For the planting of Cymbidium, we should pay attention to the following points:

Cymbidium has high requirements for water quality, likes slightly acidic water, and is sensitive to calcium and magnesium ions in water. Rain Water watering is the most ideal. Higher air humidity is needed during the growing period. For example, the humidity is too low, the plant growth is poor, the root growth is slow and small, the leaf becomes thick and narrow, and the leaf color is yellow. Generally speaking, Cymbidium is afraid of dry but not wet.

Light is an important factor affecting the growth and flowering of Cymbidium. Cymbidium belongs to the light-loving class in Orchidaceae. Sufficient light is beneficial to leaf production, flowering stem and flowering. Too much shade, leaves slender and thin, can not be upright, false bulbs become smaller, easy to get sick, affecting flowering. Shading 50% to 60% in midsummer, and more sunshine in autumn, which is conducive to flower bud formation and differentiation. Rainy and snowy days in winter, such as the increase of auxiliary light, is very beneficial to flowering.

Cymbidium likes warm winters and cool summers. The suitable temperature for growth is 10-25 ℃. The night temperature is about 10 ℃. The leaves are green, the flower buds grow and develop normally, the flower stems elongate normally and blossom from February to March. If the temperature is lower than 5 ℃, the leaf is yellow, the flower bud does not grow, the florescence is postponed to April to May, and the flower stem does not elongate, which affects the flowering quality. If the temperature is about 15 ℃, the flower bud will suddenly elongate and blossom from January to February, and the flower stem is soft and can not stand upright. For example, the night temperature is as high as 20 ℃, the leaves grow luxuriantly, affect the flowering, and the buds will wither and yellow. In short, the bud formation, stem extraction and flowering of the orchid all require a large temperature difference between day and night.
