Polystachya caffra Plant Care

Polystachya caffra (Polystachya puberula) belongs to the Orchidaceae family within the Polystachya genus. Polystachya caffra is native to western and west-central tropical Africa. Polystachya caffra is also known as Polystachya puberula var. caffra.

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

Leaf size: approximately 6 inches.

Polystachya puberula 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.

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

Polystachya puberula grows best at temperatures of 65–80°F. Polystachya caffra prefers humidity levels of 60–80%. 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 Polystachya caffra to prevent waterlogging, which leads to root rot and fungal issues.

Feed Polystachya caffra 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.

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