Fertilize and water. Fertilization should abide by the principle of frequent application of thin fertilizer, depending on the variety of orchids, the weather, the temperature and the growth of the plant. In general, spring orchid and cymbidium apply nitrogen and potash fertilizer in summer, Jianlan needs phosphorus and potash fertilizer, while cold orchid can not apply any fertilizer. In addition, do not apply fertilizer to weak plants on cloudy days or when the temperature is too high. Although orchids are fleshy roots, but in the summer with strong light and high temperature, the demand for water is relatively increased, and sufficient moisture must be ensured. In addition to normal watering, foliar spray is carried out around noon to increase air humidity.
