where its long, serrated leaves can drape down gracefully.

A hallmark of the Fishbone Cactus is its adaptability to indoor settings. It prefers bright, indirect light, making east or west-facing windows ideal homes. While it avoids the scorching midday sun, it also does not like to be in deep shade. The balance ensures the leaves retain their deep green hue and continue the characteristic zigzag growth.

Watering is crucial. The Fishbone Cactus is more forgiving than its desert counterparts when it comes to moisture but it detests waterlogged roots. The soil, typically a mix designed for cacti with added perlite or orchid bark, should be well-draining. A good rule of thumb is to allow the top inch of soil to dry out between waterings. Overly damp conditions can pave the way for root rot, an ailment many indoor plants fall victim to.

However, while the soil should not be perpetually wet, the ambient air can be. Native to humid rainforests, the Fishbone Cactus flourishes in higher humidity levels. This makes it suitable for areas like kitchens or bathrooms where humidity is naturally higher. But fret not if you’re placing it elsewhere; a simple tray with water and pebbles or occasional misting can suffice.

Beyond its daily care, what’s truly enchanting about the Fishbone Cactus are its flowers. They are nocturnal, blooming at night, and exude a pleasant fragrance. While the blooms are short-lived, usually lasting just a night, their appearance is a spectacle, adding another layer of appeal to this already fascinating plant.

In conclusion, the Fishbone Cactus, with its unparalleled leaf design and care accessibility, offers plant lovers a taste of the tropics right in their homes. Whether you’re a novice gardener or a seasoned botanist, this cactus ensures a blend of aesthetic appeal and horticultural satisfaction.

Fishbone Cactus Care

The Fishbone Cactus, also known as Epiphyllum anguliger or Ric Rac Orchid Cactus, is known for its unique zig-zag or “fishbone” patterned leaves. Native to the forests of Mexico, it’s an epiphytic cactus, meaning it naturally grows on trees rather than in soil. Here’s a guide on how to care for and grow a Fishbone Cactus:

1. Light

Fishbone Cactus (Epiphyllum anguliger) has distinct light requirements that differentiate it from many desert cacti. Native to the understory of Mexican rainforests, it’s accustomed to dappled sunlight filtered through dense canopy layers. As an indoor plant, it thrives in bright, indirect light. East or west-facing windows are ideal providing gentle morning or late afternoon sun. Direct midday sunlight can scorch its delicate leaves, so, shielding it during these hours is crucial. If light is too low, the cactus may become leggy as it stretches for light. Ensuring the right light balance promotes healthy growth and encourages the production of its enchanting nocturnal blooms.

2. Water

Watering is pivotal to the Fishbone Cactus’s health. Native to the Mexican rainforests, this epiphytic cactus, unlike its desert relatives, appreciates a bit more moisture. However, it detests waterlogged conditions. A well-drained soil mix ensures its roots are not submerged in water. The golden rule is to let the top inch of soil dry out between watering sessions. Over-watering can lead to root rot, a common ailment for houseplants. During its growing season, the Fishbone Cactus prefers consistent moisture. Conversely, in its dormant period, reduce watering frequency. Always use pots with drainage holes and avoid letting the cactus sit in stagnant water.

3. Soil

The Fishbone Cactus, native to the rainforests of Mexico, thrives in a distinctive soil blend that mirrors its epiphytic roots. Unlike typical desert cacti, this unique plant naturally grows on tree surfaces, absorbing nutrients from organic debris. Hence, its ideal soil mix is both well-draining and rich in organic matter. A blend of cactus potting mix with orchid bark or coconut coir offers the perfect balance. Perlite is often added to improve aeration and drainage, ensuring the roots receive ample oxygen without remaining soggy. Regularly checking the soil’s consistency and adjusting as needed ensures this tropical marvel flourishes indoors.

4. Humidity

The Fishbone Cactus, hailing from the tropical rainforests of Mexico, has an inherent affinity for humidity. Unlike desert-dwelling cacti, this epiphytic plant naturally thrives in environments where moist air envelops its zig-zag leaves. Humidity supports its growth, ensures leaf vigor, and aids in the successful unfurling of its nocturnal blooms. When cultivating Fishbone Cactus indoors, it benefits from higher humidity levels often found in kitchens or bathrooms. In drier climates or during winter months, using a humidity tray or occasional misting can help emulate its tropical habitat. Regularly monitoring ambient moisture ensures this captivating cactus remains in optimal health.

5. Fertilizing

Fishbone Cactus (Epiphyllum anguliger), like many plants, benefits from periodic fertilization to support its growth and blooming. For these tropical epiphytes, a balanced, water-soluble fertilizer, typically a 20-20-20 mix, works best. Fertilizing should be done during the active growing season, generally from spring through early fall, once a month. To avoid over-fertilizing, it’s wise to dilute the fertilizer to half the recommended strength. Applying fertilizer ensures the cactus receives essential nutrients that might be lacking in its potting mix, promoting vibrant growth and, eventually, those enchanting nocturnal blooms. Always water thoroughly after fertilizing to distribute nutrients evenly.

6. Pruning

Pruning the Fishbone Cactus (Epiphyllum anguliger) can be essential for maintaining its health and aesthetic appeal. Over time, this epiphytic cactus can produce elongated stems that may appear unruly or unattractive. Pruning allows you to manage its shape, remove any dead or damaged stems, and encourage more vigorous growth. When pruning, use sterilized scissors or pruning shears to prevent the introduction of diseases. Gently cut the stems back, preferably close to a branching point. These cuttings can be propagated if desired. Ideally, prune during the growing season to allow the plant to heal faster and minimize stress.

