🌿 Plant Care

☀️ Sunlight

• Prefers bright, indirect light.
• Morning sunlight for 2–4 hours is beneficial.
• Avoid harsh afternoon sun, which can scorch the stems.

💧 Watering

• Water when the top 2–3 cm of soil feels dry.
• Keep the soil slightly moist during spring and summer.
• Reduce watering in winter, but do not let the soil remain completely dry for long periods.
• Avoid waterlogging.

🌡️ Temperature

• Ideal range: 18°C–30°C.
• Protect from temperatures below 10°C.
• Enjoys moderate to high humidity.

🌱 Soil

• Use a fast-draining cactus or orchid mix.
• A good mix:
  • 40% cocopeat
  • 30% orchid bark
  • 20% perlite or pumice
  • 10% compost or leaf mould

🪴 Pot

• Grow in a pot with drainage holes.
• Hanging baskets are ideal as the stems cascade beautifully.
• Repot every 2–3 years or when root-bound.

🌿 Fertilizer

• Feed once every 4–6 weeks during the growing season with a balanced liquid fertilizer diluted to half strength.
• Stop fertilizing during winter dormancy.

🌸 Flowering

• Produces large, fragrant white to cream flowers that usually bloom at night.
• Mature plants flower more reliably after experiencing slightly cooler temperatures and reduced watering during late autumn.

✂️ Pruning

• Remove damaged or dried stems.
• Trim overgrown stems to maintain shape.
• Healthy stem cuttings root easily and can be propagated.

🐛 Common Problems

• Yellow stems: Overwatering or poor drainage.
• Wrinkled stems: Underwatering.
• Soft, black stems: Root or stem rot due to excess moisture.
• Mealybugs or scale insects: Wipe with neem oil or insecticidal soap.

🌱 Propagation

• Take a healthy stem cutting (10–15 cm).
• Let the cut end dry for 2–3 days.
• Plant in a moist, well-draining mix.
• Keep in bright indirect light until roots develop (about 3–6 weeks).
