Care
Light exposure
Grow coralline orchid in partial shade to full shade, in woodlands or near trees. This terrestrial orchid dislikes direct sun exposure and prefers a cool, humus-rich environment, close to its natural forest habitat.
Soil
Rich, well-draining soil is essential. Choose an acidic to neutral substrate enriched with leaf mold, peat, or coarse compost, which will mimic natural forest humus.
Watering
Keep the soil slightly moist during the growing period, without stagnant water that could rot the coral-like rhizoid. Reduce watering in winter during dormancy. Rainwater or gentle misting is ideal.
Fertilizer
A moderate application of compost or diluted organic fertilizer in spring is sufficient. This wild orchid dislikes excess nutrients; prefer a light annual substrate amendment rather than intensive fertilization.
Pruning and maintenance
No pruning is necessary. Let stems and flowers develop naturally, then simply remove dry foliage at the end of the season. Gently clean around clumps to prevent clogging.
Diseases and pests
This orchid is generally robust in natural conditions. Watch for stagnant excess moisture that promotes fungal rot. In containers, ensure optimal drainage and regular aeration to prevent mold development.
Did you know?
Coralline gets its fascinating name from its rhizoid, which resembles white or pink coral branching. This chlorophyll-free orchid relies entirely on mycorrhizal symbiosis to absorb nutrients, making it a rare myco-heterotrophic orchid and valuable for botanical research in forest ecology.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
