Potted Magnolia needs strong management in winter to understand how to cultivate edible fungi.

Gentleman orchid likes temperature, light and can not bear cold. In winter, special attention should be paid to the following management.

Fertilizer and water management: less nitrogen fertilizer and more phosphorus and potassium fertilizer should be applied. Eggshell powder and retting fish water are good phosphate fertilizers, while bran ash and soot are easily available potash. Nitrogen, phosphorus and potassium compound fertilizer can also be applied to promote the germination of more new plants and leaves. 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.

The soil should not be too dry or too wet. Every time it is watered, it must be thoroughly watered, and some more should be watered after budding. Fermented bean cake water, fresh fish water or 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 and causing rotten roots to die.

Temperature management: the suitable temperature of Cymbidium in winter is 15 ℃ to 20 ℃, preferably not less than 10 ℃. The temperature after jumping arrow 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 grow to a proper height, and it is easy to form a clip arrow. Therefore, when the outdoor temperature is lower than 10 ℃ at night, it should be moved indoors. When the indoor temperature is lower than 10 ℃, in addition to covering the surface of the basin soil with a layer of charcoal powder with a thickness of 1 cm, it should also be placed in an indoor sunny warm place. When the indoor temperature is very low, you can cover the flowerpot with a thin film to heat up, but the temperature in the cover should not exceed 25 ℃. If it exceeds, it should be ventilated and cooled down.

Adjust the light: after the orchid enters the room, the light is limited and needs to be adjusted by manually moving the flowerpot. Usually, 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.
