How should orchids be cared for on rooftops, balconies, and windowsills?

Care methods for orchids on rooftops, balconies, and windowsills ① Set up a shade net. In areas where winters are relatively warm, summers are not extremely hot, and there are no typhoons or prolonged rains, set up a shade net.

② Cover the top. At 20 cm below the shade net, cover the top with plastic film or transparent plastic panels to block the washing impact of heavy rain and prolonged rain.

③ Simple warm shed. On the basis of the above measures, add a removable surrounding wall made of plastic film or transparent plastic panels plus shade net around the sides. It can block direct and slanting intense sunlight, avoid the direct and slanting impact of heavy rain, and also block strong winds, exhaust gas, and dust; in areas where winter is not very cold, it can also briefly withstand a low temperature of -2.

④ Greenhouse. A relatively good facility built with aluminum alloy, steel, or wood combined with glass or transparent plastic panels.
