Due to their beautiful flowers, the Cattleya are among the best-known and most popular orchids. Care is not difficult under certain conditions. First and foremost, humidity is required in the growing season. The posture in the room is no longer necessary. Even if successes are achieved occasionally. It is necessary to place it in a closed plant window or under conditions similar to a greenhouse. The decisive factor is compliance with the rest period and the full use of the growing time. If one considers the influences of the growth factors, the following picture emerges over the course of the year:
light: March-April light shade, May-August partial shade, September light shade, October-January full light.
temperature: March-May warm, June-September tempered, lots of air, Temperate October to February, no ventilation.
humidity: March-September evenly moist, but no stagnant wetness, splash a lot. September-October moderately humid, November-February moderately dry, however, be careful not to shrink the pseudobulbs and leaves.
These details are based on adults, flowering plants related, which are in perfect condition. Weak or root diseased specimens do not tolerate extreme conditions. Young plants always need uniform moisture until they are ready to flower, slightly higher temperatures and stronger protection from direct sunlight from March to September.
There are different opinions about when to transplant. According to old tradition, it should be in May, exceptionally from mid-April. External characteristics are the beginning of new root growth and the beginning of shoots. Both are often the case at the end of February-beginning of March; then you should not hesitate and take this often or usually quite drastic measure for the plant as soon as possible. Progressive opinion goes there, to carry out the transplanting before the start of the shoot development. The inevitable disruption is thus reduced.
Young plants are repotted every year. When it is ready to flower, this is only necessary every two years.
There are enough recipes for plant substances. Compare the section "The Plant Substances". The standard mix 1 and the variations 2 a-2c are all suitable for Cattleya, tentatively 2d.
The technique of transplanting is explained in detail in the corresponding section and therefore does not need to be discussed again in detail here. The same applies to further processing.
David Sander recommends the following temperatures for Cattleya in his book "Orchids and their cultivation": Minimum night temperature + 17 ° C, during the day +18 to + 21 °C; + 18 ° C at night in the spring months, during the day + 21-24 ° C. With the beginning of autumn at night + 16°C; sufficient at the time the plants are ripe + 12-15°C.
Gelbe Cattleya, like C. dowiana and the hybrids bred from it always require a slightly higher temperature; the minimum is + 18 ° C.

The most important generic bastards
Brassocattleya = Cattleya x Brassavola or vice versa, strongly growing, keep only moderately warm; if the temperature is too high, bud growth overgrows too early. Flowers mostly large, handsome, z.T. with a strongly fringed large lip. T.
Brassolaeliocattleya = Brassavola x Laelia x Cattleya or vice versa. Like Brassocattleya, T; yellow W / T.
Laeliocattleya = Laelia x Cattleya or vice versa. Vigorous and without other demands than the parents. All shades of white, yellow, Purple to reddish and red: T; yellow W.
Sophrocattleya = Cattleya x Sophronitis or vice versa. Caring for them is a little more difficult, with. T. the growth is weaker and the willingness to flower is reduced. These disadvantages are offset by the particular beauty of some breeds. Same goes for
Sophrolaeliocattleya = Sophronitis x Laelia x Cattleya and vice versa. T/W.
Rolfeara combines Brassavola x Cattleya x Sophronitis. T/W.
Potinara is the name of the combinations Brassavola x Cattleya x Laelia x Sophronitis. T.
The number of other generic bastards with Cattleya as a parent is considerable and is constantly increasing. Maintaining them is often not easy, because the plants, under the influence of more or less contradicting genes, make special demands on the parents, which one must first recognize or feel.
