Disa Culture

This is primarily a South African genus. The Disa orchid is the floral emblem of the Cape Providence of South Africa. They are terrestrial found growing along the sides of stream banks and other wet areas at altitudes between 100m to 1200 m. The varieties most commonly grown in Tasmanian derive from the spectacular species uniflora. Colours can vary from brilliant orange, bright pink and yellow.

Disa Orchid

Protect from the heat but can tolerate temperatures near freezing. They can be grown outside under the protection of shady bushes. If grown in a shade house provide ample air movement and humidity. Do not allow plants to sit in water trays.

Potting Mix

Sphagnum moss is ideal but good quality sphagnum is not always available. A quality general plant potting mix with added course sand and perlite can be used. The mix should be free draining and not mud like.


Disa require more water than most orchids. Keep wet at all times during summer; lessen off during winter but always towards the wet side. Rain water is preferable, if no rain water is available fill a container with tap water and let sit for a day.


Apply soluble fertilisers at ½ rates, as well as seaweed based food. It is best to under feed rather over feed.


Flowers appear during spring until midsummer. They flower off last year’s growth which grows from a tuber. This growth will die after flowering.  During the flowering time small plants will appear and become the future flowering growths.


After the flowering growth dies, gently divide the new growths. The roots are very brittle. If in sphagnum moss re pot yearly, allow several years between other mixes.


White mealy bugs and aphids can be a problem. Treat with a commercial product such as eco oil. Slugs and snails should be treated with snail bait. Drying out in hot weather as well as becoming water logged over a long period of time will also place stress on the plant.
