Care
Watering
Keep the soil consistently moist during growth and flowering, particularly in spring. Reduce watering in summer and autumn once the foliage has disappeared. Avoid standing water that could rot the underground tubers.
Light Exposure
Prefer a semi-shaded location, especially in the afternoon. In cool regions, a part-sunny exposure promotes flowering. Protect from overly intense midday sun rays.
Soil and Substrate
Choose soil rich in organic matter, slightly chalky and well-draining. Incorporate compost or peat to improve structure. Frog orchid appreciates the moist soils of natural meadows.
Fertilizer
A moderate application of balanced fertilizer in spring is sufficient. Avoid excess nitrogen, which would promote foliage at the expense of flowering. In natural settings, it thrives on soil nutrients alone.
Pruning and Maintenance
No pruning is necessary. Let the foliage naturally die back in autumn. At season's end, clean up debris to prevent fungal diseases.
Diseases and Pests
Watch for rot caused by excessive moisture or poor drainage. Slugs can damage young shoots in spring. Good air circulation and well-draining soil minimize most problems.
Did you know?
The frog orchid has fascinated since antiquity: the Greeks believed that its double tubers symbolized virility, earning it its Mediterranean nickname. Its characteristic green inflorescence, resembling a tiny frog, makes it one of Europe's most discreet wild orchids and yet the most sought-after in damp meadows.
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.
