How to grow queen of the night
Overview
Queen of the Night is an epiphytic cactus grown for its spectacular, fragrant night-blooming flowers. It thrives in warm, humid conditions with filtered light and excellent drainage.
Soil Preparation
Use a coarse, open mix of orchid bark, perlite, and charcoal. Avoid garden soil or heavy potting mixes. Aim for a pH of 5.5–6.5 and ensure excellent drainage.
Growing Guide
Plant in a coarse, well-draining orchid mix or attach to a tree fern slab. Position in dappled shade, avoiding direct afternoon sun. Water deeply when the top 2 cm of mix dries, but reduce frequency in winter. Space plants 30–40 cm apart in a hanging basket or sheltered pot.
Care
Feed monthly in spring and summer with a balanced liquid fertiliser at half strength. Prune after flowering to remove spent stems and shape the plant. Repot every 2–3 years into fresh orchid mix.
Companion Planting
Grows well with other epiphytic cacti like Rhipsalis and Schlumbergera. Avoid planting near heavy feeders such as ferns that compete for moisture.
Common Pests & Risks
Scale insects and mealybugs are common; treat with a soft brush dipped in neem oil or a systemic insecticide. Root rot occurs if the mix stays wet; ensure drainage and reduce watering in cool weather.
Troubleshooting
Yellow stems: overwatering or poor drainage—reduce water and check mix. Brown edges: sunburn—move to more shade. Bud drop: sudden temperature change or dry air—maintain stable conditions. No flowers: too little light or overfertilising—adjust position and feeding.
