How to Grow and Care for Selenicereus anthonyanus “Ric-Rac” Cactus
Growing and caring for the Ric-Rac cactus can be a rewarding experience. With its tropical origins, this plant has specific needs that differ from those of desert cacti. Follow these guidelines to help your Selenicereus anthonyanus thrive and become a stunning centerpiece in your plant collection.
1. Light Requirements
The Ric-Rac cactus prefers bright, indirect light. In its native habitat, it grows under the canopy of trees, where it is shielded from direct sunlight. Too much direct sunlight can scorch its delicate stems, while insufficient light can cause the plant to grow leggy and lose its vibrant color.
- Ideal Placement: Place it near an east- or north-facing window indoors, or under a shaded patio outdoors.
- Supplemental Lighting: If natural light is limited, consider using grow lights to provide consistent, filtered light.
2. Watering
Unlike desert cacti, Selenicereus anthonyanus enjoys regular watering during its growing season (spring and summer). However, it is crucial to avoid overwatering, as this can lead to root rot.
- Watering Schedule: Allow the top inch of soil to dry out between waterings.
- Winter Care: Reduce watering during the plant’s dormant period in fall and winter.
- Humidity Needs: As a tropical cactus, it appreciates higher humidity. Mist the plant occasionally or place a pebble tray with water nearby to increase moisture levels.
3. Soil and Potting
Epiphytic cacti like the Ric-Rac cactus require well-draining soil to mimic their natural growing conditions. Regular potting soil can retain too much moisture, so it’s best to use a specialized mix.
- Soil Mix: Use a blend of orchid bark, perlite, and cactus soil. Alternatively, mix equal parts cactus mix and peat moss for a lighter, well-aerated medium.
- Pot Selection: Opt for a pot with drainage holes to prevent waterlogging. Hanging baskets are particularly attractive for showcasing the plant’s trailing stems.
4. Temperature and Climate
Selenicereus anthonyanus thrives in warm temperatures and does not tolerate frost. Maintain a stable environment to keep the plant healthy and happy.
- Optimal Temperature Range: 60–80°F (15–27°C).
- Frost Protection: If you live in a colder climate, bring the plant indoors before temperatures drop below 50°F (10°C).
5. Fertilizing
Regular feeding during the active growing season will encourage healthy growth and improve the chances of flowering.
- Fertilizer Type: Use a balanced liquid fertilizer diluted to half strength.
- Frequency: Feed once a month from spring to late summer. Avoid fertilizing during fall and winter.
6. Pruning and Maintenance
Pruning helps maintain the plant’s shape and encourages new growth. Remove any damaged or dead stems with clean, sharp scissors.
- Propagation: Pruned stems can be propagated easily by placing them in moist soil or water until roots develop.
7. Encouraging Blooms
Getting the Ric-Rac cactus to bloom requires patience and the right conditions. Mature plants (typically 2–3 years old) are more likely to flower.
- Light and Temperature: Provide consistent, bright light and slightly cooler nighttime temperatures during the fall.
- Dormancy Period: Reduce watering and stop fertilizing during late fall to simulate the plant’s natural dormant cycle.
- Timing: Blooms are more likely to appear in spring or summer after a proper dormant phase.
8. Common Issues and Solutions
a) Yellowing Stems
- Cause: Overwatering or poor drainage.
- Solution: Check the soil and adjust your watering schedule. Ensure the pot has adequate drainage.
b) Leggy Growth
- Cause: Insufficient light.
- Solution: Move the plant to a brighter location or add supplemental lighting.
c) Pest Infestations
- Common Pests: Mealybugs and spider mites.
- Solution: Treat with insecticidal soap or wipe the stems with a mixture of water and neem oil.
d) No Blooms
- Cause: Lack of proper dormancy or insufficient light.
- Solution: Follow guidelines for reducing water and ensuring bright light during the plant’s active season.
