Coelogyne Rochussenii - Mature Plant

This plant thrives in bright indirect light, which means it needs a well-lit space without harsh direct sunlight. Ideal locations include east or north-facing windows, or spots near south or west-facing windows with filtered light through a sheer curtain to protect its foliage.

Water deeply 2–3 times a week, depending on weather and soil type. Early morning or late evening is best. Increase frequency during peak summer or dry spells.

For these plants, use a growing medium composed of 40–50% orchid bark (medium to large) for airflow and root anchoring, 20–30% charcoal to absorb impurities, 10–20% perlite or pumice for drainage, and 10–15% coco chips or husk to retain light moisture. Optionally, add a small amount of sphagnum moss in dry conditions to maintain humidity. This blend ensures excellent aeration and prevents root rot, ideal for thriving in Indian climates.

For these plants, use a balanced orchid-specific liquid fertilizer (such as 20-20-20) diluted to one-quarter to half strength, applied every 2 weeks during active growth. During blooming or rest periods, reduce feeding to once a month or pause it altogether.
