Brassocatanthe (Maikai × Star Ruby)

Care Tips:

• Light:

  • Bright, indirect light is ideal.

  • Morning or filtered south/east light works best.

  • Too little light → poor flowering, dull leaf color; too much → leaf burn.

  • Healthy leaf color: light to medium green.

• Temperature:

  • Day: 22–28°C (72–82°F)

  • Night: 16–20°C (61–68°F)

  • Slight night cooling encourages flower spike formation.

  • Avoid frost or sudden temperature drops.

• Watering:

  • Keep the medium evenly moist but well-drained.

  • Spring–summer (active growth): water every 3–5 days depending on conditions.

  • Autumn–winter (rest period): reduce watering, do not let the medium dry out completely.

  • Avoid waterlogging to prevent root rot.

• Humidity:

  • Optimal: 50–70% relative humidity.

  • Increase humidity with a humidifier or misting if air is dry.

  • Ensure good air circulation to prevent fungal issues.

• Fertilizer:

  • Active growth (spring–summer): fertilize every 2 weeks with a diluted orchid fertilizer (½–¼ strength).

  • During flowering: reduce nitrogen, increase phosphorus and potassium to support blooms.

  • Winter: cut back or stop fertilization.

• Potting / Medium:

  • Use loose, well-aerated epiphytic orchid mix: tree bark + perlite + some sphagnum moss.

  • Repot every 2–3 years or when medium breaks down.

• Flowering:

  • Typically flowers in spring–summer, but some clones may bloom multiple times a year.

  • Promote flower spikes with sufficient light, temperature variation, and proper fertilization.

• Pests & Problems:

  • Common pests: aphids, spider mites, scale insects.

  • Control with orchid-safe insecticides or mild soapy water.

  • Prevent fungal issues by avoiding stagnant water and maintaining good ventilation.

• Extra Tips:

  • Can be mounted on tree bark or placed in hanging baskets to mimic natural epiphytic growth.

  • Bct. hybrids produce large, showy flowers and often have a gentle fragrance.
