How to Grow Epiphyllum Cacti

Light

Epiphyllum cacti thrive in bright, indirect light, making them ideal candidates for placement near east or west-facing windows.

Direct sunlight should be avoided, as it can lead to leaf and flower scorching.

During the winter months, when daylight hours are shorter, providing supplemental lighting may be necessary to maintain optimal growth and flowering.

Temperature and humidity

Maintaining suitable temperature and humidity levels is essential for the health and vitality of Epiphyllum cacti.

During the growing season, which typically spans spring to fall, aim to keep temperatures within the range of 65-85°F (18-29°C).

In winter, when growth slows, slightly cooler temperatures of 50-60°F (10-15°C) are acceptable.

Additionally, these cacti thrive in high-humidity environments.

To increase humidity levels, mist the plant regularly or place it on a pebble tray filled with water to create a microclimate around the plant.

Soil and drainage

Providing Epiphyllum cacti with well-draining soil is crucial to prevent root rot and ensure optimal growth.

Opt for a specialized cactus and orchid mix, or create your own by combining peat moss, perlite, and bark chips.

Adding coarse sand or perlite to the soil mixture further enhances drainage, promoting healthy root development and reducing the risk of waterlogged soil.

Watering

Epiphyllum cacti have specific watering needs that should be carefully managed.

During the growing season, water the plant thoroughly when the top inch of soil feels dry to the touch, allowing excess water to drain away freely.

However, exercise caution to avoid overwatering, as this can lead to root rot.

In winter, reduce watering frequency to mimic the plant’s natural dormancy period, allowing the soil to partially dry out between waterings.

Fertilization

Regular fertilization is essential for promoting healthy growth and flowering in Epiphyllum cacti.

During the active growing season, apply a balanced liquid fertilizer diluted to half strength every 4-6 weeks.

Avoid fertilizing during the winter months when the plant is dormant.

Additionally, incorporating a layer of organic mulch around the base of the plant helps retain moisture, suppresses weeds, and provides slow-release nutrients over time.

Pruning and maintenance

Epiphyllum cacti may require occasional pruning to remove dead or damaged stems, promote branching, and maintain an attractive shape.

Use sterilized pruning shears to make clean cuts, and promptly remove any diseased or pest-infested sections to prevent spread.

Regular monitoring for pests such as scale insects or mealybugs helps prevent infestations and ensures the continued health of the plant.

Potting and repotting

Epiphyllum cacti prefer slightly cramped roots, so only repot when necessary.

Choose a pot one size larger than the current one with proper drainage.

Opt for a well-draining cactus mix. Repot in spring after blooming, allowing recovery for the active growing season.

Propagation

Epiphyllum cacti can be propagated from stem cuttings or seeds. 

From stem cuttings

• Select a healthy stem with at least one node.
• Make a clean cut, and let it callus for a few days.
• Plant in well-draining soil, ensuring the buried node.
• Water lightly and place in a warm, bright, indirect light spot.

From Seeds

• Sow seeds in shallow, well-draining soil.
• Press seeds into the soil, and maintain consistent moisture.
• Place in a warm, bright location with indirect sunlight.
• Cover for humidity and uncover gradually after germination.

Maintenance and Troubleshooting

Pests and diseases

Epiphyllum cacti generally boast resistance to pests and diseases.

Despite their hardiness, common cactus nuisances like scale insects and mealybugs can pose a threat.

Vigilance is key—observe for signs of infestation, and if detected, promptly treat the cactus using horticultural oil or insecticidal soap for effective control.

Flowering

Achieving vibrant blooms with Epiphyllum cacti requires attention to their unique needs. Optimal flowering conditions include:

Lighting

• Provide bright, indirect light for the cactus, promoting robust blooming.
• Avoid exposing the plant to direct sunlight, which may lead to leaf and flower damage.

Moisture

• Maintain consistent moisture levels, especially during the growing season.
• Adequate watering contributes to healthy blooming cycles and prevents stress on the plant.

Fertilization

• Apply a balanced fertilizer during the growing season to enhance flowering.
• Choose a fertilizer specifically formulated for cacti and succulents, diluted as recommended.
