How to Grow and Care
Sun Orchids can be very tricky in cultivation. However, most are fairly amenable and some are very easy. All plants are summer dormant and rest as tuberoids. Plants emerge in late summer and flower in late winter, spring and early summer.
Culture as sunny as possible. In milder climates garden culture is possible. Frost hardy up to 23°F (-5°C). Regular watering during the growing period is essential. Fertilize monthly until flowering. Reduce watering with the onset of flowers and stop as the leaves die back. Completely dry during dormancy. Occasionally a light spray of water for small plants and seedlings to prevent dehydration. If grown inside, move plants temporary outside in late summer as cool nights and some rain will stimulate plants into the new growing season… – See more at: How to Grow and Care for Sun Orchids.
