Management and protection of hanging orchids

Cymbidium is a perennial evergreen perennial herbaceous flower with various forms, strong shade tolerance and easy management. It is often used to hang potted plants for indoor decoration or garden setting. The following points should be mastered in its management:

First, temperature control. Cymbidium prefers warm and humid climate and is not cold-resistant. It grows fastest at 20 ℃ and 24 ℃, stops growing at more than 30 ℃, and the leaves are easy to turn yellow and dry. Therefore, summer heat prevention and cooling should be paid attention to ventilation, and cultivation should be carried out in the greenhouse in winter. The overwintering temperature should be 10 ℃, not lower than 5 ℃.

Second, light adjustment. Outdoor cultivation in summer should pay attention to shading, so as not to make the light too strong, otherwise sunburn is very easy to occur. Pay attention to daylighting when overwintering in the shed in winter to prevent the lack of light and the color of the leaves.

Third, the regulation of water and fertilizer. Spring and autumn growth season, watering should be adequate, basin soil should always keep moist, and often spray branches and leaves with water close to room temperature, to prevent dry tip, but not stagnant water. Apply rarefied liquid fertilizer once a month in the peak growing season, water less in winter and stop topdressing.

Fourth, trim and change the basin. As the plant grows, the old leaves at the base should be cut frequently in order to maintain a good plant shape. In addition, the orchid has strong sprouting power, fast growth, easy to grow all over the basin, and the basin should be changed every two years.

Fifth, pest control. The dense plant clusters of Cymbidium are poorly ventilated and vulnerable to scale insects, so prevention should be given priority to. If scale insects occur, 50% marathon emulsion 1000Mel 1500 times can be sprayed once every 7 days, and 2 Mel can be sprayed for 3 times.
