How to provide shade and rain protection when growing in the open field?

In the South, in areas basically free of frost and with little continuous drizzle, you can grow and acclimate in open-field raised bedswild-collected orchids (Cymbidium)seedlings. When planting the seedlings, arch frames for shade and rain protection should be set up. From midsummer to mid-autumn, because the sun is scorching, a 60% shade net should be used for shading; the rest of the time they can be left under full sun. If there is continuous drizzle, plastic film should be added at any time to keep off the rain. Normally, water, fertilize and spray pesticides as needed. During the frost period, protect against frost. With such extensive management, similar to wild conditions, the survival rate can be as high as over 95%, the sprouting rate is always over 2/3, the growth is vigorous,pests and diseasesare also few.
