The Gymnadenia are easy to grow in the garden and are not very demanding in terms of their substrate.
The young Gymnadenia plants emerge as of April and spread their foliage during spring. The flowers appear at the end of spring (May, June). In autumn, the foliage yellows then fades before disappearing completely for the winter dormancy period. When the leaves have completely faded, the stems can be cut, preserving a height of 5cm.
Over the years and following the successive growth and dormancy cycles, Gymnadenia not only become stronger but also multiply, thanks to the annual appearance of new bulbs.
During the winter, the plant persists in bulb form and develops new shoots in the spring.
Gymnadenie appreciate a light and well-aired substrate. Airing the soil by means of compost for hardy perennials is recommended.
For an optimal result, add lava stone (vulca), and/or bark chippings.
Of full light or light shade, these undemanding hardy orchids like a dry or a sodden substrate and can be cultivated at the banks of ponds or bodies of water.
Of full light or light shade.
Fertilisation and Pesticide Treatments
If necessary, protect the tender young shoots against slugs, during their emergence in spring.
