Growth habit of cypripedium grandiflorum

Orchids generally grow on the mountainside valley walls in deep mountains and valleys, in hillsides or crevices with good water permeability and water retention performance, beside sparse mountain grass and under the shade of secondary miscellaneous forests. Or there is shade, short sunshine time or only scattered light. Where the air humidity is high and the air can circulate, it is sometimes born on the cliff next to the mountain stream. Orchids should be planted in a well-ventilated environment. Sex likes cool, avoid direct sunlight, like wet, avoid dry, the most suitable growth in 15℃ to 30℃. Poor growth above 35℃. The severe cold below 5℃ will affect its growth. At this time, orchids are often dormant. If the temperature is too high and the sun is exposed, the leaves will burn or scorch in a day or two. If the temperature is too low and it is not transferred to the house in time, frostbite will occur. Orchids are fleshy roots and are suitable for growing on sandy loam rich in humus. Drainage performance must be good, choose humus soil or mountain soil with more humus. Slightly acidic loose soil or iron-bearing soil, the suitable pH value is 5.5-6.5.
