Near the pond, riverside of course good, at least to trees or bamboo and the sun shade net, reduce temperature decrease. BON (best placed in wooden or steel), if on the ground to pad to brick home balcony can also use tin small leather water jar storage water cushion brick maintenance, increasing humidity. 3, appropriate shade: orchids mostly belong to half shade plant, most species are afraid of direct sunshine, need appropriate shade. Orchid in the middle of April, you can go to the net window, and more according to the sun to promote its growth. In May, except for the midday sunshine, it can take 6 hours. Since June, it has been all-weather shade. After October, it can be fully maintained except Zhongyang. Remember the saying, "leaves are good, but Yang is many."". 4, reasonable fertilization: Orchid this to eat "vegetarian", fertilization depends on the selected basin soil and growth situation. Any growth, no disease can be fertilized, poor growth is not suitable for fertilization or a small amount of fertilizer. The newly planted orchid without the root of the pot should be fertilized after 1 to 2 years. 6 - July when the orchid buds elongation of about 1.5 cm, every three weeks once a maturity (fertilizer concentration to dilute appropriate about 10%). Do not use chemical fertilizer, such as the case of high temperature season should fertilization, from 8 to September every two to three weeks once a dilute liquid fertilizer. The orchid should be fertilized in the evening and watered in the morning. It is called "backwater"". 5, proper watering: Orchid watering, rain and spring water for good, tap water or Taomi Shui need overnight use. When pouring from the basin edge can not be poured, poured in the bud. The amount of water should be in accordance with the temperature, soil dryness and basin growth and bluegrass. Most of the leaves are watered and the leaves are thin. 4 May - bud not soil, basin earth is dry, wet and sprout perishable; 6 - September for orchid bud growth period, the amount of water should be increased, sunny day morning or watering time, avoid watering sun at noon. In autumn, the amount of water can be reduced, and the leaf spray water can be used to keep the soil moist. In winter, the water quantity should be controlled, and the "80% dry and 20% wet" should be maintained. 6 evening, the growth in the air: Orchid spray and wet environment, so in the dry season, in addition to shade, the evening must also spray, increase air humidity, reduce the temperature; but also to the ground watering potted orchid (table), "hot and cold" can stimulate the growth of orchids. 7, wind rain: "February ghost wind" old leaves yellow back is a normal phenomenon, can cut off the dead twigs and withered leaves. The orchid may drizzle, But avoid rainy, rain or rain, otherwise easy to rotten heart, rotten leaves. Rain season may be appropriate to sprinkle a small amount of plant ash. 8, flowers: Orchid Culture in pruning to cut off the leaves and often yellow leaf disease. Benefit ventilation.

Ciaran inflorescence last blossom a week, away from the pelvic surface 3 cm cut. 9, cold warm: orchids because of different varieties, different origin, cold resistance is not the same strength, so the winter into the room and the location of indoor placement is not the same. Cold blue, autumn orchid, orchid grows in the south, in the appropriate temperature of 5 degrees into the room (or window fence), and as far as possible in the South Xiangyang department. Spring, cold Ciaran ability, can be up to 0 DEG C when it entered the room, placed in the northeast can be. In sunny weather, at noon or so, facing the South or south-east to open the window, pull the net ventilation. Autumn orchid can not open windows when it is sunny at 1 - 2 degrees centigrade. Of course, there are greenhouse, available electro-optical heating. 10, disease prevention and treatment of insects: basin soil generally to carry out sterilization treatment (hot sun exposure can also), in case of disease. Orchid is the most prone to blight in the rainy season of high temperature, a small amount can be used wet brushing, basin volume available 500 - 800 times Bordeaux or Topsin, sprayed once every 7 to 10 days. The pest by scale insects (commonly known as "blue lice") occurred during the incubation period, with 1% Omethoate and 25% phoxim EC 1000 times liquid spray once a week. Temporary solution should be a permanent cure, pots and pans to dilute dense, appropriate, high and low placement, increase ventilation, ventilation, reduce disease is appropriate.
