For the best cultivation of the Dactylorhiza, place it in a partially shady place, or in one which enjoys a few hours of direct sunlight, in the morning and not during the hottest hours of the day, in order to avoid that the leaves may show some burns.
The dactylorhiza do not fear the cold, therefore they can also find room in the garden; if kept in a container, they can be sheltered in a cold greenhouse. It is advisable to protect them from the sun during the very hot days of the summer months and, in winter, do not put them in rooms with excessive heating.

The Dactylorhiza need regular watering, which should be done letting the soil stay slightly moist; usually they can bear short periods of drought. Check that the substrate does not allow the formation of water stagnations that can quickly cause the onset of root rot, which must be countered quickly to avoid serious problems to the health of the plant.
These orchids grow without any problems in any well drained, humus-rich, loose and light soil; for a correct development of the plant it is necessary to provide slow release granular fertilizer every 4-6 months. The epiphytic varieties need a substrate composed by sphagnum, chopped bark and perlite or charcoal, in order to allow the roots to have a good support, able to maintain the right degree of humidity.
The reproduction of these orchid plants can take place by seed, in autumn. If desired, it is also possible to practise root cuttings, or to divide the fleshy roots, to be buried in a substratum rich of humus, in the case of the terrestrial species, or to be placed in a container with sphagnum and bark, for the epiphytic plants.
Dactylorhiza: Pests and diseases
Generally, these orchids, being quite resistant, do not fear the attack of pests or diseases. However, they can show radical rottenness if the cultivation soil is not sufficiently drained or if the water supply is excessive.
