For a correct cultivation, these orchids should be placed in a shady position, as the direct sun causes quickly showy burns on the leaves; choose a bright and very ventilated position, both in summer and in winter. The cultivation in house should be done by placing the plant in an environment where the climate is cool, avoiding to put the plant near sources of heat.

In nature, the dysa uniflora grow along rivers or on the shores of lakes, in mountainous places, and therefore enjoy fresh and moist soil; for this reason it is advisable to water the plant regularly, at least every 2-3 days, letting excess water flow freely from the vase; to increase the ambient humidity, it is also advisable to vaporize the area around the plant, avoiding moistening the flowers and leaves.
Use only demineralized water; at least once a month add to the water of the watering of the specific fertilizer for orchids, in very low concentration.
Check that the substrate provides the right degree of drainage to prevent the roots from remaining in contact with excess water which can lead to dangerous rottenness.
The dysa uniflora need a very well drained substratum; an ideal compound can be prepared by mixing peat, sand, perlite and bark, in such a way that the substratum is slightly acidic, well drained, but also able to retain a little of humidity. These plants are to be repotted every 2-3 years, in order to avoid that tubers and roots remain without space available for growing; this operation takes place preferably after the flowering.
In order to avoid damaging the roots, which can be rather fragile, wet the soil before proceeding with the repotting.
The multiplication of these orchids for having new specimens takes place by division of the tubers, detaching the new ones from the mother plant. It is also possible to sow the orchids, using the fresh seeds, even if this operation can present greater complications and lead to the birth of flowers not equal to those of the mother plant.
Disa uniflora: Parasites and diseases
Be careful with aphids, red spider mite and root rot. To avoid root rot, it is sufficient to check that the substrate ensures a high degree of drainage; for parasites there are special insecticide products that must be used carefully, however, trying to avoid spraying them on the flowers.
