Conical Polystachya Plant Care

Conical Polystachya (Polystachya concreta) belongs to the Orchidaceae family within the Polystachya genus. Conical Polystachya is native to tropical and subtropical America, Africa and Asia.

Conical Polystachya displays an epiphytic, clumping orchid growth habit, reaching up to 2 ft tall with a spread of approximately 1 ft. Conical Polystachya produces small, delicate flowers in various colors like white, pink, purple.

Leaf size: approximately 8 inches.

Polystachya concreta requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Conical Polystachya thrives in bright indirect light. Avoid placing Conical Polystachya in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Polystachya concreta grows best at temperatures of 65–80°F. Conical Polystachya prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Loose, well-draining orchid mix with bark and perlite. Good drainage is essential for Conical Polystachya to prevent waterlogging, which leads to root rot and fungal issues.

Feed Conical Polystachya every 2 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

Repot every 1-2 years after flowering. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Conical Polystachya can be propagated through division, back bulbs, keiki propagation. Similar propagation techniques also apply to polystachya bicalcarata plant care, which shares the same genus.