7. Propagation

Propagation of the Fishbone Cactus (Epiphyllum anguliger) is a rewarding endeavor that allows enthusiasts to multiply this unique plant. Typically done through stem cuttings, the process starts by selecting a healthy, mature segment. After making a clean cut, it’s crucial to let the segment callus or dry for a few days, minimizing the risk of rot when planted. Using a well-drained soil mix, the callused end is then planted and the cutting is left undisturbed to establish roots. Given proper care, which includes indirect light and regulated watering, the cutting soon develops into a thriving new Fishbone Cactus.

8. Pests

Fishbone Cactus, while being resilient, isn’t entirely immune to pests. The most common invaders are mealybugs and spider mites. Mealybugs appear as tiny, white, cottony masses on the cactus, often hiding in leaf axils or under the leaves. They suck the plant’s sap, weakening it and potentially introducing diseases. Spider mites are tinier, almost microscopic, but their presence is hinted at by fine webs on the plant and a silvery or stippled appearance of the leaves. Both pests thrive in dry, warm conditions. Combatting them involves increasing humidity, regularly inspecting the plant, and, if needed, using insecticidal soap or neem oil treatments.

9. Temperature

The Fishbone Cactus (Epiphyllum anguliger) originates from the tropical rainforests of Mexico, influencing its temperature preferences. Unlike many desert cacti, it favors a more moderate temperature range. Ideally, it thrives in temperatures between 50-75°F (10-24°C). While it can tolerate slight drops during its dormant winter period, it’s sensitive to prolonged cold and frost. Exposure to temperatures below 50°F can harm the plant. On the warmer side, while the cactus can handle temporary spikes in heat, prolonged exposure to very high temperatures can stress the plant causing it to wilt or even scorch. For optimal growth, maintaining consistent, moderate temperatures and avoiding extremes is essential for Fishbone Cactus.

6. Wait to Water

  • After planting the cutting, wait for a week before watering. This gives the cutting some time to adjust and root slightly before being exposed to moisture.

7. Watering and Care

  • Once you begin watering, ensure the soil is thoroughly moistened, but make sure it dries out between watering sessions. Over-watering can lead to rot.
  • Place the pot in a location with bright, indirect light.

8. Root Development

  • The cutting will develop roots in a few weeks. You can check for root development by giving the cutting a gentle tug. If it resists, it’s likely rooted.
  • However, be patient; sometimes, it might take longer than expected.

9. Transplanting (if necessary)

  • Once the cutting has established a good root system and starts growing, you can choose to transplant it to a bigger pot or its final location.

10. Watch for Growth

  • With proper care, the propagated Fishbone Cactus will start growing and, over time, will become a mature plant that may produce its iconic nocturnal flowers.

Propagation not only allows you to multiply your collection but is also an enjoyable process for gardening enthusiasts. Always remember to use clean tools to minimize the risk of infections.

Potting and Repotting Fishbone Cactus

Potting and repotting the Fishbone Cactus (Epiphyllum anguliger) are vital processes to ensure its healthy growth. Here’s a comprehensive guide to help you understand and perform these tasks efficiently:

Potting Fishbone Cactus

  • Choose the Right Pot: Start with a pot that’s slightly bigger than the root ball of the cactus. Ensure the pot has good drainage holes to prevent waterlogged conditions.
  • Soil Mix: Fishbone Cactus thrives in a well-drained soil mix. Use a commercial cactus or succulent potting mix. To enhance drainage, you can add some perlite, orchid bark, or coarse sand.
  • Planting: Fill the pot with the prepared soil mix until it’s about a third full. Position the cactus so its roots spread out evenly. Add more soil, pressing it down gently, until the cactus is anchored securely. Leave some space at the top for watering.
  • Initial Watering: Water the newly potted cactus thoroughly, ensuring the soil is well-moistened. This helps to settle the soil around the roots.

Repotting Fishbone Cactus

1. When to Repot: Repotting becomes necessary when the cactus outgrows its current pot or the soil becomes exhausted. Generally, every 2-3 years is a good interval. Signs that your cactus needs repotting include:

  • Roots growing out of the drainage holes
  • Soil drying out faster than usual
  • Visible reduction in growth rate

2. Removing the Cactus: Gently ease the cactus out of its current pot. If it’s stuck, you can tap the pot’s sides or bottom to loosen the root ball.

3. Inspect the Roots: Before repotting, check the root system. Trim off any rotten or overly long roots. Healthy roots should be firm and white or tan.

4. Choose a Slightly Larger Pot: The new pot should be slightly larger than the previous one, ensuring room for growth. Remember, drainage is essential, so ensure the pot has drainage holes.

5. Repotting Process: The process is similar to the initial potting. Fill the pot with a third of the soil mix, position the cactus, and then add more soil, pressing gently.

6. Watering After Repotting: Allow the cactus to settle for about a week before you water it. This waiting period helps any disturbed or cut roots to heal, reducing the risk of rot when watered.

After either potting or repotting, place the Fishbone Cactus in its preferred location with bright, indirect light. Maintain regular care, ensuring the soil remains well-draining and not overly wet.

As with all repotting, the key is to be gentle and ensure that the plant experiences as little stress as possible during the transition.

Soil Mix for Fishbone Cactus
