Most species are native to tropical and southern Africa, Madagascar, Réunion, and the Arabian Peninsula. The first molecular phylogeny of the genus involved comparing the nuclear ribosomal ITS1, 5.8S rDNA and ITS2 sequences and showed that Herschelia and Monadenia were nested in a paraphyletic disa. Disa, genus of about 175 species of terrestrial orchids (family Orchidaceae). The Disa orchid is a unique orchid that requires completely different care than other orchid species.

Most species are native to tropical and southern Africa, and some more are native to the Arabian Peninsula, Madagascar and Réunion.

Is a DISA an orchid?

If you have the patience and know-how to grow a disa orchid, this is a striking, unique and eye-catching ornamental plant. Red disa (Disa uniflora), a South African species, produces pink and scarlet flowers and is cultivated as an ornamental plant. The Disa orchid does not have pseudobulbs, but consists of small stems (rosettes) that reach 70 cm in height. Some species reach 90 cm in height and are densely covered with leaves. For the past few years, I've kept my disa grow unit with all my tropical orchids in my greenhouse.

The inside of the tray is six inches deep, just above the height of the pots I use for the disas.

How do you grow disa-orchids?

The

Disa orchid is very sensitive to bright sunlight and can not only burn itself, but also stay in development for a long time. Many experienced gardeners refuse to grow their own disa-orchid because they are so easy to care for. As a substrate, it is recommended to use a mixture of white peat and peat moss with the addition of 10-15% coarse sand, several pieces of charcoal and 3-5% ground moss, as well as planting in pure peat moss. In their natural habitat in Central and South Africa, they grow along streams whose roots are constantly in the water.

Disa is a land orchid and is therefore grown exclusively in pots (preferably from unbaked clay).

Do Cattleya's need hibernation?

Because cattleya roots need a lot of airflow, use an open potting mix like fir bark, which is supplemented with small bits of wool rock for added moisture and charcoal to keep the mixture from condensing. Those who have experience growing (or trying to breed) Cattleya Dowiana are aware of the tricky nature of this species. This allows you to easily access the information you need to take care of your Cattleya orchids in the best possible way. This explains the weak growth and the burnt leaf tips on plants that are artificially supplied with extra long day lengths.
