Brassia bidens
Also known as: The Two or Brassia lanceana var. viridiflora in the subfamily: Epidendroideae
Native to: Amazonas - Brazil Amazonas - Peru Guyana Loreto - Peru
General Information
The Two is a medium to large sized sympodial warm to hot growing epiphytic or terrestrial orchid belonging to the sub family Epidendroideae native to Brazil, Peru and Guyana.
Plant Description
Sympodial. Grows to 21-45cm. Each new growth has numerous leathery elliptic, lance shaped, oblong shaped leaves that grow to 2.2-50cm long. Pseudobulbs grow to 2.5-15cm
Care Notes
These orchids have a fine root system that can quickly die back if left dry for too long, but also does not like to be kept wet, so water regularly but ensure that the mix is dry before watering.
Climate
Grows at low to high elevations. Rainfall ranges from 81mm to 244mm per day, heaviest in May and lightest in January. Humidity ranges from 77% to 89%, highest in June and lowest in March. Temperature ranges from 13C to 27C, highest in February (16C to 27C) and lowest in September (13C to 26C).
Watering
These orchids prefer a wet-dry cycle between waterings, they should be watered frequently but only when the moisture is approaching dryness, where the pot feels light and/or the media looks dry. Keep an eye on mounted orchids in warm weather as they may dehydrate quickly.
Fertiliser
These orchids do not need to be regularly fertilised and roots may be sensitive to salt build-up, dying back and therefore impairing the plants growth or even killing it.
If fertilising, use half to quarter of the recommended amount of fertiliser. If they receive fertiliser as part of a collection, be sure to flush out the pots regularly with fresh water and monitor the roots by checking how much resistance is given by the plant when nudged in its pot or mount. If the plant becomes wobbly or loose, repot in fresh mix or rinse the media/mount thoroughly and do not fertilise for at least 3 months.
This plant is sensitive so apply fertiliser sparingly at one quarter recommended strength or less.Potting
These plants can be sensitive to repotting though should not require repotting regularly. Repotting should be done when the mix has broken down to the point that it doesn't absorb water or holds onto water for far too long, usually the plant shows a decline in growth as well.
The mix should be free draining, with a blend of 30% inorganic ingredients such as coarse sand, gravel or perlite, mixed in with about 70% organic ingredients such as peat, leaf litter or decomposed bark. Avoid commercial potting mixes as they can vary wildly and may contain "wetting agents" that can hold onto water for loo long, causing rotting and stunted growth.
Repotting is best done annually.
