Plantscape Designs uses Cattleyas orchids in our interiorlandscaped offices, Boston , MA


The Corsage Cattleyas Orchid also used in our PDIplant designs interior offices in Boston, MA.




1. Cattleyas are among the most commonly grown orchids, and their culture is often used as the basis for comparison with other types of orchids.  Like most other cultivated orchids, cattleyas are epiphytes, or air plants.  They have well-developed water-storage organs (called pseudobulbs) and large, fleshy roots.  They should be potted in a porous, free-draining medium.  The most commonly used are fir bark, shredded tree-fern fiber, various types of rock, processed coconut fiber and lately, mixes based on peat moss and perlite.  Keep out of cold, dry air while in bloom.

2. Light
Sufficient light is important for healthy growth and flower production.
Provide  Bright light, some sun.  In the home, an east, west or lightly-shaded south window.  In a greenhouse, about 30 to 50 percent full sun.  Under lights, four 40 watt fluorescent tubes and two 40 watt incandescent bulbs directly over plants.  Plants should be naturally erect, without need of much staking, and of a medium olive-green color.  Dark green, limp foliage indicates too little light.

3. Temperature
Mature plants need a 15 to 20 F difference between night and day. Keep your orchids near cool north indoor  office windows for better interiorscape flowering blooms.

Provide  Nights of 55 to 60 F; days of 70 to 85 F.  Cattleyas can tolerate temperatures up to 95 to 100 F if shading, humidity and air circulation are increased.  Seedling cattleyas need temperatures five to 10 degrees higher than mature plants.

4. Water
Mature plants must dry out between waterings, especially in your interior office landscapes. Seedlings need more constant moisture.

5. Humidity
Cattleyas need 50 to 60 percent.  In your indoor ofice environment.

6. Fertilizer
Must be provided on a regular basis because most potting media have little fertilizer in it.
 The exact fertilizer you use will depend on the mix in which your plant is growing.  A good general rule is to use a balanced (10-10-10, 12-12-12 or similar ratio) fertilizer "weakly, weekly."  That is, fertilize every week at one quarter to one half of the recommended dilution.

7. Potting
Should be done every two to three years in spring before mix loses consistency (breaks down).  Pot firmly in media that have good aeration and ample drainage, allowing enough room for two years' growth.

At Plantscape Designs Inc., we frequently apply Cattelya orchids in our monthly flowering corporate arrangements for our interior office plant Boston, MA. environments.
