CATTLEYA Orchid Care

CATTLEYA (cat-LAY-a) - Cattleyas have earned the reputation as the "Queen of Orchids" and are known to the public as the ultimate in floral corsages. While some naturally occurring species are offered by growers, the most popular plants are man-made hybrids derived from combining Cattleyas with some of their close relatives to produce a wide range of colors, sizes and forms.

Cattleya is a genus of 113 species of orchids from Costa Rica to tropical South America. The genus was named in 1824 by John Lindley after Sir William Cattley who received and was the first to bloom a specimen of Cattleya labiata. Wikipedia

Scientific name: Cattleya

Rank: Genus

Higher classification: Orchidaceae

Lower classifications: Cattleya schofieldiana, Cattleya nobilior, More

Temperature: The ideal day temperature is 75-85 degrees F., while the ideal night temperature is 60-65 degrees F. Occasional temperature extremes are tolerated if exposure is not prolonged.

Light: Cattleyas and their relatives require a good amount of light. They enjoy full sun in the morning, but will require shading from about 11am-3pm; less shading will be necessary in the late afternoon. Their leaves should be a light green color, and a darker green color indicates too little sun.

Water: Basically, cattleyas grow best when their potting medium becomes dry in between waterings. These plants are epiphytes in nature, (i.e. growing on top of trees) and are used to drying out between the rains of their natural habitat.

Repot: Cattleyas should not be repotted unless the plant have outgrown the pot (every 2 or 3 years) or when the potting medium begins to deteriorate. Or when the mixture become sour, does not drain rapidly and is invaded by snow mold or shows green mold on the surface. A coarse medium such as medium-grade Fir-bark, or coarse-grade Fir-bark will work well.

Feeding: High-nitrogen fertilizers (25-9-9) can be used year-round at one teaspoon per gallon of water. Feed once a month.
Cutting Dead Flower Spike: When the last flower drops, cut your flower spike all the way down the stem. Apply a pinch of cinnamon powder or melted candle to seal the wound. Continue caring for it and wait for a possible rebloom.
