1. Light: the large flower of Whelan needs a long time of light. But direct sunlight in summer can cause sunburn, so it needs proper shade. In winter, we should put it in the sun for a long time.
2. Soil: the requirement of Hybrid Cymbidium for soil is not high. It is better to have a fertile and loose acid soil with good drainage. If it is prepared artificially, it is better to choose fern root, bryophyte and so on as the growth medium.
3. Watering: Hybrid Cymbidium has good drought resistance. Its pseudobulb can store water. If the pseudobulb is shriveled and shrunk, it means lack of water. In addition to watering in summer, we also need to spray water on the leaf surface, which can effectively cool down and improve the humidity. And the florescence needs to reduce the amount of water, avoid the flower to fall ill, grow brown spots.
4. Fertilization: Cymbidium requires a lot of fertilizer. In addition to little or no fertilization in seedling stage, thin fertilizer and water can be applied every 10 days in growth stage. Generally, fertilizer should be applied once a week in spring and summer, 2-3 times a month in autumn and stopped in winter. Fertilizer selection nitrogen phosphorus potassium equal compound fertilizer, autumn can apply more potassium fertilizer.
In the propagation of Cymbidium hybridum, the ramet method is often used. It is suitable to divide plants in spring. Take them out of the pot and divide them. Keep more than 3 pseudobulbs for each plant. Cut them and dry them before planting. Generally, it can be divided once every three years, and it is suitable to prevent and cure in warm and humid environment, with new buds, and then carry out normal maintenance.
1. Diseases: the main diseases are leaf blight, anthrax and leaf spot, which can be controlled by carbendazim solution.
2. Insect pest: common insect pests include aphids, spiders and scale insects, etc., which can be sprayed with Omethoate diluent.
