There are four ways to raise a gentleman's orchid

Gentleman orchids like temperature, light, and can not bear the cold. If you want to raise a good gentleman orchid in winter, the key needs to strengthen the management of the following aspects.

Tube soil fertilizer: gentleman orchid likes loose and fertile neutral or weak acid humus soil, should apply less nitrogen fertilizer, more phosphate fertilizer, potash fertilizer. Eggshell powder and retting fish water is a good phosphate fertilizer, bran ash and soot are easily available potash. Fertilization must be appropriate, do not apply thick fertilizer and unfermented raw fertilizer, otherwise, it is easy to cause leaf tip scorch or rot. In winter, if the new leaves are spotted and the roots are yellow, it means that there is too much fertilization, while the narrow, thin and light color of the new leaves is a sign of lack of fertilizer.

Watering: the basin soil should not be too dry and too wet. Every time it is watered, it must be watered thoroughly, and some more should be watered after budding. Fermented bean cake water, fresh fish water and horseshoe water can be combined with watering every 20 days or so to combine watering and fertilization. Watering should be controlled when the room temperature is low to prevent the basin soil from getting too wet.

Heat preservation: the suitable temperature of Cymbidium in winter is 15 ℃-20 ℃, preferably not less than 10 ℃. After jumping, the temperature should be kept at about 18 ℃, and the temperature difference between day and night should be about 10 ℃, otherwise the flower arrow will blossom if it does not reach a proper height, and it is easy to form a "sandwiched arrow".

Adjust the light: although the gentleman orchid likes the semi-overcast environment, the longer the sunshine in winter, the better. Under normal circumstances, it should be placed in the sunny part of the room during the day so that it can shine into the sun. Before flowering, it should also be placed under fluorescent lamps for indoor supplementary lighting at night. Because the two rows of leaves of Cymbidium are opposite, if the light is in one position for a long time, it will make the leaves grow unevenly and affect the ornamental effect. To this end, the adjustment of light should pay attention to the direction of the leaves, every 10 days or so to change to the sunny side.
