IDENTIFY ODONTOGLOSSUM CRISPUM
Odontoglossum crispum is found Colombia. It grow as epiphytes in clearings and along forest edges on the trunks and main branches of oak trees in partial shade and occasionally full sun at altitudes of between 1800 m and 3000 m, including in the eastern Cordillera in the departments of Cundinamarca and Boyacá and in the Andes of southern Colombia in the departments of Cauca, Putumayato and Nariño.
It is a medium sized, cold growing epiphytic species with broadly ovoid or oblong-ovoid, ancipitous, 6 cm long pseudobulbs carrying 2 apical, suberect, linear-lanceolate, acute, narrowing below into a long, narrow, conduplicate, petiole-like base, 10 to 30 cm long leaves.
The Curled Odontoglossum has a varied blooming season, but most often in winter, with fragrant, variable in color and size flowers on an axillary, to 45 cm long, 8 to 20 flowered inflorescence with a raceme at the upper third with a few short basal branches that comes from the side of the newest forming pseudobulb. The flowers are white with a gently pink blush, about 7.5 cm in diameter. Sepals and petals are wide, on the edge of terry and slightly wavy. The lip is white with a small fraction of red-brown spots, inside is yellow. Sometimes sepals and petals may be with red-brown spots or stripes.
ODONTOGLOSSUM CRISPUM CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Odontoglossum crispum loves the bright sun without access to direct sunlight, so during the midday it must be put behind a curtain or into the shade of other plants.
Temperature:
This orchid belongs to a moderately cold temperature regime: Summer temperature at 16-24 ° C; Winter temperature at 7-18 ° C. The ideal temperature for growing is 7-16 ° C. To successfully grow this species, the night temperature should always be at least 3 ° C lower than the daytime temperature.
Humidity:
The Curled Odontoglossum needs relatively high humidity. The minimum indicator should be at least 70%. If, however, it is impossible to avoid exposure to high temperatures, the humidity of the air must be increased together with the temperature. This will help the plant better survive the forced heat. The humidity of the air must be at least 80-90%.
Substrate, growing media and repotting:
It is strongly recommended to grow Odontoglossum crispum in small pots which allow the substrate to dry up as quickly as possible, otherwise at relatively low temperatures, the roots and the lower part of the plant will rot. The substrate must be very well breathable, therefore in its quality the mixture of large pieces of coniferous bark with foam plastic is the best.
Watering:
During the period of new growth this orchid needs frequent and abundant watering. Excess water during watering should flow freely out of the pot, as the stagnation of water both inside the pot and in its pan can very quickly lead to decay of the roots and the lower part of the plant. The substrate between waterings should dry well.
In hot summer days when finding orchids outdoors, regular spraying of the outer part of the plant is recommended. This will help the orchid to better tolerate the forced heat. At home, spraying does more harm than good, as it creates favorable conditions for the development of various kinds of fungal diseases , so it is strongly recommended to abandon it.
Fertilizer:
During the period of new growth, this type of orchid is fertilized once every 2-3 weeks in 1/4 of the fertilizer concentration indicated on the package. Too concentrated fertilizer adversely affects the roots of Odontoglossum crispum, they turn black, become slimy and die.
For the prevention of salinization of the substrate, it is strongly recommended to rinsed it well every six months. To do this, the pot with the orchid should be placed under a stream of warm water and several times well rinsed.
Rest period:
To stimulate flowering Odontoglossum crispum needs a clearly defined period of rest. It begins immediately after the maturation of new bulbs, i.e. when new young shoots reach the size of the old, and is that the orchids contain much drier and colder than usual, and do not fertilize. The temperature during this period should be at night about 13-14 ° C, and in the daytime no more than 16 ° C. Watering the orchids significantly reduces, but does not stop completely. Water should be small every two weeks. It is highly recommended not to allow the pseudobulb of the plant to shrink too much, it may adversely affect its further well-being. After the appearance of peduncles, the rest period ends: irrigation resumes in the usual volume, and the overall temperature of the content rises.
