The Dactylorhiza are easy to grow in the garden and are not very demanding in terms of their substrate.
The young Dactylorhiza 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, Dactylorhiza 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.
Dactylorhiza are very cold-resistant orchids and do not require any special protection in winter.
Dactylorhiza 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.
Most Dactylorhiza are fond of wet to sodden areas and can be cultivated at the banks of ponds or bodies of water.
According to the varieties, the ideal place will be sunny or semi-shaded.
Fertilisation and Pesticide Treatments
If necessary, protect the tender young shoots against slugs, during their emergence in spring.
