A collection of Catasetum related links to items of interest found on the Internet, that do not fit in any of the three main catagories.
Catasetum, abbreviated as Ctsm in horticultural trade, is a genus of showy epiphytic Orchids, family (Orchidaceae), subfamily Epidendroideae, tribe Cymbidieae, subtribe Catasetinae, with 166 species, many of which are highly prized in horticulture.
The cultural information below is a generalization and will apply in most situations; however each grower and growing environment is different. I encourage you to make adjustments based on your experience and growing conditions.
Catasetinae have a distinctive growth and rest period (dormancy). For best plant growth it is important to understand and respect these growth phases. When the plants are in active growth maintain constant root zone moisture and fertilize regularly. This is essential to optimizing the development of new growth. When the plants are dormant little or no water is needed as the pseudobulbs store enough moisture and nutrients to survive the dormancy.
Catasetinae plant culture is not difficult. All it takes is an understanding of the seasonal growth patterns. The plants vegetative state signals to the grower their changing needs. Interpret the signals and make the appropriate cultural adjustments. Here is what to look for:
The Sub-tribe Catasetinae includes the Genera Catasetum, Clowesia, Cycnoches, Dressleria, and Mormodes. Culture of Dressleria even though once included in the genus Catasetum is different. Do not try to grow Dressleria species using these suggestions.
The plants of Tribe Catasetinae are widespread in lowland tropical areas of South and Central America up to elevations of about 1200-1500 meters. Most of the discussion which follows pertains particularly to Catasetum a genus with 80-120 species. The plants can generally be found growing on trees, tree stumps, or old fence posts. The plants are weedy and tend to be fairly abundant once you find the first plant or plants.
